Strap for Conquest 38 Stainless Steel / Champagne / Bracelet

The lug width of the Longines Conquest L3.720.4.62.6 is 19mm, measured from the inner wall of one lug to the opposite side. This non-standard width makes the model an excellent candidate for bespoke strap commissions.

Chrome-tanned calf and alligator leather are technically optimal: calf offers daily resilience and fine grain texture; alligator delivers pronounced surface character and patina evolution. For natural tannage aficionados, shell cordovan combines structural durability with intrinsic lustre.

Remove the spring bars connecting the strap to the lugs using a dedicated spring bar tool, avoiding contact with the case. Align the new strap's holes with the spring bars and press until they lock automatically in place.

Yes. Any strap sized at 19mm lug width is compatible with the Conquest L3.720.4.62.6. Ensure the base width accommodates the lug height to prevent lateral tension that would degrade the buckle and case shoulders over time.

A quality leather strap (calf, alligator, shell cordovan) will perform reliably for 18–36 months under daily wear, depending on frequency, climate exposure and moisture. Chrome-tanned skins require replacement when the buckle begins separating from its base; vegetable-tanned leather develops evolutionary patina, extending aesthetic appeal.
