It is offered in a single configuration: dark blue dial with a genuine Italian leather dark tan strap.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt Around Titanium\u003c\/h2\u003e\n\u003cp\u003eThe Protek Model 3103's case, crown, caseback, and strap buckle are all titanium. The 40mm case carries IP black plating and a fixed bezel, while the screw-in caseback is embossed with the USMC signature emblem. The titanium crown is fitted with multiple O-rings to maintain the watch's 100-meter water resistance rating. Titanium construction keeps the total weight to 48.4 grams, which reduces fatigue during extended wear.\u003c\/p\u003e\n\n\u003ch2\u003eContinuous Low-Light Legibility\u003c\/h2\u003e\n\u003cp\u003eThe Model 3103 uses the Swiss Pro-Glo T100 self-powered tritium illumination system, which glows continuously for 25 years without requiring exposure to an external light source. Protek states this series uses the largest tritium tubes available in the line, and that the system glows 100 times brighter than conventional photoluminescent lume. The sapphire crystal carries an antireflective coating to reduce surface glare during daylight reading.\u003c\/p\u003e\n\n\u003ch2\u003eReliable Quartz Movement\u003c\/h2\u003e\n\u003cp\u003eTimekeeping is handled by the Japanese Miyota Super 2035 quartz three-hand movement, which carries a stated four-year battery life. Quartz movements require no winding or positional accuracy management, making the Model 3103 a low-maintenance choice for buyers who want consistent accuracy without mechanical upkeep.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTitanium case and hardware:\u003c\/strong\u003e 40mm case with IP black plating, fixed bezel, screw-in embossed USMC caseback, and titanium signature buckle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwiss Pro-Glo T100 tritium illumination:\u003c\/strong\u003e self-powered, glows continuously for 25 years, no charging required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSapphire crystal:\u003c\/strong\u003e antireflective coating for glare-free viewing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMiyota Super 2035 quartz movement:\u003c\/strong\u003e Japanese-made, three-hand, four-year battery life\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater resistant to 100 meters:\u003c\/strong\u003e titanium crown with multiple O-rings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGenuine Italian leather strap:\u003c\/strong\u003e waterproof dark tan leather, 20mm lug width\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCase material\u003c\/td\u003e\n      \u003ctd\u003eTitanium with IP black plating\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCase diameter\u003c\/td\u003e\n      \u003ctd\u003e40mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCase thickness\u003c\/td\u003e\n      \u003ctd\u003e11mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBezel\u003c\/td\u003e\n      \u003ctd\u003eFixed\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCaseback\u003c\/td\u003e\n      \u003ctd\u003eTitanium screw-in, embossed USMC emblem\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCrown\u003c\/td\u003e\n      \u003ctd\u003eTitanium with multiple O-rings\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCrystal\u003c\/td\u003e\n      \u003ctd\u003eSapphire with antireflective coating\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDial color\u003c\/td\u003e\n      \u003ctd\u003eDark blue\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMovement\u003c\/td\u003e\n      \u003ctd\u003eJapanese Miyota Super 2035 quartz, three-hand\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBattery life\u003c\/td\u003e\n      \u003ctd\u003e4 years (stated)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eIllumination\u003c\/td\u003e\n      \u003ctd\u003eSwiss Pro-Glo T100 tritium, self-powered, 25-year continuous glow\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWater resistance\u003c\/td\u003e\n      \u003ctd\u003e100 meters\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eStrap material\u003c\/td\u003e\n      \u003ctd\u003eGenuine Italian waterproof leather, dark tan\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLug width\u003c\/td\u003e\n      \u003ctd\u003e20mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBuckle\u003c\/td\u003e\n      \u003ctd\u003eTitanium signature buckle\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003e48.4 grams\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003ePTK 3103\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe Protek Model 3103 suits buyers who want a lightweight titanium field watch with continuous tritium illumination and a USMC-themed caseback: active service members, veterans, and civilians who prioritize low-light legibility and low-maintenance quartz accuracy. The 100-meter water resistance and screw-in caseback make it appropriate for general field and water-adjacent use.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThe Model 3103 is not a dive watch and is not rated for pressurized or deep-water diving. It carries no rotating dive bezel. Buyers seeking a mechanical or automatic movement will need a different model, as this watch uses quartz only. It is available in one dial and strap configuration; buyers wanting alternate colors should look at other models in the 3100 series.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat makes the tritium illumination different from standard lume?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Protek Model 3103 uses the Swiss Pro-Glo T100 tritium system, which is self-powered by radioactive decay and glows continuously for 25 years without needing to be charged by sunlight or artificial light. Protek states the system is 100 times brighter than conventional photoluminescent lume, and this model uses the largest tritium tubes available in the series.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eIs the Protek Model 3103 suitable for swimming or water activities?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Protek Model 3103 is water resistant to 100 meters, supported by a titanium crown with multiple O-rings and a screw-in caseback. This rating is generally considered adequate for swimming and snorkeling. It is not rated for pressurized diving, and BPZ recommends consulting a watchmaker before any high-pressure water exposure.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the battery life and how difficult is it to replace?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Miyota Super 2035 quartz movement in the Protek Model 3103 carries a stated four-year battery life. Battery replacement requires opening the screw-in caseback, which BPZ recommends having done by a qualified watchmaker to preserve the water-resistance seal.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDoes the strap fit standard 20mm watch bands?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The Protek Model 3103 has a 20mm lug width, which is a standard size. The included strap is genuine Italian waterproof leather in dark tan with a titanium signature buckle. Any aftermarket 20mm strap can be fitted, though replacing the strap may affect the water-resistance seal at the case.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eCan this watch be shipped to any US state?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Protek Model 3103 is a watch and is not subject to body armor shipping restrictions. No state-level restrictions are known to apply to this product. Under 18 U.S.C. § 931, the body armor prohibition applies to body armor, not to watches; no equivalent federal restriction applies to this item.\u003c\/p\u003e","brand":"Protek Watches","offers":[{"title":"Default Title","offer_id":67301458772339,"sku":"TGD-PTK 3103","price":569.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1926\/7025\/files\/ptk-3103_l.jpg?v=1793763257","url":"https:\/\/bulletproofzone.com\/products\/protek-model-3103-usmc-titanium-field-watch-dark-blue-dial","provider":"Bulletproof Zone","version":"1.0","type":"link"}
