Why Japanese Pigskin Belongs on Vintage Watches
Why Japanese Pigskin Belongs on Vintage Watches
Japanese pigskin is a natural match for vintage watches. Its distinctive grain and supple hand make it an ideal strap choice, particularly for tool watches and straightforward military three-handers. Our Japanese pigskin is sourced from Ribicoco, a Tokyo-based leather maker focused on sustainable, upcycled leather.
The Grain That Gets Vintage Right
Japanese pigskin is known for its distinctive grain: a field of tiny triangular pores that give the surface a subtly pebbled, organic look. This inherent texture keeps the strap from appearing too “new” or overly shiny next to an aged case.
Unlike some calfskins that start off very smooth and need time to break in, pigskin already carries a quiet, rustic grain that complements patinated dials and worn bezels without competing with them.
Pigskin is usually on the thinner side compared to calfskin or sheepskin, typically around 0.7–0.9 mm. For our KURO straps, we’ve added a supporting layer to bring the overall thickness back to about 2.2–2.5 mm, so it sits and feels in line with the rest of the collection.
The surface of the Japanese pigskin is finished with a light wax treatment, adding an understated, subtle sheen that enhances the leather’s depth without pushing it into high-gloss territory.

Stitchless vs. stitched: two vintage-friendly approaches
Our Japanese pigskin straps is offered in two styles: each suiting different vintage aesthetics.
Stitchless look: understated and integrated
A stitchless construction removes all visual noise and lets the leather’s natural texture speaks for itself. On a vintage tool watch, think a 1960s faded dive watch, this minimalism keeps attention on the dial and case while the strap provides as an understated, integrated support.
Benefits for vintage pairings:
- Cleaner lines that compliments mid-century minimalism
- No contrasting thread to fight with aged lume or faded printing.
- Softer visual weight on smaller, thinner vintage cases.
Light brown / cream stitching: mirroring patina
When you do want stitching, we opted for light brown or cream thread on pigskin which works especially effective with vintage watches with patinated features/ lumes. The warm thread color echoes:
- Creamy, aged lume on hands and markers.
- Faded numerals and chapter rings.
The warmer thread creates a “worn-in from the factory” feel that suits everything from 1950s dress watches to 1970s divers. We also removed the usual edge crease to gives pigskin straps a softer, more relaxed profile. Instead of a crisp, formal edge that can look too sharp next to a rounded, worn case.
This less structured look prevents the strap from appearing too “new” beside a watch that’s clearly been lived with for decades.
