Frequently asked questions

What is the lug width of the Tudor Style 12100-0015?

The lug width of the Tudor Style 12100-0015 is 20 millimetres. This measurement is essential when purchasing a compatible strap. You can measure it by placing a digital calliper on the internal distance between the two case lugs.

Which strap is most suitable for the Tudor Style 12100-0015?

For the Tudor Style 12100-0015, we recommend black or dark brown alligator for formal wear, vegetable-tanned calf leather for daily comfort, or shell cordovan for sartorial elegance. If you prefer practicality, a dark grey NATO strap maintains the dress-watch character of the model.

How do I change the strap on my Tudor Style 12100-0015?

To change the strap, remove the watch from your wrist and locate the two lateral pins that secure the bracelet to the case. Use a dedicated spring bar tool to compress the internal springs of the pins, extracting them gently. Insert the new strap, aligning the holes with the case guides, and reinsert the pins until they click into place.

Can I use an aftermarket compatible strap on my Tudor Style 12100-0015?

Yes, absolutely. As long as the strap has a 20mm lug width, it is compatible with the Tudor Style 12100-0015. Artisanal straps in alligator, calf leather, or shell cordovan offer superior aesthetic flexibility and personalisation compared to the original bracelet.

How long does a leather strap last on the Tudor Style 12100-0015?

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with regular daily use. Durability depends on the tanning process, ambient humidity, and maintenance. An 18-month warranty is standard for professional artisanal straps, although natural leather ages and develops patina even beyond this period.
