This model is closely based on a watch introduced by MWC in 2005, which was the first to use tritium gas tubes. The self-luminous GTLS tubes make the watch extremely easy to read at night, with consistently bright illumination from dusk until dawn. Each hour and minute hand, as well as the hour markers, contain a brightly glowing vial of tritium gas. Although the vials contain radioactive gas, the total amount is less than the personal limit of 25 millicuries, in accordance with U.S. Nuclear Regulatory Commission regulations 10 CFR 30.15.\u003c\/p\u003e\n\u003ch3\u003eSuperior Night Readability\u003c\/h3\u003e\n\u003cp\u003eMilitary watches of this type are the easiest in the world to read in low light or total darkness due to the self-activated light source, which is up to 100 times brighter than traditional luminous paint. The light-emitting tubes require no battery power or charging and need no maintenance, with a life expectancy of at least 10 years after which they can start to decline.\u003c\/p\u003e\n\u003ch3\u003eRediscovery and Remake\u003c\/h3\u003e\n\u003cp\u003eAlthough this watch range was discontinued by MWC 20 years ago, an interesting turn of events occurred when an MWC distributor in Australia discovered 500 brand-new quartz versions of this range in their storeroom. These watches, made between 1999 and 2001, were part of a procurement contract. When the distributor's son conducted a detailed stock check, these watches came to light. We were offered the opportunity to buy them back, and their popularity prompted us to remake the watches in the same design with significant upgrades.\u003c\/p\u003e\n\u003ch3\u003eUpgrades and Improvements\u003c\/h3\u003e\n\u003cp\u003eAdvances in watch manufacturing over the past 20 years allowed us to enhance the overall specifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Automatic 24 Jewel NH35A with 42 hour power reserve, which can also be hand-wound and has hacking for synchronization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Upgraded from hardened mineral glass to sapphire, which is highly scratch and shatter-resistant.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel:\u003c\/strong\u003e Upgraded to a 120-click bezel versus the earlier 60 or 90-click versions.

Notable models include the Heuer 844-1 (1979) and the Chronosport Sea Quartz 30, worn by Tom Selleck in Magnum PI. Elvia continues to produce watches using this case, and MWC is a factory-authorized distributor for this brand. CWC and other companies also continue to use this case design, which has been in continuous production for over 40 years.\u003c\/p\u003e\n\u003ch3\u003eDimensions and Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCasing:\u003c\/strong\u003e Satin Finish Black PVD Non-Reflective Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e Screw-down Locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 30 ATM \/ 300m \/ 1000ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e NH35A with 24 Jewels and 42 Hour Reserve\u003cmeta charset=\"utf-8\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-end=\"267\" data-start=\"231\"\u003eCase diameter (excluding crown):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e44.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-end=\"316\" data-start=\"280\"\u003eCase diameter (including crown):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e46.0 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-end=\"369\" data-start=\"329\"\u003eCase width (2 o’clock to 8 o’clock):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e42.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-end=\"404\" data-start=\"382\"\u003eLug-to-lug length:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e47.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-end=\"436\" data-start=\"417\"\u003eCase thickness:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e13.1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong data-end=\"470\" data-start=\"449\"\u003eCrystal diameter:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e31 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal Type:\u003c\/strong\u003e Sapphire with non-reflective coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLuminous Material:\u003c\/strong\u003e Swiss GTLS Tritium Gas Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel:\u003c\/strong\u003e 120-click unidirectional with Scratch Resistant Ceramic Insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 89.5g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e Black 20mm Nylon Webbing Strap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap Bars:\u003c\/strong\u003e Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGuarantee:\u003c\/strong\u003e 24 months\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBenefits of Sapphire Crystal\u003c\/h3\u003e\n\u003cp\u003eSynthetic sapphire is the best material for watch crystals due to its strength and shatter and scratch resistance. These characteristics make it appealing to military and security personnel, police officers, and active outdoor enthusiasts, who account for over 70% of our customers. When clients have accidents resulting in a cracked crystal, over 90% involve watches with mineral glass crystals. Even hardened mineral crystals do not match sapphire's durability under adverse conditions. Sapphire crystals are heat-treated to remove internal stresses, enhancing their strength, and are made into watch crystals with two layers of anti-reflective coating. While more expensive, sapphire crystal is typically fitted to higher-end watches and is now used in the latest iPhone models.\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"MWC - Military Watch Company","offers":[{"title":"Default Title","offer_id":50847315558730,"sku":"DV2001PV\/AU\/SLCB","price":611.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1140\/1866\/products\/DV2001_PV_AU_GTLS_OCT0022b.jpg?v=1666267180","url":"https:\/\/mwcwatch.com\/products\/mwc-automatic-black-pvd-military-divers-watch-tritium-gtls-illumination-and-sapphire-crystal-copy","provider":"MWC - Military Watch Company","version":"1.0","type":"link"}
