A pioneer of quartz since the 1969 Astron, the first quartz wristwatch to be put on sale, the brand then introduced this technology into its everyday watches: the Silver Wave is one example, produced in several cases and dials around calibres such as the 7546 in this piece.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe dial indicates 7546-8380: is that the correct reference?\u003c\/strong\u003e \u003cbr\u003eYes. At Seiko, the code printed at the bottom of the dial is that of the dial itself, not that of the watch. The watch reference is engraved on the caseback, here 7546-8340: the first group designates the calibre, the second the case. A difference between the two codes is normal and is found on most Seiko from this period.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the dial and bracelet original?\u003c\/strong\u003e\u003cbr\u003eYes.

A quartz movement requires neither winding nor daily setting: you simply put it on your wrist. The battery has been replaced, and its next replacement takes only a few minutes at a watchmaker's. As with any vintage watch, water resistance is not guaranteed: it should be removed before showering or swimming.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this piece suitable for a slim or larger wrist?\u003c\/strong\u003e\u003cbr\u003eWith a 36mm diameter, 41mm Lug-to-lug and 10.5mm thickness, it suits wrists from about 15 to 18cm — a guide, never a rule: everyone wears what they like.
