Strap for Conquest Classic Automatic 29.5 Stainless Steel / Black / Strap

The lug width of the Longines Conquest Classic L2.285.4.58.3 is 20 mm. This measurement represents the distance between the two metal pins that protrude laterally from the case. It is essential to verify this dimension before purchasing an aftermarket strap to ensure proper fit and compatibility without forcing.

For the Conquest Classic L2.285.4.58.3, alligator straps in vegetable tanning represent the most harmonious solution: the rectangular grain of the species naturally dialogues with the case proportions without introducing competing visual elements. Shell cordovan offers a formal alternative with dense structure and characteristic patina, whilst calfskin provides chromatic versatility and immediate softness. NATO straps in woven fabric allow a versatile sport-oriented interpretation.

Strap replacement involves removing the metal pins from the lugs using a spring bar tool (a specialized instrument equipped with two flat ends). Insert the tool into the small lateral hole of the lug to release the tension of the pin's internal spring, then extract the pin. Repeat for both sides. Insert the new pins into the prepared strap and position the strap between the case lugs, allowing the pins to snap into the housings. This operation is advisable at an authorised service centre or at the Casati Milano atelier to prevent case damage.

The lifespan of a leather strap depends on intensity of wear, climatic conditions and material choice. A good quality alligator or shell cordovan strap, subject to moderate daily use and proper maintenance (periodic drying, protection from excessive humidity), can last 5-7 years before requiring replacement. Calfskin straps, structurally less dense, tend to wear more rapidly (3-5 years). Proper storage in humidity-controlled environments significantly extends longevity. The Casati Milano atelier applies an 18-month guarantee on custom-made straps.
