Lug

Lugs are the extensions of the case that hold the ends of the watch strap or bracelet. They seem like a secondary detail, but they define almost everything: how the watch sits on the wrist, how much weight the wearer perceives, whether the case integrates with what follows it or remains an isolated body.

Geometry matters more than you'd think. Straight lugs — those that depart orthogonally from the case — are typical of vintage chronographs from the Fifties and Sixties, the Speedmaster CK2915 and CK2998 above all. Curved lugs, angled downward, reduce protrusion and make larger diameters wear better: when Chopard shortens and lowers them on the Mille Miglia, a 43mm gains discretion on the wrist. The lyre lugs of the classic Speedmaster Professional have a lyre-shaped form recognizable at a glance; the dog-leg lugs of the Fifties Seamaster recall a dog's paw and were revived on the Milano Cortina 2026 model. Triple lugs — three extensions per side instead of two — appear on some contemporary productions like the Roger Dubuis Excalibur.

Articulated lugs, called floating lugs, are a different chapter. De Bethune has used them since 2010 on the DB28 line: made in titanium, they move slightly following the curve of the wrist. It's not aesthetics — it's ergonomics applied to the junction between case and wrist.

At the opposite end are lugless cases, without protruding lugs. The bracelet or watch strap attaches directly beneath the bezel or within the case geometry. The silhouette becomes continuous, the nominal diameter matters less because the actual bearing surface is reduced. It's a solution some use correctly to make a 44mm look compact.

Integrated lugs — machined as one piece with the case — guarantee superior structural rigidity compared to soldered or screwed-on lugs. On the Pequignet Royale I finish them with a brushed upper surface and polished sides: at that point they become a style element too.

The measurement that divides the upper lugs from the lower ones is called lug width. It's the vertical distance of the case, and in certain cases it's more important than the diameter for understanding how a watch really wears. A 38mm with a lug width of 43mm — like certain Villerets — disappears on the wrist. A 40mm with a lug width of 51mm rides the wrist like a diver. I always keep a caliper on the bench: it's the first measurement I take on a watch I don't know.
