Lug width and strap fitting for every Rolex model in our index. Tap a watch for the full guide.

Across the 9 Rolex models with standard lugs in our index, lug widths are 19mm (1), 20mm (4), 21mm (4). The most common is 21mm, but don't assume: sizes vary within the brand, so check your exact model below. the Submariner and the Datejust 41 and the Oyster Perpetual 41 and the Explorer 36 and the Explorer 40 use an odd 19mm/21mm lug width (strap options for odd sizes).
