Strap for Supermarine S500

The Bremont Supermarine S500BK features a lug width of 22mm. This dimension is measured as the internal space between the two spring bars connecting the strap to the case. To verify, remove the original strap and measure the gap: it must correspond exactly to 22mm. This standard lug width is typical for high-end tool watches and ensures harmonious proportions with the 43mm case.

For the S500BK, we recommend alligator straps with vegetable tanning in dark brown, which emphasise the contrast with the steel and black dial. Alternatively, shell cordovan with its waxy patina offers austere elegance. If you seek comfort and versatility, vegetable-tanned black leather with cream stitching is both noble and practical. For functionality and water resistance during diving, vulcanised FKM rubber straps are the ideal choice for aquatic environments and extreme operations.

To change the S500BK strap, use a spring bar tool or dedicated remover to gently push the elastic pins inward. The caseback is press-fitted, so work on a clean surface. Insert the new strap by aligning the pins with the lugs and verify they click securely into position. Never force the pins: smooth, controlled movement ensures maximum case security and prevents damage to the spring bar mechanisms.

Yes, aftermarket straps are compatible provided they have the exact 22mm lug width. Before purchase, always verify this dimension with your retailer. Quality straps, such as those in vegetable alligator or shell cordovan, maintain aesthetic and durability standards compatible with the watch. Avoid budget straps that could compromise the watch's appearance and water resistance integrity.

A quality leather strap, such as vegetable-tanned alligator or shell cordovan, can last 3–5 years with daily wear if subjected to regular maintenance. Replacement frequency depends on exposure to moisture, perspiration, and sunlight. Straps frequently exposed to water (such as during diving operations) require more frequent replacement. To extend strap life, avoid prolonged humidity exposure and clean regularly with soft, dry cloths.
