Strap for Bridgeport Automatic Ladies MOP

The lug width of the Tissot Bridgeport T045.207.11.113.00 is precisely 14mm. This measurement represents the internal distance between the two lugs where the strap is attached. You can verify this by measuring with a digital calliper between the lugs, or by consulting the official Tissot technical documentation. Swiss manufacturing tolerance maintains this dimension within ±0.2mm.

The ideal strap depends on your intended use. For daily elegance, we recommend vegetable-tanned calf leather with a caramelising patina over time. For formal occasions, shell cordovan provides constructive rigidity and tactile sophistication. For versatility and moisture resistance, NATO straps in polyamide are excellent performers. FKM rubber is the choice for high-exposure environments with detergents and dirt. All 14mm straps are fully compatible with your Bridgeport's lugs.

Changing the Bridgeport's strap requires a specific tool: a spring bar punch tool or extractor. Position the tool in the small lateral hole of the spring bar connecting the strap to the lug, apply gentle downward pressure, and pull the strap carefully outward. Repeat on the opposite side. Install the new strap by reversing the procedure. If you do not possess this tool, consult a qualified watchmaker or visit Casati Milano atelier for professional strap replacement.

The original Tissot strap offers certified construction warranty and compatibility, but provides limited colour and material options. A bespoke aftermarket 14mm strap permits aesthetic personalisation—choice of leather (alligator, shell cordovan, calf), exclusive colours, particular finishes—whilst maintaining full mechanical compatibility. A bespoke artisanal strap can exceed original quality in terms of aesthetic ageing and tactile comfort, though it requires conscious maintenance.

A vegetable-tanned leather strap has a typical lifespan of 4-7 years with moderate daily use, variable according to exposure to moisture, perspiration and detergents. Tannin-treated leather ages visibly, developing a dark patina that is an aesthetically desirable characteristic among collectors. To extend durability, periodically apply a protective natural oil (mink oil) and avoid prolonged water immersion. Shell cordovan has superior durability (8-12 years) due to its constructive density. NATO polyamide straps last indefinitely without aesthetic deterioration.
