What does “Lugs” mean?

Lugs are the projections at the top and bottom of the case where the bracelet or strap attaches, usually with spring bars. Lug-to-lug length, written L2L, is the distance from the tip of the top lugs to the tip of the bottom lugs, and it has a big effect on how a watch wears: a case can have a modest diameter but long lugs that overhang a small wrist. Lug width, the gap between the lugs, decides which bracelets and straps fit.

Lugs also matter for condition. Sharp, unpolished lugs with crisp edges and original bevels are highly valued, especially on vintage and neo-vintage watches, while heavy polishing rounds them off and lowers value. Dealers look closely at the lugs in photos for signs of polishing, dents and whether the lug holes are drilled through, which is period-correct on some older references. Buyers asking about fit will often request the lug-to-lug measurement in millimetres.

Example: 'Lugs unpolished, sharp bevels, lug-to-lug about 48 mm.'
