MIL-W-46374B

Military-pattern field watch built on the MIL-W-46374B layout: matte black dial with 12- and 24-hour Arabic numerals, sword hands, triangular lume plots, and the "H3" tritium designation alongside the radiation trefoil. The case is stainless steel, measuring 32.7 mm excluding the crown, fitted with a domed acrylic crystal and a screw caseback. The movement is the 7-jewel manual-wind caliber stamped "447 ST.CO." — the Durowe 7420/2, the movement specified for US MIL-W-46374B field watches, with metal bushings in place of train jewels and plastic balance cap jewels, as required by the non-maintainable "expendable" brief of the specification. The inner caseback is stamped "Conde Co. Hong Kong", the case supplier used for watches built to that specification. The MIL-W-46374B revision, published in 1975, is the one that introduced the "H3" marking and the radiation symbol on the dial to declare the tritium luminous material. Important for bidders: the dial carries no maker's signature, and the outside of the caseback carries no military specification, contract number, part number or NSN. This lot is therefore offered as a period military-pattern field watch with specification-type movement and case, and not as an issued military watch attributable to Hamilton, Benrus or any other contractor.

The watch was checked by a watchmaker in September 2026. It winds, runs and sets correctly. The dial printing is crisp, with a few small scattered specks toward the outer edge. The tritium plots and hands have aged to a warm cream tone, as expected of tritium of this age, and are no longer luminous. The acrylic crystal shows light surface marks from use. The brushed steel case is clean, with defined edges and no dents. The leather strap is in fresh condition. Watch only. No box or papers. Shipped fully insured, tracked, and signature-required worldwide.
