Will it fit? How to measure your wrist

Wrap a strip of paper or a soft tape snugly around your wrist, just below the wrist bone. Mark where it overlaps, then measure that length in centimetres.

If your wrist is the same as or smaller than the Max Wrist size above, it should fit. A watchmaker can usually shorten a vintage bracelet, but extra links are rarely available.

The StoryAbout This Piece

The alternating rhythm of Moonlight silver and Honey gold hearts creates a supple, jewelry-like drape that feels more like a cherished bracelet than a mere instrument of time. When fastened, the polished metal warms quickly against the skin, while the petite, shield-shaped case catches the light with a soft, champagne glow. It is a tactile experience of delicate geometry—small enough to be a quiet companion, yet distinct enough to invite a second glance at the wrist.

Behind the minimalist dial sits the Seiko 1E20 caliber, a pinnacle of 1980s and 90s miniaturization from the legendary Daini factory. During an era where the brand refined the “jewelry watch” category, the 1E20 series allowed for these incredibly slim, sculptural forms without sacrificing the rigorous Japanese quartz precision for which Seiko is known. This specific reference, found here with its original box and documentation, serves as a bridge to an era of design that favored romance and ornamentation in every link.
