Strap for Conquest Automatic 39

The lug width is 19 mm, measured between the interior edges of the lugs. You need straps specifically sized at 19 mm, not 20 mm, to avoid visible lateral play and ensure secure attachment. The strap thickness must remain under 4.5 mm to fit properly within the case lugs.

The choice depends on intended use: for formal contexts, authentic alligator amplifies sophistication; for everyday versatility, vegetable-tanned calf develops beautiful patina over time; for aquatic environments, rubber or shell cordovan offer maximum durability and moisture resistance. A nylon NATO strap maintains the watch's sporting heritage.

The change requires a small flat tool (spring bar tool) to gently remove the spring bars from the lugs. Position the tool in the small side hole of each bar, gently compress the internal spring, and slide the bar end out of the lug. Repeat on both sides, then insert the bars into the new strap using the reverse procedure.

Yes, any 19 mm strap with thickness under 4.5 mm is compatible. Verify that the spring bars are robust (316L stainless steel) and the strap is professionally manufactured to avoid stitch detachment or poor craftsmanship. Artisanal Italian straps ensure superior standards compared to mass production.

An alligator or shell cordovan strap, with proper maintenance and periodic rotation, lasts 10–15 years of continuous use. A vegetable-tanned calf strap resists 5–8 years under normal conditions, less if frequently exposed to humidity, chlorine, or intense perspiration. Longevity increases significantly if the strap receives annual professional maintenance (cleaning, conditioning, stitch inspection).
