A weighted rotor inside Calibre 4R36 spins as your wrist moves, winding the mainspring. Wearing it through a normal day keeps it running. If it stops after sitting unworn, wind it by hand — roughly 30 to 40 turns of the crown — and it will start again.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eWhat happens if I do not wear it for a few days?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eIt stops. The power reserve is approximately 41 hours from a full wind, so a watch taken off on Friday evening will typically have stopped by Sunday. Wind it by hand, reset the time, day and date, and carry on. This is normal for every mechanical watch and does not harm it.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eWhat is the stop second hand function for?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003ePulling the crown out to the time-setting position halts the seconds hand. That lets you line the watch up to the second against a reference before pushing the crown back in, instead of getting the minutes right and the seconds approximately right.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eWhat is the rotating bezel for?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eMeasuring elapsed time. Turn the bezel until its zero marker lines up with the minute hand, and from then on the minute hand reads how long has passed directly off the bezel scale. It turns in one direction only, which is a safety feature: if it gets knocked, it can only ever make the elapsed time read longer than it really is, never shorter.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eIs this a diver's watch?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eNo, and the distinction matters. The case shape and rotating bezel come from Seiko's sports watch heritage, but this model is rated to 100 metres and is not certified as a diver's watch. It is fine for swimming, snorkelling and recreational water activity. For scuba diving you need a watch specified and marked as a diver's watch — the Prospex line is where those sit.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eHow does 42.5mm wear?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eMore comfortably than the number suggests, in footprint at least. The lug-to-lug measurement is 46.0mm, which is genuinely short for a 42.5mm case, so it sits within the wrist rather than hanging over the edges. What you will notice is the weight and height — 169 grams and 14.2mm thick make this a substantial watch. Try it on at any City Chain outlet if you are between sizes.\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 it?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eYes. At 100-metre water resistance it handles swimming and recreational water activity. Never operate the crown while the watch is wet, and make sure the crown is fully pushed in before it goes near water.

Avoid adjusting the date between roughly 9pm and 3am, when the movement's calendar mechanism is engaged and changing it can cause damage.

Links can be added or removed to size it, and the one-push three-fold clasp has a double-lock — a secondary catch that holds the clasp shut if the main one is knocked open.
