3.3 Recycled,recovered,orenvironmentallypreferablematerials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs.

3.4 Design. There shall be a stem set movement driving concentrically mounted hour, minute, and second hands around a 12 hour dial. The dial background shall be black; the numbers and graduations shall be white. Arabic numerals 1 through 12 shall be adjacent to and inside the hour marks and arranged in a clockwise direction. Concentric with and adjacent to the numerals 1 through 12, in a smaller font, shall be the Arabic numerals 13 through 24. The 13 shall be adjacent to the 1 o’clock; the 14 shall be adjacent to the 2 o’clock; and continuing until the 24 is adjacent to the 12 o’clock. Manufacturer symbols or identification shall not appear on the dial.

3.4.1. Designapproval. At the time of qualification testing, movement and case design shall be reviewed by and subject to the approval of the government. Manufacturer drawings, specifications, sample movements, sample cases, and supporting data, as applicable, shall be submitted for government approval in accordance with 4.6.5.1.

3.4.2 Movement.

3.4.2.1 Class4(mechanical).

3.4.2.1.1 Mechanicalpower. The movement shall be powered by a stem wound and stem set mainspring. When fully wound, the mainspring shall drive the complete movement a minimum of

36 hours without rewinding.

3.4.2.1.2 Jewelbearings,typesIIandIII. The movement shall have 15 or more functional jewel bearings located at bearing points most essential to reduce friction and wear of the train and escapement parts.

3.4.2.2 Classes1,2and3(electrical). Classes 1, 2 and 3 watches shall be powered by a self- contained electrical power cell. For type I classes 2 and 3, types II and III classes 1, 2 and 3 watches, the power cell shall be commercially available from a minimum of two manufacturers and shall contain orientation marks which identify the positive (+) side. Internal contacts for the power cell shall be made of, or plated with, material that shall not corrode. The electrically powered watch shall operate a minimum of 2 1/2 years without the necessity to change the battery.

MIL-PRF-46374G

3.4.3 Handadjustment.

3.4.3.1 Handsetting. The minute hand shall not rotate (jump) at its tip, more than one tip width when the crown is moved from the setting position to the “winding” position after setting the hands.

3.4.3.2 Secondhandstopmechanism. Pulling the stem, by means of the crown, to the setting position shall result in stopping the movement. Rotation of the stem, by turning the crown, shall permit the minute and hour hands to be advanced without any movement of the second hand. Depressing the stem, by pushing the crown, shall result in complete operation of the movement and hands. When the stem is pushed in, the watch shall start immediately.

3.4.4 Elapsedtimering,typeIII. There shall be an elapsed time ring concentric with the axis of the watch. The elapsed time ring shall be designed to assure that the outer edge (shoulder) of the crystal is recessed within the elapsed time ring. The background of the elapsed time ring shall be the same shade of black as the background of the dial. The numbers and graduations shall be the same shade of white as that on the dial. Around the ring there shall be 12 hour marks equally spaced around the dial. Except for the number 12, all the marks shall be numerals starting with 1 and progressing clockwise to 11. The number 12 shall be replaced by a luminous mark. Between the 12 o’clock and 1 o’clock, 1 o’clock and 2 o’clock, 2 o’clock and 3 o’clock, and the 3 o’clock and 4 o’clock marks, there shall be four equally spaced minute marks. The periphery of the elapsed time ring shall be made rough by checkering, knurling, serrating or any method that shall facilitate the turning of the ring. The elapsed time ring shall move only when a torque of 180 ± 40 mNm (26 6 inch-ounces) is applied both in the clockwise and counterclockwise directions. The elapsed time ring shall be capable of withstanding, without damage, two forces, each of 44.5 ± 2

N (10 1/2 pounds), applied to the lower side of the elapsed time ring with the 12 o’clock luminous mark at the 3 o’clock position.

3.4.5 Casebars,typesIIandIII. A watch strap shall be attached to the watch case at both ends by means of integral bars or removable spring bars. A static pull of 67 ± 2 N (15 1/2 pounds) on the watch strap from each end of the case shall cause no damage.

3.4.6 Crystalstrength. Crystals, that have been assembled to the case and that have been subjected to the storage environment of table I, shall be visually inspected and tested for strength. When visually inspected, the crystals shall be transparent, uncolored, and free from bubbles, striae, scratches, chips or other imperfections that may interfere with reading the watch. When functionally tested, the crystal shall show no visible damage of cracking or chipping.

3.4.7 Strap. The strap color shall be black.

4.6.1 Crystals. Crystals shall be examined after assembly to the case and after being subjected to the storage environment of table I to determine compliance with 3.4.6.

4.6.1.1 Crystalstrengthtest. The crystals shall be functionally tested as follows: The case assembly, including crystal, shall be placed flat, crystal up, on a rubber sheet 0.5 mm (0.02 inch) thick, placed on a horizontal, rigid nonresilient, metal surface. A solid steel sphere weighing 15.7

1.4 grams (0.55 0.05 ounces) and 1.6 cm (five-eighths of an inch) in diameter shall then be freely dropped so as to fall 30.5 cm (12 inches) before striking the crystal. Any visible damage to the crystal shall be cause for rejection.

