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 was discontinued by MWC over 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 Seiko NH35 with 24 Jewel, 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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTritium Tubes:\u003c\/strong\u003e Improved performance of Swiss Tritium GTLS tubes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHistorical Case Design\u003c\/h3\u003e\n\u003cp\u003eThese watches are based on a case design originally made by the renowned Swiss case-making firm MRP S.A.

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 data-end=\"198\" data-start=\"167\"\u003eDimensions \u0026amp; Specifications\u003c\/h3\u003e\n\u003cp data-end=\"225\" data-start=\"200\"\u003e\u003cstrong data-end=\"223\" data-start=\"200\"\u003eCase \u0026amp; Construction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-end=\"298\" data-start=\"228\"\u003eCase material: Satin finish black non-reflective PVD stainless steel\u003c\/li\u003e\n\u003cli data-end=\"328\" data-start=\"301\"\u003eCrown: Screw-down locking\u003c\/li\u003e\n\u003cli data-end=\"375\" data-start=\"331\"\u003eWater resistance: 30 ATM \/ 300 m \/ 1000 ft\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-end=\"391\" data-start=\"377\"\u003e\u003cstrong data-end=\"389\" data-start=\"377\"\u003eMovement\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-end=\"426\" data-start=\"394\"\u003eMovement: Seiko NH35 automatic\u003c\/li\u003e\n\u003cli data-end=\"441\" data-start=\"429\"\u003eJewels: 24\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-end=\"459\" data-start=\"443\"\u003e\u003cstrong data-end=\"457\" data-start=\"443\"\u003eDimensions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-end=\"504\" data-start=\"462\"\u003eCase diameter (excluding crown): 44.5 mm\u003c\/li\u003e\n\u003cli data-end=\"549\" data-start=\"507\"\u003eCase diameter (including crown): 46.0 mm\u003c\/li\u003e\n\u003cli data-end=\"598\" data-start=\"552\"\u003eCase width (2 o’clock to 8 o’clock): 42.5 mm\u003c\/li\u003e\n\u003cli data-end=\"629\" data-start=\"601\"\u003eLug-to-lug length: 47.5 mm\u003c\/li\u003e\n\u003cli data-end=\"657\" data-start=\"632\"\u003eCase thickness: 13.1 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-end=\"679\" data-start=\"659\"\u003e\u003cstrong data-end=\"677\" data-start=\"659\"\u003eCrystal \u0026amp; Lume\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-end=\"734\" data-start=\"682\"\u003eCrystal type: Sapphire with non-reflective coating\u003c\/li\u003e\n\u003cli data-end=\"762\" data-start=\"737\"\u003eCrystal diameter: 31 mm\u003c\/li\u003e\n\u003cli data-end=\"809\" data-start=\"765\"\u003eLuminous material: Swiss tritium gas tubes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-end=\"831\" data-start=\"811\"\u003e\u003cstrong data-end=\"829\" data-start=\"811\"\u003eStrap \u0026amp; Weight\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli data-end=\"874\" data-start=\"834\"\u003eStrap: Black 20 mm nylon webbing strap\u003c\/li\u003e\n\u003cli data-end=\"902\" data-start=\"877\"\u003eStrap bars: Spring bars\u003c\/li\u003e\n\u003cli data-end=\"921\" data-start=\"905\"\u003eWeight: 89.5 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-end=\"937\" data-start=\"923\"\u003e\u003cstrong data-end=\"935\" data-start=\"923\"\u003eWarranty\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-end=\"962\" data-start=\"938\"\u003e\n\u003cli data-end=\"962\" data-start=\"938\"\u003e\n\u003cp data-end=\"962\" data-start=\"940\"\u003eGuarantee: 24 months\u003c\/p\u003e\n\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":49361844633930,"sku":"DV2001\/PVAU\/SL35","price":620.0,"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:\/\/mwc-usa.com\/products\/mwc-automatic-black-pvd-military-divers-watch-tritium-gtls-illumination-sapphire-crystal-and-24-jewel-nh35-movement","provider":"MWC - Military Watch Company","version":"1.0","type":"link"}
