{"product_id":"protek-model-3101-titanium-usmc-field-watch","title":"Protek Model 3101 Titanium Field USMC 40mm Watch","description":"\u003cp class=\"product-lead\"\u003eThe Protek Model 3101 is a 40mm titanium field watch built around a USMC-emblem caseback, Swiss Pro-Glo T100 tritium illumination, and a Japanese Miyota Super 2035 quartz movement. It pairs a sapphire crystal with antireflective coating and 100-meter water resistance with a genuine Italian waterproof leather strap in dark brown. The watch ships in one configuration: black dial with dark brown leather strap.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Last in the Field\u003c\/h2\u003e\n\u003cp\u003eThe Protek 3101's case, crown, and caseback are all titanium. Titanium offers a high strength-to-weight ratio, which keeps the total watch weight at 48.4 grams while maintaining a durable enclosure. The crown is fitted with multiple O-rings to support the 100-meter water resistance rating, and the screw-in caseback carries an embossed USMC emblem, machined into the titanium rather than applied as a decal.\u003c\/p\u003e\n\n\u003ch2\u003eTritium Illumination Without Charging\u003c\/h2\u003e\n\u003cp\u003eThe Pro-Glo T100 system uses Swiss-made tritium tubes (the largest available for this series) to produce continuous illumination for up to 25 years without exposure to an external light source. Unlike photoluminescent lume that must be charged by light before it glows, the tritium system is self-powered. Protek states it glows 100 times brighter than conventional photoluminescent alternatives, making the dial readable in low-light conditions without any preparation.\u003c\/p\u003e\n\n\u003ch2\u003eReliable Movement, Readable Crystal\u003c\/h2\u003e\n\u003cp\u003eThe Miyota Super 2035 is a Japanese quartz movement with a stated battery life of four years, reducing the frequency of service intervals in the field. The sapphire crystal sits above the dial with an antireflective coating on the inner surface, cutting glare that would otherwise obscure the dial in bright outdoor conditions. Case thickness is 11mm and lug width is 20mm, fitting a wide range of aftermarket straps if the included leather strap is ever swapped out.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTitanium construction:\u003c\/strong\u003e 40mm case, crown, and screw-in caseback, all titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUSMC emblem caseback:\u003c\/strong\u003e embossed signature emblem machined into the screw-in titanium caseback\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwiss Pro-Glo T100 tritium:\u003c\/strong\u003e self-powered illumination rated for 25 years of continuous glow, 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 movement:\u003c\/strong\u003e Japanese quartz, 3-hand, 4-year battery life\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItalian leather strap:\u003c\/strong\u003e genuine waterproof leather in dark brown with titanium signature buckle\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 diameter\u003c\/td\u003e\n      \u003ctd\u003e40mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCase material\u003c\/td\u003e\n      \u003ctd\u003eTitanium\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\u003eLug width\u003c\/td\u003e\n      \u003ctd\u003e20mm\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\u003eCrystal\u003c\/td\u003e\n      \u003ctd\u003eSapphire with antireflective coating\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMovement\u003c\/td\u003e\n      \u003ctd\u003eJapanese Miyota Super 2035 quartz, 3-hand\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBattery life\u003c\/td\u003e\n      \u003ctd\u003e4 years\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\u003eIllumination\u003c\/td\u003e\n      \u003ctd\u003eSwiss Pro-Glo T100 tritium, 25-year continuous glow\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eStrap\u003c\/td\u003e\n      \u003ctd\u003eGenuine Italian waterproof leather, dark brown\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\u003eCaseback\u003c\/td\u003e\n      \u003ctd\u003eTitanium screw-in with embossed USMC emblem\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDial color\u003c\/td\u003e\n      \u003ctd\u003eBlack\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003ePTK 3101\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 3101 suits buyers who want a field-capable titanium watch with a USMC connection, whether active duty, veterans, or collectors who value the emblem detail. The tritium illumination makes it a practical choice for anyone who needs reliable low-light readability without charging the dial beforehand. The 40mm case and 20mm lug width fit a broad range of wrist sizes.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThe Protek 3101 is not a dive watch and is not rated or designed for diving use despite its 100-meter water resistance. It is available in one configuration only (black dial with dark brown leather strap) and does not include additional strap options or a metal bracelet. The Protek 3101 includes no GPS, compass, or altimeter.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes the tritium illumination require charging before use in the dark?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The Protek 3101 uses a Swiss Pro-Glo T100 tritium system, which is self-powered and glows continuously for up to 25 years without exposure to any external light source. Unlike photoluminescent lume, the tritium tubes in this watch do not need to be charged by sunlight or artificial light before they produce a visible glow.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat movement does the Protek 3101 use, and how long does the battery last?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Protek 3101 runs a Japanese Miyota Super 2035 quartz movement with a 3-hand display. Protek states a battery life of four years for this movement, which reduces how often the watch needs to be serviced or have its battery replaced during extended use.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow water resistant is the Protek 3101, and is it suitable for swimming?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Protek 3101 is rated water resistant to 100 meters, with a titanium crown fitted with multiple O-rings to support that rating. The watch is not described as a dive watch and carries no dive rating; buyers intending scuba or pressurized water use should confirm suitability before purchasing.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat strap does the Protek 3101 come with, and can it be swapped?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Protek 3101 ships with a genuine Italian waterproof leather strap in dark brown, secured by a titanium signature buckle. The lug width is 20mm, which is a standard size that accommodates a wide range of aftermarket straps if the buyer prefers a different material or color.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eCan this watch ship to any US state?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Protek Model 3101 is a watch, not body armor, and is not subject to the New York or Connecticut body armor shipping restrictions. However, tritium-illuminated watches are subject to US Nuclear Regulatory Commission regulations governing tritium devices. Buyers should confirm import or export compliance with applicable regulations before ordering for international destinations.\u003c\/p\u003e","brand":"Protek Watches","offers":[{"title":"Default Title","offer_id":67301470503283,"sku":"TGD-PTK 3101","price":569.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1926\/7025\/files\/ptk-3101_l.jpg?v=1793763343","url":"https:\/\/bulletproofzone.com\/products\/protek-model-3101-titanium-usmc-field-watch","provider":"Bulletproof Zone","version":"1.0","type":"link"}