4.6.2 Strap. Thestrapshallbeexaminedfor compliancewith3.4.7.

4.6.3 Case.

4.6.3.1 Batteryservicing. The case shall be visually inspected to determine the conformance to

3.4.9.1. A physical test shall be applied where case parts are not capable of being removed to determine conformance to 3.4.9.1. The physical test shall consist of applying a force or prying under normal pressure (equivalent to 40.5 4.5 N (9 1 pounds) direct force) in such a manner that no marking or scarring of the case and case finish shall result.

4.6.3.2 Finishandcolor. The case shall be visually inspected to determine the conformance to

3.4.9.2.

4.6.4 Radiological.

4.6.4.1 Contamination. Completed watches shall be checked for contamination in accordance with 3.6.1. A Metricel GN-6 or equivalent wipe, moistened with deionized or distilled water, shall be used to wipe the watches. All exterior surfaces of the completed watch shall be thoroughly wiped. The wipe shall be placed in the liquid scintillation solution within

1 minute after wiping each watch. The amount of radiological contamination on the wipe shall be determined using a liquid scintillation counting technique. Results indicating removable contamination over the entire watch of more than 100 dpm shall constitute failure of this test.

4.6.4.2 Diffusionandwaterleakage. Completed watches shall be checked for diffusion in accordance with 3.6.3 and water leakage in accordance with 3.5.5. They shall be submerged in a measured volume of distilled or deionized water, equal to approximately 10 times the volume of the watch, for 24 hours at 23 C 1 C (73 F 3 F). Watches shall be removed from the water. This is the test procedure for radiological diffusion, and if the radioactive content of the water exceeds 50 nanocuries per 24 hour period, it shall constitute failure of the test. The watches shall also be examined for water leakage, and if there is water in the crystal bowl at the completion of the test, it shall constitute failure of the water resistance test. Failure of watches in either of these tests shall be cause for refusal by the government to continue acceptance of the

MIL-PRF-46374G

production watches until evidence has been provided by the contractor that corrective action has been taken to eliminate the deficiencies.

4.6.5 Design. The watch shall be visually examined for conformance to 3.4.

4.6.5.1 Designapproval. Manufacturing data on movement and case design shall be forwarded to the government activity identified in 6.3 (see 3.4.1).

4.6.5.2 Mechanicalpower. Movement identity, design and construction (stem mount and stem set) shall be determined prior to qualification testing for compliance with 3.4.2.1.1. With the watch fully wound, it shall be examined for continuous running, without rewinding, for the minimum time specified in 3.4.2.1.1.

4.6.5.3 Jewelbearings. One percent of the watches under contract, but not less than three watches, shall be examined to ensure the watches contain the appropriate number of jewels placed at the most critical friction points, and are in compliance with 3.4.2.1.2.

4.6.5.4 Electricalpower. Movement identity, design, construction, availability and marking of the power cell shall be determined prior to qualification testing for compliance with 3.4.2.2. The watch shall be tested to ensure that the current drain allows an operating life as specified in

3.4.2.2. The watch shall be measured with a current meter to determine the timekeeping current drain. To allow sufficient latitude in available power, the capacity of the power cell as measured

in milliampere-hours (ma hours) shall be derated by 20 percent to obtain the net power capacity of the power cell. The comparison of power drain from the watch to the power capacity of the derated power cell shall be made to ensure that a minimum life of 30 months can be obtained from the power cell. The internal contacts for the cell shall be inspected for conformance with 3.4.2.2.

4.6.5.5 Handadjustment. A standard type pull gauge with appropriate adapter shall be used to apply the pull specified in 3.4.3. The crown shall not be damaged or separated from the movement when the pull is applied.

4.6.5.5.1 Handsetting. To ensure compliance with the hour and minute “hand” setting of

3.4.3.1, six settings shall be made in 2-hour increments.

4.6.5.5.2 Secondhandstopmechanism. To ensure compliance with the second hand stop mechanism of 3.4.3.2, the second hand setting mechanism shall be activated for at least five different settings, to ensure that a precise stop and start action can be obtained without adverse effect on the hands or movement.

4.6.5.6 Elapsedtimering,typeIII. The elapsed time ring shall be examined for conformance to

3.4.4. The elapsed time ring shall move only when subjected to a torque applied clockwise and counterclockwise of 180 ± 40.0 mNm (26 6 inch-ounces). With the index at the 3 o’clock position of the dial, a force of 44.5 ± 2 N (10 1/2 pounds) shall be applied to the lower side of the elapsed time ring without the ring being damaged or separated from the case.

