Strap for Conquest 35 Quartz Ceramic Diamond

The Longines Conquest L3.281.0.87.6 features a 17mm lug width. This measurement indicates the distance between the two holes through which the watch strap pins pass. Precision is essential: even a millimetre discrepancy will compromise fit. To verify, measure with a ruler from the centre of the left hole to the centre of the right hole on the watch case's lugs.

The choice depends on intended use and aesthetic preference. For dress-casual elegance, crocodile leather in brown or cognac complements the mother-of-pearl dial perfectly. For daily versatility and noble patina development, vegetable-tanned calf offers timeless character. For those appreciating unmatched material nobility, shell cordovan in wine tones delivers unparalleled lustre and density. For a sporty approach, a robust NATO strap or FKM rubber ensures practicality and contemporary appeal.

Changing the strap requires a dedicated spring bar removal tool. Position the watch face-down, insert the tool's tip into the small hole beneath the lug to lift the spring bar. The pin slides out automatically. Repeat on the opposite side. Insert the new strap's pins into the same holes and press until you feel the spring bar click into place. Avoid forcing: spring bars are precision components that demand care.

Absolutely. Any strap with pin holes spaced 17mm apart is compatible with the L3.281.0.87.6. Milanostraps produces bespoke leather straps—crocodile, calf, and shell cordovan—precisely calibrated for this lug width. Quality aftermarket straps frequently exceed the original in material excellence and craftsmanship, delivering superior tactile and visual experience.

A quality leather strap (crocodile, calf, shell cordovan) typically lasts 3–5 years with daily wear, longer with occasional use. Longevity depends on wear frequency, perspiration, humidity exposure, and tanning quality. Vegetable-tanned leather develops noble patina and can be rejuvenated. Shell cordovan is exceptionally durable. To extend lifespan, avoid prolonged water immersion and periodically apply a bespoke watch leather balm.
