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

The lug width of the Longines Elegant L4.810.4.77.2 is 19 millimetres. This non-standard measurement (the market predominantly offers 18mm and 20mm) clearly identifies this model. Verify compatibility by inserting a measuring tape between the lugs: the strap must fit without lateral play.

Natural alligator leather represents the finest choice, as its geometric texture dialogues perfectly with the sharp edges of the stainless steel case. A reliable alternative is calfskin with vegetable tanning, which develops a natural patina ageing parallel to the case. A stainless steel deployante clasp completes the material coherence.

The operation is straightforward: use a small hammer with a rounded tip or a dedicated tool to extract the spring bars from the lugs. Align the new strap's holes with the lugs and reinsert the bars until they click. Ensure the strap is precisely 19mm wide to avoid lateral movement.

Yes, provided the strap is dimensioned at 19 millimetres lug width. Bespoke artisanal straps guarantee perfect compatibility and allow you to choose material, colour and clasp finish according to your preferences. Quality aftermarket straps often exceed originals in comfort and aesthetics.

A premium leather strap, with vegetable tanning or alligator grain, maintains functional integrity for 3 to 5 years with daily use, depending on humidity, sun exposure and maintenance. Conditioning the leather every 6–12 months and avoiding prolonged contact with salt water extends longevity. Casati Milano provides an 18-month guarantee on all bespoke straps.
