WidthLug → buckle · mm
Lug width is the inside gap between your watch’s lugs and must match it. We make any width, for example 19.5. Buckle width is the narrow end, an even number from 10 to 24 mm, never wider than the lug width.
Buckle width cannot be wider than lug width.
LengthLong → short · mm
The long end must be at least as long as the short end.
Thread colorOptional
Keep the thread in the product photos, match it to the leather, choose cream for contrast, or pick another color. Not shown for Stitchless straps.

Curved endOptional
A curved end finishes the strap end in a gentle curve (+$10). It’s a style detail: it isn’t made to match your watch case exactly, so a gap may remain.
PersonalizationOptional
Up to 10 characters, embossed inside the lining. We emboss exactly what you type, so please check spelling and capitals.

PRODUCT DESCRIPTION
This Navy Ostrich leather watch strap is a dark, polished navy, close to ink blue, with lighter blue showing on the raised edges of the scales. Navy stitching blends in along the edges. Pair it with silver, white or light blue dials, and with steel cases.
This is our Slim style, measuring 2.5mm at the lugs and 1.8mm at the tail. It stays flat and close to the wrist, so a slim dress watch or a small chronograph keeps its clean lines.
A rose gold buckle stands out warmly against the navy, while silver ties it to a steel case.
