Strap for Aquaracer 500M Quartz 43 Stainless Steel / Black / Bracelet

The lug width is 20mm. This is the internal space between the integrated lugs of the case where the strap must be inserted. Always verify this measurement before purchasing an aftermarket strap, as an incorrect size would render the strap incompatible with your timepiece.

The ideal strap depends on your intended use. For formal elegance, we recommend dark blue alligator with a brushed steel deployante. For aquatic activities, a navy NATO or dark grey rubber offers maximum practicality. Vegetable-tanned leather represents the perfect compromise between aesthetics and durability, suitable for both office and casual environments.

Strap replacement is straightforward: locate the spring bars inside the case lugs. Using a springbar tool (a specific two-pronged instrument), gently press the lower bar and extract it from the lug. Repeat on the other side. Position the new strap in the lug and reinsert the spring bars until they click into place. Avoid forcing to prevent lug damage.
