Strap for Conquest 39 Automatic Silver

The lug width of this model is 19 mm. This is the vertical space between the two lugs (case protrusions) where the strap is attached. You can verify it by measuring the internal distance of the lugs with a digital calliper after removing the original strap.

There is no universally "best" strap—it depends on your usage. A dark brown alligator emphasises elegance and develops a beautiful patina over time. A vegetable-tanned calf offers daily durability and authentic ageing. A NATO cordura strap maintains the sports heritage. Choose alligator for formality, calf for versatility, NATO for casual robustness.

Use a spring bar removal tool to extract the spring bars from the case lugs. Position the tool in the lateral slot of each bar, press downward to compress the spring, then extract. Repeat on the other side. Align the new strap holes with the lugs, then reinsert the bars by compressing the springs until they click into place.

Yes, provided the lug width is exactly 19 mm. Any generic 19 mm strap, regardless of brand, fits correctly. Always verify the seller's specifications. Bespoke straps can be tailored to your exact length, stitching style and finishing for enhanced precision.

A quality leather strap (alligator or vegetable-tanned calf) lasts 3–5 years with daily wear, depending on sun exposure, humidity and cleaning frequency. Vegetable-tanned leather ages more gracefully than chemically-dyed straps. Regular maintenance—gentle cleaning and occasional waterproofing—significantly extends strap longevity.
