Strap for Prestige Rattrapante Yellow Gold / White

The lug width of the Longines Les Grandes Classiques L4.654.6.11.2 is 20mm. This measurement is standard for 38mm-diameter watches and is compatible with the entire collection of 20mm watch straps available on MilanoStraps, in both leather and rubber options.

The best strap depends on intended usage. For formal and evening occasions, we recommend black polished alligator with vegetable tanning, which develops a golden patina in harmony with the yellow gold case. For daily wear, an Italian calf leather with vegetable tanning in medium brown tones (Havana) offers the finest balance between aesthetics, durability and comfort. Shell cordovan is the choice for those seeking a piece that marks the passage of time with controlled creasing.

Strap replacement requires a specific tool: a spring bar tool or small forked rod. Position the watch on a soft surface, insert the tool beneath the metal pin (spring bar) connecting the strap to the case, gently lift until the pin retracts, then remove the old strap. Repeat on the other side. Installation of the new strap follows the reverse procedure: align the pin with the holes of the new leather, press until the pin locks into position. Atelier Casati Milano offers changing and personalisation services with direct consultation if you are uncertain about the procedure.

Yes, this is entirely possible and recommended. Quality aftermarket straps, such as those available on MilanoStraps in the 20mm size, have been specifically tested for mechanical and aesthetic compatibility with watches in this category. The 20mm lug width is the industry standard for this case size. We recommend verifying that the strap features high-quality spring bars (stainless steel or titanium) to ensure longevity and security of attachment.

The lifespan of a leather strap varies based on material, daily usage and maintenance. A superior quality Italian calf leather with vegetable tanning lasts an average of 3-5 years with moderate use (not daily wear). Alligator, thanks to its naturally firmer structure, can exceed 7 years. Shell cordovan, the most resistant, can last 10 years or more. Regular maintenance—cleaning with a damp cloth and occasional treatment with leather-specific creams—significantly extends useful life. Atelier Casati Milano provides 18-month warranty on all bespoke straps and offers restoration and regeneration services to further extend the life of the piece.
