{"product_id":"protek-4101sf-aggressor-carbon-dive-watch","title":"Protek Watches Model 4101SF Aggressor Carbon Dive Watch","description":"\u003cp class=\"product-lead\"\u003eThe Protek Watches Model 4101SF Aggressor Carbon is a 45mm carbon composite dive watch built for demanding use, rated water resistant to 300 meters and equipped with a Swiss Pro-Glo T100 tritium illumination system that glows continuously for 25 years without requiring a charge. It pairs a Japanese Miyota 2035 quartz movement with a sapphire crystal and a 60-click unidirectional ratcheting bezel, and ships in a single configuration: black dial with a charcoal rubber strap.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Handle Depth and Darkness\u003c\/h2\u003e\n\u003cp\u003eThe Model 4101SF carries a 300-meter water resistance rating, and Protek states that every watch is tested in both air and water before leaving the factory. The 316L stainless steel screw-in crown with multiple O-rings and the screw-in caseback work together to maintain that seal under pressure, making the watch a practical choice for diving and water-based work rather than a watch that merely tolerates splashes.\u003c\/p\u003e\n\n\u003ch2\u003eTritium Illumination That Needs No Charging\u003c\/h2\u003e\n\u003cp\u003eThe Swiss Pro-Glo T100 tritium system is self-powered, meaning it emits light continuously through a low-level nuclear process rather than storing energy from an external light source. Protek rates the system for 25 years of continuous glow and describes it as 100 times brighter than conventional photoluminescent lume. For a diver or operator working in low-light or no-light conditions, that means reliable dial legibility regardless of whether the watch was recently exposed to sunlight or a flashlight.\u003c\/p\u003e\n\n\u003ch2\u003eReliable Movement, Durable Crystal\u003c\/h2\u003e\n\u003cp\u003eThe Miyota 2035 quartz movement is a Japanese-made three-hand caliber with a rated four-year battery life, chosen for accuracy and low maintenance over mechanical alternatives. Above it sits a sapphire crystal with an antireflective coating, which resists scratching better than mineral glass and reduces glare that would otherwise obscure the dial in bright conditions. The 60-click unidirectional ratcheting bezel locks elapsed-time readings in place and prevents accidental rotation that could cause a diver to underestimate time underwater.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarbon Composite Case:\u003c\/strong\u003e 45mm case diameter with a 60-click unidirectional ratcheting dive timing bezel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e316L Stainless Steel Hardware:\u003c\/strong\u003e Screw-in embossed signature caseback and screw-in crown with multiple O-rings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSapphire Crystal:\u003c\/strong\u003e Antireflective coating for glare-free dial viewing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e300-Meter Water Resistance:\u003c\/strong\u003e Each watch tested in both air and water\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePro-Glo T100 Tritium:\u003c\/strong\u003e Swiss self-powered illumination, continuous 25-year glow, no external charge required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMiyota 2035 Quartz Movement:\u003c\/strong\u003e Japanese three-hand caliber with four-year battery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRubber Strap:\u003c\/strong\u003e Genuine rubber, 22mm lug width, steel 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 Material\u003c\/td\u003e\n      \u003ctd\u003eCarbon Composite\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCase Diameter\u003c\/td\u003e\n      \u003ctd\u003e45mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCaseback\u003c\/td\u003e\n      \u003ctd\u003e316L Stainless Steel, screw-in, embossed signature\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCrown\u003c\/td\u003e\n      \u003ctd\u003e316L Stainless Steel, screw-in, 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\u003eBezel\u003c\/td\u003e\n      \u003ctd\u003e60-click unidirectional ratcheting dive timing bezel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMovement\u003c\/td\u003e\n      \u003ctd\u003eJapanese Miyota 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\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\u003e300 meters (tested in air and water)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eStrap\u003c\/td\u003e\n      \u003ctd\u003eGenuine rubber, charcoal, steel signature buckle\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLug Width\u003c\/td\u003e\n      \u003ctd\u003e22mm (strap: 22mm x 20mm)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight\u003c\/td\u003e\n      \u003ctd\u003e82 grams\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 4101SF\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 Model 4101SF suits divers, water-sport participants, and tactical users who need a legible, low-maintenance watch in dark or wet environments. The tritium illumination and 300-meter water resistance make it well suited to extended underwater use, and the quartz movement keeps timekeeping reliable without winding or regulation.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis watch is not a mechanical or automatic timepiece and does not include a date complication. No ISO 6425 dive watch certification is stated for this model.

Protek states that every watch in this line is tested in both air and water. The screw-in crown with multiple O-rings and the screw-in caseback maintain the seal under pressure, making the watch suitable for recreational and technical diving within that depth rating.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDoes the tritium illumination need to be charged by a light source?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The Pro-Glo T100 tritium system on the Model 4101SF is self-powered through a low-level nuclear process and does not need to be exposed to sunlight or artificial light to glow. Protek rates the system for 25 years of continuous illumination, so the dial remains legible in complete darkness regardless of prior light exposure.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat movement does the Model 4101SF use, and how long does the battery last?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Model 4101SF uses a Japanese Miyota 2035 quartz three-hand movement with a rated four-year battery life. Quartz movements maintain accurate timekeeping without winding or regulation, and the four-year battery interval means infrequent servicing for everyday or field use.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the lug width, and can the strap be replaced?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Model 4101SF has a 22mm lug width. The watch ships with a genuine rubber charcoal strap measuring 22mm at the lug end and 20mm at the buckle end, secured by a steel signature buckle. Any standard 22mm strap is compatible at the lug end; no quick-release mechanism is listed for this model.\u003c\/p\u003e","brand":"Protek Watches","offers":[{"title":"Default Title","offer_id":67301501927795,"sku":"TGD-PTK 4101SF","price":614.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1926\/7025\/files\/ptk-4101sf_l.jpg?v=1793763445","url":"https:\/\/bulletproofzone.com\/products\/protek-4101sf-aggressor-carbon-dive-watch","provider":"Bulletproof Zone","version":"1.0","type":"link"}
