The watch features a robust stainless steel case and is equipped with a high-performance automatic 24-jewel self-winding movement. Several upgrades have been made to the original design, including a shatter and scratch-resistant sapphire crystal and an increased water resistance rating. The dial is unbranded (referred to in the military as sterile), giving the watch a very clean and uncluttered appearance.\u003c\/p\u003e\n\u003ch3\u003eHistorical and Technical Background:\u003c\/h3\u003e\n\u003cp\u003eThis model takes inspiration from the 1980 UK Ministry of Defence specification for automatic diver’s watches (DEF STAN 66-4 [Part 1] Issue 3). It retains hallmark features such as the unidirectional bezel and clearly legible dial, originally marked with tritium.\u003c\/p\u003e\n\u003cp\u003eIn this modern version, we’ve swapped the now-obsolete tritium for non-radioactive Luminova and replaced the original mineral glass crystal with ultra-durable sapphire. The final two images show a scan of the original MOD spec file.\u003c\/p\u003e\n\u003ch3\u003eDimensions and Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 300m \/ 1000ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e 24 Jewel NH35A with a 41-hour reserve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e Screwdown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaseback:\u003c\/strong\u003e Screw caseback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel:\u003c\/strong\u003e Scratch-resistant ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Sapphire with anti-reflective coating*\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eWidth: 45mm including the crown, 40mm excluding the crown\u003c\/li\u003e\n\u003cli\u003eThickness: 15mm\u003c\/li\u003e\n\u003cli\u003eCrystal Diameter: 31mm\u003c\/li\u003e\n\u003cli\u003eLug to Lug: 49mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 170g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e Stainless steel bracelet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 24 months\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBenefits of Sapphire Crystal\u003c\/h3\u003e\n\u003cp\u003eMany customers ask about the benefits of sapphire crystal over standard mineral crystal. Synthetic sapphire is extremely strong, shatter-resistant, and scratch-resistant, making it ideal for military and security personnel, police officers, and active outdoor enthusiasts. These groups account for over 70% of our customer base.\u003c\/p\u003e\n\u003cp\u003eOur observations show that over 90% of incidents involving cracked watch crystals occur with mineral glass. Even hardened mineral crystals do not match the durability of sapphire. Sapphire crystals are strengthened through a heat treatment process that removes internal stresses and are then coated with two layers of anti-reflective coating. While sapphire crystals are more expensive, they offer superior longevity, resilience, and performance, justifying their use in higher-end watches.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003eThese models represent excellent value and are competitively priced for such a high-performance automatic watch. This watch combines the historical design and functional integrity of its predecessors with modern upgrades to meet the needs of today's professionals and enthusiasts.\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"MWC - Military Watch Company","offers":[{"title":"Default Title","offer_id":49789587980618,"sku":"SUB\/MIL\/SS\/AUWBL","price":444.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1140\/1866\/files\/SUB_MIL_SS_AUWBL.jpg?v=1737665372","url":"https:\/\/mwcwatches.com\/ca\/products\/mwc-24-jewel-1982-pattern-300m-automatic-military-divers-watch-with-sapphire-crystal-on-a-stainless-steel-bracelet","provider":"MWC - Military Watch Company","version":"1.0","type":"link"}
