The Style 12510-0025 (aka: M12510-0025), seen from the bench

The Tudor Style M12510-0025 is a contemporary dress watch featuring a 38mm stainless steel case with brushed finish and integrated bracelet. Powered by the automatic Tudor T601 calibre, it displays hours, minutes, seconds, and date. The 20mm lug width accommodates standard watch straps, maintaining formal proportions suited to the Swiss watchmaking heritage. The case develops a natural patina over time while ensuring daily reliability and water resistance.

Frequently asked questions

What is the lug width of the Tudor Style 12510-0025?

The lug width of the Tudor Style 12510-0025 is 20mm. This measurement represents the distance between the case lugs and determines compatibility with aftermarket straps. You can verify it by measuring the lug-to-lug distance with callipers, or by consulting Tudor's official technical specifications.

Which strap pairs best with the Tudor Style 12510-0025?

We recommend a dark brown alligator strap or cognac shell cordovan for the Tudor Style 12510-0025. These materials emphasize the dress watch's formal character and create a natural aesthetic dialogue with the patina developing on the stainless steel case. Alternatively, vegetable-tanned calf leather offers durability and controlled ageing whilst maintaining stylistic coherence.

How do I change the strap on the Tudor Style 12510-0025?

Remove the original strap by carefully opening the spring bar pins with a spring bar tool, applying downward pressure to release the internal spring. Insert the new 20mm strap in the same manner, verifying that the pins are fully locked in place. If inexperienced, entrust the operation to a professional to prevent case damage.

Can I use aftermarket straps on this model?

Yes, any strap with a 20mm lug width is compatible with the Tudor Style 12510-0025. Milanostraps offers a selection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm artisanal straps</a> customisable in leather, colour and length. The Casati Milano atelier also creates bespoke straps with an 18-month guarantee.

How long does a natural leather strap last on the Tudor Style 12510-0025?

A quality natural leather strap (alligator, shell cordovan or vegetable-tanned calf) lasts an average of 5-7 years with daily use and proper maintenance. Longevity increases if the strap is rotated among multiple watches and regularly treated with specialised products. Excessive moisture and direct sun exposure reduce the lifespan of natural leather.
