Shell cordovan is one of the rarest and most desirable leathers in the world. Produced from a layer of material located just over a horse’s hip, the result is a strong yet supple leather that does not crease. After a six-month tanning process, it develops a unique, rugged, rippling patina unlike anything else. Due to its strength, the straps can be made thin — these are just 2mm thick. Combined with color-matched stitching, the result is a robust and elegant strap, tapering down to a refined 16mm at the buckle to ensure comfort during wear on everything from a vintage dress watch to a scratched-up tool watch.
