From a full charge it runs about five months in normal use with no further light exposure, and about 18 months if stored in complete darkness with power saving active. A low battery alert warns you before charge runs short.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eHow is G-STEEL different from a standard G-SHOCK?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eG-STEEL puts a metal bezel over the shock-resistant structure, so the watch reads as metal from the front while the protective architecture stays underneath. The GST-B1000 goes further by pairing that stainless steel bezel with a carbon case and a resin band, which is how it reaches 58 grams and 11.6mm — considerably slimmer and lighter than most metal-faced G-SHOCK models.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eDo I need the app to use it?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eNo. All timekeeping and functions work independently. Pairing with the CASIO WATCHES app over Bluetooth adds automatic time adjustment, easier settings entry, Time \u0026amp; Place and phone finder.

It is not rated for saturation diving or use with helium-based gas mixtures. Make sure the crown is screwed down before entering the water.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eWhat does the screw-lock crown do?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eIt threads down against the case rather than simply pushing in, compressing the crown gasket for a tighter seal. That is what allows the 200-metre rating and prevents the crown being knocked out of position during activity. Unscrew it to set the watch, then screw it back down before any water contact.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eIs 46.9mm too large for my wrist?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eIt is a substantial watch, but two numbers matter more than the diameter here: 11.6mm thick and 58 grams. That combination sits far flatter and lighter on the wrist than the case size suggests, and it clears a shirt cuff more easily than most watches in this category. The band fits wrists from 145mm to 215mm.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eWhat is the difference between the GST-B1000 variants?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eThe GST-B1000-1A is the black dial on a resin band. The GST-B1000-2A pairs the same case with a blue dial finished in vapour deposition, which shifts in tone as light moves across it. The GST-B1000D and GST-B1000BD models run the same module on a metal bracelet rather than resin, which adds weight but changes the register toward formal.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eWhy does the minute hand move in steps?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eThe minute hand advances every 10 seconds rather than sweeping continuously.