MIL-PRF-46374G

4.6.5.7 Casebars,typesIIandIII. Type II and III case bars shall be checked for conformance to

3.4.5. With the watch held in a secured position and the strap held in a position that shall not exert pressure on the buckle or the keeper of the strap, a pulling force of 67 ± 2 N (15 1/2 pounds) shall be applied to each case/spring bar via the strap without the case/spring bar permanently bending, loosening or causing damage to the case/spring bar or case assembly.

4.6.5.8 Casemarkings. All numbers and lettering shall be visually inspected for correctness, legibility, and application in accordance with 3.4.8. Inspection for permanent marking shall ensure that acceptable processes have been applied, such as: Casting, molding, steel stamp, acid, etching, or engraving.

4.6.5.9 Vibration. The watch shall be vibrated in accordance with 3.5.1.

4.6.5.10 Shock. In compliance with 3.5.2, while running, the watch shall be dropped from a height of 50 cm (19.7 inches), uncontrolled, onto vinyl tile 3 mm (one-eighth of an inch) thick affixed to concrete block. At the conclusion of this test, the watch shall be running and be subjected to a visual and tactile examination in compliance with 3.4.6 for any crystal damage or loose, missing or damaged parts. After passing this examination, the watch shall be subjected to the test in 4.6.5.11.

4.6.5.11 Storage. In compliance with 3.5.3, the watch shall be subjected to storage temperatures for the times and in the order shown in table I. (Unless otherwise specified, the humidity is the ambient humidity.) Temperature changes in the watch may be gradual to avoid thermal shock.

All watches shall have the battery in the watch. There shall be no evidence of physical defects, damage on the watch, or imperfections of crystal. After passing this test, the watch shall be subjected to and meet the requirements of 3.5.10. NOTE: The mechanical watches shall not be run during storage tests.

4.6.5.12 Waterresistance. The watch shall be examined to determine conformance with 3.5.4. The watch shall be tested by immersing it completely for at least 5 minutes in distilled water containing a wetting agent of approximately 1 percent by weight at room temperature and atmospheric pressure of 1 atmosphere (14.7 pounds per square inch) for 5 minutes. For an additional 5 minutes, the watch shall be immersed under a pressure of 3 atmospheres

(44.1 pounds per square inch). The watch interior shall then be inspected for moisture by placing it on a heating element at 40.6 C 1 C (105 F 2 F) for 5 minutes, then placing several drops of 21 C 1 C (70 F 2 F) water on the center of the crystal. Any visible condensed water (fogging) on the inside of the crystal constitutes failure of this test.

4.6.5.13 Synchronization. The watch shall be examined to determine conformance with 3.5.6. The setting mechanism shall be activated and readings taken when the minute hand is at 12 and the hour hand is at the 3, 6, 9 and 12 hour respectively, to determine compliance with 3.5.6.

4.6.5.14 Magnetism. A magnetic field shall be generated electrically using standard test equipment capable of developing the magnetic intensity (in Gauss) within the limits specified in

3.5.7. With the watch running, it shall be placed into the energized field in the manner specified in

MIL-PRF-46374G

4.6.5.14.1 or 4.6.5.14.2 as applicable, with the stem parallel to the direction of the field. Upon completion and removal from the field, the watch shall be rated by a precision type rate recorder to determine compliance with 3.5.7.

4.6.5.14.2 MagnetismtypesIIandIII. Watches shall be subjected to the field specified in 3.5.7, for 10 minutes.

4.6.5.15 Darkviewing. A dark room shall be used to represent total darkness when conducting the visual examination under the conditions and distance specified in 3.5.8 to determine compliance therewith. Watches shall be in the dark room for at least 8 hours prior to conducting examinations. Individual(s) performing the test shall be acclimated to the dark room for a minimum of 20 minutes prior to conducting the test. There shall be no intervention required, for example, by pushing a button, on the part of the individual in order to read the watch. This test shall be performed no sooner than 60 days after assembly of watches.

4.6.5.16 Isochronism(class4only). This test shall be conducted concurrently with 4.6.5.17 (see 3.5.9).

4.6.5.16.1 TypeI. In the position and at the temperature specified in 3.5.9, the watch shall be fully wound and operated for 4 hours. The watch shall again be fully wound and the rate recorded while fully wound and after 4 hours of operation. The rates shall again be recorded at the 20th and 24th hour. The difference in uniformity of rate between the 4-hour periods shall not exceed 10 seconds.

4.6.5.16.2 TypesIIandIII. This test shall vary from 4.6.5.17 in that the error shall be

determined at 6-hour intervals. The difference of error recorded between each 6-hour period shall not exceed 5 seconds.

4.6.5.17 Accuracy. During the conditioning period, the running watches shall be subjected to the test temperatures of table III for at least 4 hours prior to the test. Daily rates shall be recorded for a period of 3 days in each position and the mean daily rate determined therefrom. The watches shall be rejected if the mean daily rate exceeds the requirements of 3.5.10. The mechanical type watches shall be wound at the beginning of each test and each 24 hours thereafter for the duration of the tests (see 4.6.5.16).
