Strap for Elegant Collection Automatic 37 Stainless Steel / Grey / Strap

The Longines Elegant L4.810.4.72.2 features a lug width of 19mm. This specific measurement, taken between the attachment pins, is a rare dimension in contemporary watchmaking production and defines this classic dress watch model. To verify compatibility with an aftermarket strap, you must measure precisely between the lugs: even a single millimetre difference would result in improper strap seating.

For the Longines Elegant L4.810.4.72.2, we primarily recommend alligator in dark colourways—black or cognac—for its formal elegance and regular scale texture, which contrasts beautifully against the stainless steel case. Vegetable-tanned calf leather offers an excellent alternative for those who appreciate the natural patina development. Vulcanised rubber maintains formal dignity whilst allowing summer use in humid conditions.

Changing the strap on the L4.810.4.72.2 is accomplished using spring bar removal tools. Position the watch on a soft surface, use a thin spring bar tool to press from the opposite case side, carefully extracting the pin that secures the old strap. Your new 19mm lug width strap simply seats by inserting the spring bar into the lugs, ensuring perfect alignment. Casati Milano offers professional strap change service if preferred.

Absolutely. The L4.810.4.72.2 accepts any artisanal strap with a 19mm lug width. Online you will find selections of ready-to-ship straps in noble materials—alligator, calf, shell cordovan, vulcanised rubber. Compatibility is guaranteed by the 19mm lug width specification, whilst customisation options (length, finishing, monogramming) allow you to tailor the strap to your wrist proportions.

Leather strap longevity on the L4.810.4.72.2 depends on material and usage frequency. Alligator and vegetable-tanned shell cordovan typically deliver 3–5 years under daily wear. Chrome-tanned calf requires replacement every 2–3 years. To extend lifespan, avoid prolonged exposure to humidity, perspiration and direct UV. Casati Milano guarantees their straps for 18 months from purchase date.
