Frequently asked questions

What is the lug width of the Tudor Style 12303-0009?

The Tudor Style 12303-0009 features a lug width of 20 millimetres. This specific measurement refers to the distance between the two lugs (attachment points) of the case where the strap is secured via the passants. It is essential to verify this measurement before purchasing a replacement strap to ensure proper fit to the case.

Which strap is recommended for the Tudor Style 12303-0009?

For the Tudor Style 12303-0009, the ideal choice is an alligator strap in dark brown or tobacco, which enhances the yellow gold inlays of the two-tone case. Alternatively, a black or cognac calf leather offers excellent versatility in both formal and everyday contexts. MilanoStraps offers a curated collection of 20mm straps specifically calibrated for this model.

How do you change the strap on the Tudor Style 12303-0009?

To change the strap on the 12303-0009, you need a spring bar tool—a specialised instrument with a metal hook—to compress the springs hidden at the base of the case lugs. Once the springs are depressed, the strap passants will detach easily. Proceed with extreme care to avoid scratching the polished case, particularly the yellow gold inlays.

Is an aftermarket strap compatible with the Tudor Style 12303-0009?

Yes, any strap equipped with 20mm passants is fully compatible with the Tudor Style 12303-0009. MilanoStraps offers a selection of 20mm straps of artisanal quality, available in various materials and finishes, customisable in measurements, initials and type of stitching thread.

What is the average lifespan of a leather strap for the Tudor Style 12303-0009?

The lifespan of a leather strap depends on construction quality and conditions of use. A high-quality alligator or vegetable-tanned calf strap can last between 3 to 5 years with proper maintenance (avoid prolonged exposure to excessive moisture and heat). A shell cordovan strap, thanks to its exceptional durability, can exceed 7 years. MilanoStraps guarantees 18 months on straps crafted at the Casati Milano atelier.
