Strap for Supermarine S500 Bracelet

The lug width of the Bremont Supermarine S500BKbr is 22mm. This dimension represents the distance between the two case lugs (horizontal pins) where the strap is attached. To verify it, measure the interior of the case with a digital calliper, measuring side-to-side from lug to lug. An aftermarket strap for this model must have exactly 22mm width to fit perfectly without lateral play or binding.

For a dive watch such as the Supermarine S500BKbr, we recommend a vegetable-tanned strap in Tuscan bruciato leather or calf leather with structured grain. Vegetable tanning develops natural patina over time, synchronising with the watch's operational history. If maximum durability in marine environments is your priority, an FKM rubber strap offers superior resistance to saltwater immersion. For more formal applications or contemporary aesthetics, alligator leather represents a refined alternative, though it is less resistant to salt humidity than vegetable-tanned leather.

Changing the strap on a Bremont Supermarine S500BKbr requires a spring bar remover tool. Position the watch with the case facing upward, insert the tip of the remover beneath the lug (the metal pin) and apply gentle downward pressure to release the spring retention. Repeat on the opposite side. Remove the old strap and insert the new one using the same procedure in reverse, ensuring the springs click securely into position. If you lack experience, consult a watchmaker to avoid damage to the case.

Yes, a 22mm strap is compatible with any timepiece possessing a 22mm lug width. This dimension is common across many dive watches, sports watches, and military-inspired models from various manufacturers. Before purchasing, always verify the exact lug width of your watch. Milano Straps offers an extensive catalogue of customisable 22mm straps suited to different use profiles and aesthetic preferences.

An artisanal vegetable-tanned strap, worn daily, has an average lifespan of 3 to 5 years before replacement becomes necessary. The natural patina that develops represents the mark of use and the wearer's bond with the watch. If exposed to constant moisture (repeated immersion, saltwater exposure), the lifespan decreases to 2 to 3 years. An FKM rubber strap has a superior lifespan of 5 to 7 years with intensive use and is better suited to aggressive marine environments. Regular maintenance with specialised leather conditioners extends the strap's service life.
