Unlike photoluminescent lume - which must be \"charged\" by exposure to light and fades within hours - the Pro-Glo T100 tritium system on this watch glows continuously for 25 years and is 100 times brighter than conventional lume. This makes it ideal for diving, tactical use, or any situation where reliable, always-on illumination is critical.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eIs this watch safe to use for scuba diving?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eYes. The PT4105SFC is water resistant to 300 meters, which far exceeds the depth requirements for recreational and technical scuba diving. It features a screw-in crown with multiple O-rings, a screw-in caseback, and every watch is individually tested in both air and water before shipping to verify its water resistance rating.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the unidirectional bezel do and why does it matter for diving?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eThe 60-click unidirectional ratcheting bezel allows divers to track elapsed time underwater. Because it only rotates counterclockwise, any accidental bump or knock will only make the time reading appear shorter - never longer - which is a critical safety feature. If your elapsed time appears shorter than it actually is, you'll surface sooner, which errs on the side of caution for air supply management.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow long does the battery last and can it be replaced?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eThe Miyota 2035 quartz movement is rated for a 4-year battery life under normal use. When the battery needs replacing, it should be taken to a qualified watchmaker or service center to ensure the water-resistant seals are properly reseated and the watch's water resistance rating is maintained after servicing.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat is the lug width, and what replacement straps are compatible?\u003c\/summary\u003e\n    \u003cp class=\"faq-content\"\u003eThe PT4105SFC has a 22mm lug width, which is a widely available standard size.
