20mm is the most common lug width there is, so it's the one we cut most and the default on every strap. Most dress and everyday watches from 36 to 41mm take it. The 20/16mm taper is the classic dress proportion; 20/18mm is the modern one and suits a slightly larger case.
20/14mm tapers to a 14mm buckle, and every buckle but the Pre-V Stainless, Pre-V Black and Matte Stainless
20/16mm tapers to a 16mm buckle, and every buckle we make
20/18mm tapers to an 18mm buckle, and every buckle we make
20mm straight, 20mm at the buckle, and every buckle we make
Watches with 20mm lugs
Rolex Submariner, Datejust and Explorer, Omega Speedmaster and Seamaster 300, Tudor Black Bay 58, Seiko's Prospex divers, most Hamilton, Longines and Christopher Ward cases, and a long list of microbrands. Yours not there? Measure the gap between the lugs, send us the model, and we'll check it before we cut.
Closer to 19mm or 21mm? Plenty of watches are, and we cut both: 19mm straps and 21mm straps.

Length and leather
At 20mm the registry leans to 20/18mm, with 20/16mm for the smaller and dressier cases. 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.
