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 watch rests on the arm with a surprising sharpness of character, its multi-faceted bezel catching the light like a cut diamond. There is a palpable tension between the cold, brushed surfaces of the Frost-silver steel and the thin, glowing border of Honey-gold that outlines the octagonal frame. When the pebbled chestnut leather meets the skin, the watch transforms from a structural object into a warm, organic extension of the wearer, feeling remarkably slim and intentional.
This 8420-series represents the pinnacle of Seiko’s luxury Credor sub-brand during the early 1980s. Emerging from the elite workshops in Japan, it features a 14K gold bezel—a material choice that signifies the model’s high-end positioning. The dial is a masterclass in subtlety, featuring a fine linen-textured surface and a railway track minute circle that keeps the gaze centered. This caliber was engineered for the era’s obsession with ultra-thin profiles, proving that a dress watch can be both mechanically precise and physically unobtrusive.
