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 HAB002J1 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 does the quick-change strap system work?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eA button on the case releases the bracelet or strap without tools or spring bar levers. A replacement presses into place until it locks. Seiko offers reinforced silicone straps in white and black that are compatible with this case, sold separately, so the same watch can run formal on titanium and casual on silicone.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eHow does the dual-time function work?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eThe second time zone is displayed on a 24-hour sub-dial in hours and minutes, so a glance tells you both the time and whether it is day or night in the other zone. The time transfer function swaps the main dial and sub-dial readings, letting you promote your second zone to the main hands on arrival. The main hands can also be adjusted manually to a different zone.\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.

At 100-metre water resistance it is rated for swimming and recreational water activity. It is not a diver's watch and is not rated for scuba diving.
