Frequently asked questions

What is the lug width of the Bremont Supermarine S500SIbr?

The Bremont Supermarine S500SIbr features a lug width of 22 millimetres. This standard is typical of 43mm sports watches of British and German make, and accommodates straps of robust thickness necessary for a chronograph designed to withstand torsional stress and abrasion. All straps available on Milano Straps in the 22mm category are perfectly compatible with this model.

Which strap is best for the Bremont Supermarine S500SIbr?

There is no absolute choice, but three pairing profiles: alligator with vegetable tanning represents the classical option, with structured grain that dialogues elegantly with the satin surfaces of the case and develops a caramel patina over time; premium cotton-polyester NATO offers versatility and maintenance-free wear; FKM rubber remains ideal for humid environments and genuine diving, resists rot and maintains elasticity in cold water. For urban context, Italian shell cordovan offers notable perceptual upgrade with development of characteristic creasing over time.

How do you change the strap on a Bremont Supermarine S500SIbr?

The S500SIbr features two straight lugs made entirely of stainless steel with curves following the case geometry. To remove the strap, a spring bar tool is required: position the curved tip beneath the pin from the dial side, apply inward pressure, extract the pin from its seat. Repeat for both sides. Installation of the new strap follows the reverse procedure: align the strap holes with the lugs, reinsert the pins, verify they are firmly seated.

Are there aftermarket straps compatible with the Bremont Supermarine S500SIbr?

Yes, any strap with a 22mm lug width is compatible with the S500SIbr. Milano Straps offers a carefully curated selection of straps calibrated for this width in various materials: alligator with vegetable tanning, calf box with deployante, premium NATO, FKM rubber. All guarantee perfect compatibility and finishing of the spring bars in harmony with the aesthetic code of the watch.

How long does a leather strap last on a Bremont Supermarine S500SIbr?

Durability depends on tanning and material: an alligator strap with vegetable tanning, subjected to correct use and minimal maintenance (periodic cleaning with soft cloth, exposure to sunlight for natural oxidation), maintains functionality and aesthetics for 8-12 years. Shell cordovan, owing to fibre density, can extend this window to 15+ years. Calf box achieves 6-8 years. FKM rubber, devoid of biological degradation, far exceeds these periods. Factors such as ambient humidity, continuous direct sunlight exposure and frequent solvent contact accelerate ageing.
