Strap for Conquest 34 Stainless Steel / Mint Green / Rubber

The lug width of the L3.430.4.02.9 is 17mm. This measurement should be verified with a digital calliper, measuring from the inner edge of one spring bar tube to the other. A measurement error causes friction and damages the strap over time.

Black or deep brown alligator leather is the formal choice, enhancing the compact diameter without weighing down the wrist. Vegetable-tanned calf leather suits those desiring natural patina development. Cotton or silk NATO straps offer casual versatility. Natural rubber is recommended for high-humidity environments or intensive daily wear.

Position the watch face-down on a soft surface. Locate the spring bar tubes (metal shafts connecting the lugs). Use a spring bar tool to compress the internal spring and slide the tube horizontally from its seat. Repeat on the opposite lug. Insert the new strap, aligning the spring bar tube with the seat, and release the spring. Verify symmetrical seating.

No. An 18mm strap will not fit: the lug is only 17mm wide. Forcing it risks stress damage to both the lug and buckle. The sole exception is a width-adjustable strap (rare and expensive). Always verify compatibility before purchase.

A quality artisanal alligator or calf strap lasts 18–36 months with daily wear and proper care (periodic cleaning, drying, avoiding prolonged moisture). Vegetable-tanned leather typically outlasts chrome-tanned variants because the fibres retain elasticity. Shell cordovan, if available, exceeds 4 years. Lifespan varies with climate and frequency of wear.
