The watch features a robust stainless steel case and is equipped with a high-performance automatic 21,600 bph 21-jewel self-winding movement. We have made several upgrades to the original design, including a shatter and scratch-resistant sapphire crystal and an increased water resistance rating. The dial and caseback are both unbranded (referred to in the military as sterile), giving the watch a clean, uncluttered appearance.\u003c\/p\u003e\n\u003ch3\u003eHistorical and Technical Background:\u003c\/h3\u003e\n\u003cp\u003eThis watch is based on a 1980 UK MOD specification for automatic diver's watches (DEF STAN 66-4 [Part 1] Issue 3). This specification called for a unidirectional bezel and a boldly marked dial with tritium paint and a mineral glass crystal. Although this watch is made in the spirit of the 1980 watches, it includes improvements such as the sapphire crystal, Non Radio Active Luminova and increased water resistance.\u003c\/p\u003e\n\u003ch3\u003eKey Features and Upgrades:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e High-performance automatic 21,600 bph 21-jewel self-winding movement with a 40-hour reserve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Shatter and scratch-resistant sapphire crystal with anti-reflective coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 300m \/ 1000ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Sterile dial and caseback for a clean appearance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVisibility:\u003c\/strong\u003e Uses Luminova for excellent nighttime visibility\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e 20mm NATO strap, with a variety of color options available for easy customization\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications:\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\u003eCrown:\u003c\/strong\u003e Screwdown locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaseback:\u003c\/strong\u003e Screw caseback\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 89.5g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e 21-jewel 21,600 bph with a 40-hour reserve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e 20mm NATO webbing strap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Giftbox included\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 heat treatment to remove 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 very 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":39784372273267,"sku":"SUB\/MILSSAU\/MY","price":381.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1140\/1866\/products\/SUB_MIL_SS_AU-2021_MAY0483Bnewdate_c45f4b85-186d-49dd-99ad-be447812baca.jpg?v=1643127663","url":"https:\/\/mwcwatches.com\/ca\/products\/mwc-21-jewel-1980s-pattern-300m-automatic-military-divers-watch-with-sapphire-crystal-and-a-black-and-a-grey-nato-strap","provider":"MWC - Military Watch Company","version":"1.0","type":"link"}
