Seiko describes its approach since then as watchmaking to meet society's evolving needs, following founder Kintaro Hattori's principle of being always one step ahead of the rest. The anniversary collection spans King Seiko, Prospex, Astron, Presage, 5 Sports and Seiko Selection.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eWhy is the dial purple?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eThe anniversary collection is split into three series, each with its own design theme — gold accents for success and prosperity, Seiko Blue, and Edo purple.

The rotating bezel and the SKX case shape both come from Seiko's diving heritage, and the 100-metre rating covers swimming, snorkelling and showering comfortably. But Seiko does not give this reference a diver's designation, so it should not be used for scuba diving. If you want a watch rated for diving, look to the Prospex collection.\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\"\u003eTiming an interval. Line the bezel's zero marker up with the minute hand when you start, and the elapsed minutes can be read straight off the bezel afterwards.

The power reserve is approximately 41 hours from a full wind, so a watch set down on Friday evening will usually have stopped by Sunday. Wind it by hand, reset the time, day and date, and carry on. This is normal for a mechanical watch and does no harm.\u003c\/p\u003e\n      \u003c\/div\u003e\n\n      \u003cdiv class=\"cc-faq-item\"\u003e\n        \u003cp class=\"cc-faq-q\"\u003eCan I swim and shower with it?\u003c\/p\u003e\n        \u003cp class=\"cc-faq-a\"\u003eYes. At 100 metres this handles swimming, snorkelling and showering without concern. Rinse it in fresh water after the sea or a pool, and have the case seals checked at service intervals, since gaskets are what maintain the rating over the years rather than the case itself.\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\"\u003eSubstantially. This is a broad watch at 13.9mm thick and 187 grams on the bracelet, so it has real presence on the wrist. The 46.0mm lug-to-lug is the more useful figure for fit and is shorter than the diameter suggests, which keeps it wearable on medium wrists.
