The green camo dial and charcoal rubber strap give it a tactical field aesthetic suited to active outdoor and professional use. One configuration is available: carbon composite case with green camo dial and charcoal rubber strap.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Handle Real Depth and Darkness\u003c\/h2\u003e\n\u003cp\u003eThe Aggressor 4105SFC carries a 300-meter water resistance rating, and Protek states that every watch is tested in both air and water before leaving production. The screw-in crown features multiple O-rings, and the caseback is a screw-in 316L stainless steel embossed signature design, both construction details that support the depth rating rather than leaving it to the case alone. For divers and water-sport users, that combination of tested rating and redundant sealing means the spec is not just a number on a box.\u003c\/p\u003e\n\n\u003ch2\u003eTritium Illumination That Requires Nothing From You\u003c\/h2\u003e\n\u003cp\u003eThe Swiss Pro-Glo T100 tritium system is self-powered: it does not need to be charged by sunlight, a flashlight, or any external source. Protek states it glows continuously for 25 years and is 100 times brighter than conventional photoluminescent lume. For low-light field use, night diving, or any situation where charging a watch face is not practical, tritium illumination removes a variable that photoluminescent lume cannot.\u003c\/p\u003e\n\n\u003ch2\u003eSapphire Crystal and a 60-Click Dive Bezel\u003c\/h2\u003e\n\u003cp\u003eThe sapphire crystal carries an antireflective coating for glare-free reading in bright or overhead-light conditions. The unidirectional ratcheting dive timing bezel has 60 clicks, giving precise elapsed-time tracking with no risk of accidentally rotating it forward and reading a shorter elapsed time than actual, a standard safety feature for dive timing. The Miyota 2035 Japanese quartz movement drives a 3-hand display and is rated for a 4-year battery life under normal use.\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 with 60-click unidirectional ratcheting dive timing bezel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePro-Glo T100 Tritium Illumination:\u003c\/strong\u003e Swiss self-powered system, continuous 25-year 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\u003e316L Stainless Steel Hardware:\u003c\/strong\u003e Screw-in embossed caseback and screw-in crown with multiple O-rings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMiyota 2035 Quartz Movement:\u003c\/strong\u003e Japanese 3-hand movement with 4-year battery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGenuine Rubber Strap:\u003c\/strong\u003e 22mm lug width, charcoal color, with 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 Diameter\u003c\/td\u003e\n      \u003ctd\u003e45mm\u003c\/td\u003e\n    \u003c\/tr\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\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\u003eMiyota 2035 Japanese 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\u003e300 meters (tested in air and water)\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\u003eStrap\u003c\/td\u003e\n      \u003ctd\u003eGenuine rubber, charcoal, 22mm x 20mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBuckle\u003c\/td\u003e\n      \u003ctd\u003eSteel signature buckle\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLug Width\u003c\/td\u003e\n      \u003ctd\u003e22mm\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\u003c\/td\u003e\n      \u003ctd\u003eGreen camo\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003ePTK 4105SFC\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 Aggressor 4105SFC suits divers, outdoor professionals, and tactical users who need a watch that functions reliably at depth, reads clearly in low light without any preparation, and holds up to physical use. The 300-meter water resistance rating and self-powered tritium illumination make it a practical choice for anyone who cannot rely on charging a lume dial before a dive or night operation.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThe 45mm carbon composite case and tactical dial are purpose-built for field and water use, not dress or everyday-casual wear. Buyers seeking a slim profile, a metal bracelet, or a mechanical automatic movement will need to look at other models, as this configuration ships only with a rubber strap and quartz movement.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat does 300-meter water resistance mean in practice?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Protek Aggressor 4105SFC is rated to 300 meters water resistance, and Protek states every unit is tested in both air and water. At this rating, the watch is suitable for recreational scuba diving and high-impact water activities. The screw-in crown with multiple O-rings and screw-in caseback support that rating at depth.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eHow does the tritium illumination work, and does it need to be charged?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Aggressor 4105SFC uses the Swiss Pro-Glo T100 tritium system, which is self-powered by tritium gas tubes. It requires no exposure to light to activate and glows continuously for approximately 25 years. Protek states it is 100 times brighter than conventional photoluminescent lume systems, making it readable in complete darkness without any preparation.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat movement does the Aggressor 4105SFC use, and how long does the battery last?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe watch runs on a Miyota 2035 Japanese quartz movement with a 3-hand display. Protek rates the battery life at 4 years under normal use. The Miyota 2035 is a widely used quartz caliber known for reliability and straightforward battery replacement at any watchmaker.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat strap does this watch come with, and can it be swapped?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Aggressor 4105SFC ships with a genuine charcoal rubber strap measuring 22mm at the lug end and 20mm at the buckle end, secured by a steel signature buckle. The 22mm lug width is a standard size, so aftermarket straps with a 22mm lug width are compatible, though only the rubber strap is included.\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 Aggressor 4105SFC is a timepiece, not body armor, and carries no state-level shipping restrictions.
