21mm Leather Watch Bands & Straps

21mm watch straps for Rolex, Omega, Grand Seiko and Longines cases that fall between the common sizes. Tapered to 18 or 16mm.

A width the big makers use and few strap shops cut. Made to order at 21mm in nine leathers and three lengths or a custom one.

21mm Leather Watch Bands & Straps

Every cut tapers

21mm is a width the big Swiss and Japanese makers use and almost no strap shop stocks. A 20mm strap leaves a visible gap at each lug; a 22mm won't fit between them. We make ours to order at 21mm, tapered to 18 or 16mm at the buckle.

Watches with 21mm lugs

The Rolex Datejust 41 and Sea-Dweller, Omega's larger Seamaster and Aqua Terra cases, Grand Seiko's 40mm sport models, several Longines and Jaeger-LeCoultre references and the Orient Bambino. Yours not there? Measure the gap between the lugs, send us the model, and we'll check it before we cut.

Measured 20mm or 22mm after all? See the 20mm straps or the 22mm straps.

Length and leather

At 21mm we recommend 21/18mm across the list, which keeps the buckle in proportion to a 40mm case. Three lengths, Short (105/65mm) to Long (125/85mm), or a custom one, and the sizing guide helps you pick. Every leather we make is cut to any width: shell cordovan, the Classic and Vintage series, lined or unlined.
