Strap for Style 34 Stainless Steel / Fluted / Blue-Diamond / Strap

The Tudor Style 12310-0029 features a precisely measured 20mm lug width, proportionally calibrated to the 34mm case diameter. This dimension reflects Tudor's design philosophy for this collection and ensures full compatibility with standard 20mm watch straps across the horology market.

Natural alligator with medium patina represents the formal choice, emphasising the case's understated aesthetic. For versatile daily wear, vegetable-tanned calf leather develops personalised patina over time. Shell cordovan is recommended for those seeking structural longevity and deep patina without intensive maintenance. For informal contexts, NATO fabric and synthetic FKM rubber ensure water resistance and abrasion durability.

Strap replacement requires removal of the spring bars securing the lug holes to the previous strap. Use a dedicated spring bar tool or small flathead screwdriver to compress the internal spring and extract the pin from its seat. Once removed, the old strap releases easily. Position the new 20mm strap at the lugs and reinsert the spring bars, verifying correct anchoring on both case sides.

Yes, any strap with a 20mm lug width is compatible with the 12310-0029. This universal specification allows selection from an extensive range of aftermarket straps in leather, fabric, rubber and metal. Ensure the chosen strap has no constructive excesses at the terminals that might cause friction against the case flanks.

Longevity depends on leather type and wearing frequency. A vegetable-tanned calf strap develops visible wear (though not structural failure) after 2-3 years of daily use, with potential service life of 5-7 years. Shell cordovan offers superior resistance, maintaining structural integrity for 10-12 years. Natural alligator, if not exposed to excessive moisture, retains elasticity for 6-8 years. Periodic maintenance with specialist creams extends any natural leather strap's lifespan significantly.
