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 first sensation is the sharp, geometric cool of the gold-toned links as they find their rhythm against the wrist. The watch wears more like a continuous sculptural cuff than a time-teller, featuring a singular, jutting peak in the case that catches the light in a bold, directional flash. The black dial sits deep within the “Honey Sun” frame, acting as a quiet, shadowy void that anchors the avant-garde lines of the exterior.

Lassale was Seiko’s uncompromising answer to the luxury ultra-thin movement race of the late 20th century. This 1E20 caliber engine is a byproduct of the Daini factory’s peak miniaturization era, allowing for a profile that remains incredibly slender despite the complex, multi-faceted geometry of the case. Its asymmetric silhouette and the integration of black ceramic-style accents on the bracelet speak to a specific window in the 1980s where horology leaned heavily into postmodernism and structural abstraction.
