Strap for Supermarine S500 Blue Bracelet

The lug width (ansa width) of the Bremont Supermarine S500BLbr is 22mm. This measurement, critical for strap compatibility, is taken from the outer edges of the lug holes through which the spring bar passes. On watches of this category (43mm, sports-oriented), 22mm represents the equilibrium point between case mass and the proportional aesthetics of the strap.

For the Bremont Supermarine S500BLbr, we recommend three complementary profiles: navy blue alligator for formal elegance, vegetable-tanned Tuscan calfskin (brown or cognac) for daily-classical wear, and a NATO in cordura or FKM rubber strap for intensive aquatic environments. Choice depends on use-case: calfskin offers aesthetic and tactile versatility, alligator creates sophisticated monochromy, technical straps guarantee absolute water-resistance and simplified maintenance.

Strap replacement is performed by removing the spring bar (perno passante) using a dedicated tool (spring bar removal tool) inserted into the lateral hole of the lug. Extract the bar, slide off the worn strap, and insert the new one by aligning the lug seats. The process demands care to avoid scratching the case: work on a soft cloth or entrust the task to a qualified watchmaker. On Bremont cases, the area surrounding the lugs is particularly refined—microabrasion risk is real.

Yes, any strap with a 22mm lug width is compatible with the Bremont Supermarine S500BLbr. Milano Straps offers a specialised collection of 22mm straps in vegetable leather, alligator, shell cordovan, NATO fabrics and FKM rubber, all tested for durability and finishing. Quality aftermarket straps maintain the watch's hydrostatic certification, provided you avoid using a strap with a heavy metal deployante buckle on non-reinforced lugs.

A high-quality leather strap (Tuscan calfskin, alligator) subjected to moderate-to-intensive use lasts 18–36 months before showing critical wear (tearing, excessive stiffness in the bend zone). Frequent exposure to salt water, chlorine or perspiration accelerates deterioration, reducing durability to 12–18 months. Technical straps in FKM or NATO have longer lifecycles (36–60 months) because they do not degrade biologically. Maintenance with specialist leather conditioners significantly extends longevity.
