The rest of the case is titanium with a super-hard coating in its natural silver finish, and the dial is black.

The chronograph now measures up to 24 hours instead of 12. The second time zone is read on a 24-hour sub-dial rather than a 12-hour one, which does away with a separate AM\/PM indicator. And the new movement allowed Seiko to arrange the sub-dials horizontally and slim the case to 12.4mm.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eWhy does a 24-hour chronograph matter?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eBecause most stopwatches stop counting at 12 hours, which means a long-haul flight, an overnight drive or a full working day has to be tracked mentally once the counter wraps around. This one runs a complete 24-hour cycle on a single measurement, in 1\/20-second increments, with split-time capability for intermediate readings.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eWhat does GPS Solar actually do?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eThe watch receives signals from GPS satellites to identify where it is, then adjusts its time and time zone to match — with a high-speed time zone adjustment and automatic daylight saving correction. Manual time adjustment is available if you prefer to set it yourself. All the energy for this comes from light striking the dial.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eDo I ever need to change the battery?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eNo. The HAB003J1 charges from any light source into a rechargeable cell. A full charge runs the watch for approximately six months, and the power save function extends that to around two years when it is left in the dark. Everyday wear keeps it topped up indefinitely.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eHow do I care for the silicone strap?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eRinse it with fresh water after exposure to sweat, salt water or chlorine, and dry it before storing. Silicone attracts dust and lint, so an occasional wipe keeps it looking clean. Keep it away from solvents, and avoid leaving it in direct sunlight for extended periods when not being worn.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eCan I swim with this watch?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eYes. At 100-metre water resistance it is rated for swimming and recreational water activity, and the silicone strap suits water use better than leather or metal. It is not a diver's watch and is not rated for scuba diving. Do not operate the crown or the chronograph pushers while the watch is submerged.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eHow does 43.4mm wear?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eBetter than the number suggests. The case is 12.4mm thick — a full millimetre slimmer than the outgoing Astron chronograph — and the two-piece octagonal bezel is designed to keep the centre of gravity low. Titanium and silicone together make this the lightest configuration in the range.
