The Style 12310-0028 (aka: M12310-0028), seen from the bench

The Tudor Style 12310-0028 is a 34mm stainless steel watch featuring the T601 automatic caliber with hours, minutes, seconds and date. Launched as a modern evolution of classic Tudor Sport models, this compact case design reflects 1970s–1980s proportions and refuses contemporary size inflation. The 20mm lug width ensures visual and structural balance on the wrist, combining geometric elegance with functional simplicity.

Frequently asked questions

What is the lug width of the Tudor Style 12310-0028?

The lug width of the Tudor Style 12310-0028 is precisely 20mm. This measurement represents the distance between the case lugs where the strap is attached. It is essential to verify this dimension before ordering an aftermarket strap, as even minor variations compromise compatibility and wearing comfort.

Which strap is best suited for the Tudor Style 12310-0028?

For the 12310-0028, we recommend premium leathers such as medium brown alligator, vegetable-tanned calf, or shell cordovan. These materials enhance the minimalist aesthetics of the 34mm case and develop a patina that improves with time. For sporting use, certified cotton NATO straps or FKM rubber offer practicality without visual compromise.

How do you correctly change the strap on a Tudor Style?

To change the strap, position the watch on a soft surface and use a spring bar removal tool to gently push the elastic pin towards the inside of the case. Once tension is released, the pin slides out and frees the strap. Install the new strap by reversing the procedure, ensuring the spring bar clicks firmly into its seats.

Is an aftermarket 20mm strap fully compatible with the 12310-0028?

Yes, any strap with a 20mm lug width is mechanically compatible. However, for optimal aesthetic results, consider the leather thickness (3.5-4mm recommended) and total strap length, which must cover the wrist with a minimum range of 2cm. Artisanal aftermarket straps also allow personalised length adjustment.

How long does a leather strap last on a watch like the 12310-0028?

A premium leather strap (alligator, cordovan, or vegetable-tanned calf) typically lasts 3-5 years of daily use, with variability depending on the type of tanning and exposure conditions (perspiration, humidity, UV rays). Shell cordovan tends to last longer due to its structural density. Regular maintenance – cleaning with a soft cloth and occasional hydration with a specific balm – significantly extends longevity.
