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

There is a distinct weightless quality to this piece—a quiet, metallic frost that settles against the wrist like moonlight. The way the light catches the faceted, blush-toned dial feels less like a functional tool and more like an intimate discovery, an artifact from a time when watchmaking was shifting its focus toward sculptural, accessory-driven silhouettes. It feels smooth, balanced, and remarkably intentional, possessing that rare, cold-touch composure of high-grade mid-century steel.

Born in the mid-1980s, the Lassale line represented Seiko’s pursuit of absolute refinement, evolving from its roots in Swiss ultra-thin engineering into a bold exploration of Japanese jewelry design. This specific reference is a child of the bubble-era ambition, where the integration of case and bracelet became a canvas for architectural precision. Powered by a reliable, slim-profile Japan Quartz movement, it remains a testament to an era where horology was indistinguishable from high fashion.
