Frequently asked questions

What is the lug width of the Tudor Style 12310-0017?

The Tudor Style 12310-0017 features a 20mm lug width. This measurement represents the distance between the two attachment pins on the case and determines which strap is compatible. To verify this measurement on your watch, use a digital calliper and measure from the outer edge of one pin to the outer edge of the other.

Which strap material is best suited for the Tudor Style 12310-0017?

The ideal material depends on your intended use. For formal occasions, we recommend a black or brown alligator strap, which emphasises the model's minimalist character. For a versatile approach, vegetable-tanned leather represents the most conscious choice, developing character over time. For sporty or casual situations, rubber or NATO straps offer practicality without aesthetic compromise.

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

To change the strap, obtain a spring bar removal tool with a double-ended tip. Insert one tip under the pin protruding from the case, applying gentle upward pressure. The pin will retract, allowing you to remove the old strap. Align the new strap's pins with the case lugs and press until you hear an audible click. Verify that the strap is completely secured.

Are aftermarket straps compatible with the Tudor Style 12310-0017?

Yes, any strap with a 20mm lug width is compatible with the 12310-0017. Artisanal quality straps offer superior finishing compared to original straps, with personalisation options: leather choice (alligator, calf, shell cordovan), colour tone, strap width, stitch thread colour, and embroidered initials.

How long does a natural leather strap last?

The lifespan of a leather strap depends on usage, climate, and material quality. A vegetable-tanned artisanal leather strap, worn daily, typically lasts 3 to 5 years. The ageing process is part of the beauty: the leather develops a natural patina that deepens over time. With careful maintenance (avoiding prolonged immersion, drying quickly if wet), the lifespan can extend to 7 years.
