Strap for Elegant Collection 25.5 Automatic Stainless Steel / Red Gold / Diamond / MOP

The lug width of the Longines Elegant L4.309.5.88.7 is 13 mm. This dimension represents the perpendicular distance between the two metal lugs protruding from the case and is essential for selecting a compatible strap. Measuring the lugs with a digital calliper provides the precise specification needed to order a bespoke strap.

For a dress watch of 25.5 mm such as the Elegant, we recommend alligator or shell cordovan in dark tones (black, brown, cognac). Alligator maintains natural aesthetic continuity and ages by developing a patina that mirrors the steel case. Shell cordovan offers superior structural rigidity and a lustre that requires no finishing. For afternoon wear, vegetable-tanned calfskin in tobacco tones introduces controlled chromatic warmth.

Strap replacement requires a specialised tool (spring bar tool) to compress the internal springs that held the previous strap to the case lugs. It is advisable to consult a qualified watchmaker or the artisans at Casati Milano to avoid micro-scratches on the case. The procedure takes 10-15 minutes and causes no damage if executed properly.

Yes, any strap with a 13 mm lug width is technically compatible. However, the construction quality of the aftermarket strap determines final durability and aesthetics. We recommend artisanally crafted straps in premium leathers (Nile alligator, shell cordovan, vegetable-tanned calfskin) rather than industrially produced straps, which tend to deteriorate rapidly.

A premium leather strap crafted artisanally, such as those offered by Casati Milano, typically lasts 3-4 years under regular wear (5 days per week). Longevity depends on leather type: alligator and shell cordovan resist deterioration longer than ordinary calfskin. Perspiration, solar exposure and neglect in maintenance significantly reduce strap lifespan. Periodic maintenance and cleaning with a damp cloth extend durability substantially.
