The MIL-W-46374B manual winding watch - like the mid-1980s United States military-issue one here - has both 12 and 24 hour markers and its dial has a very Cold War-esque radioactive symbol, indicating the luminous markers (hands and dial, per picture) are radioactive (luminosity is provide by a safe H3 tritium coating).
The “B” version of the 46374 made its U.S. military debut in May 1975, and was produced through April 1983. No fancy buttons or bezels. Just a very simple and reliable watch that does what it is specified to do – tell time on the battlefield.
Since the watch was first worn, it has been an information tool, giving its wearer some piece of intelligence otherwise not known. Perhaps nowhere is that truer or better realized than in the military watch. Almost as long as watches have existed, governments and military's have been buying and issuing timepieces to be used in nearly every military scenario imaginable.
These 46374B USMIL-issued watches have held up quite well, especially for collectors who like to wear their watches. Strictly utilitarian, these watches have served as functional instruments, designed to give their wearers specific and accurate information in environments not often encountered by civilian watches.
This watch comes with two nylon NATO straps, its original nylon ZULU strap, hard plastic travel case, and springbar tool.
USMIL-Issued Mid-1980s Hamilton MIL-W-46374B Mechanical Watch

CASE: Bead-blasted anti-reflective stainless-steel case measures 34mm (35.5mm w/crown) x 40.5mm. Of note, these featured fixed bars - vice removeable springbars - rendering them only suitable for ZULU or NATO straps.

BAND: This 46374B comes with two NATO straps, with stainless steel hardware, both of which compliment the military look of this Hamilton. This watch also includes its original nylon ZULU strap, with PVD hardwere (bare stainless-steel would catch light at night and give away the wearer's position, after all).
