Frequently asked questions

What is the lug width of the Tudor Style 12310-0030?

The lug width of the Tudor Style 12310-0030 is exactly 20 millimetres. This measurement represents the distance between the suspension pins of the case and is the fundamental parameter for selecting compatible aftermarket straps. It is sufficient to measure from pin to pin in the lug area with a digital calliper to verify this specification.

Which strap is best suited to the Tudor Style 12310-0030?

The ideal strap depends on the intended use. For formal contexts, alligator leather with vegetable tanning or smooth calfskin is recommended, as these enhance the inherent elegance of the model. For everyday wear, a cotton or linen NATO offers practicality and versatility. Those seeking a rich patina over time may choose shell cordovan, an exceptionally noble leather. The colour choice should harmonise with the stainless steel case.

How do I change the strap on the Tudor Style 12310-0030?

Strap replacement requires a spring bar tool (a specific tool for pin removal). Position the tool beneath the suspension pin and gently press to free it, then remove the original strap. Align the new strap holes with the case ends and reinsert the pin. It is important that the pin clicks into the correct position to ensure security.

Can I use an aftermarket strap compatible with the Tudor Style 12310-0030?

Absolutely. Thanks to the standardised 20-millimetre lug width, the Tudor Style is compatible with any aftermarket strap of the same width. milanostraps.it offers a wide selection of customisable straps in premium materials including alligator, calfskin, shell cordovan, cotton and rubber, all tested to ensure comfort and durability on this model.

How long does a leather strap last on a Tudor Style 12310-0030?

The lifespan of a leather strap depends on frequency of use, exposure to moisture and material quality. An alligator strap with vegetable tanning, if properly maintained, can last 5-7 years in daily use. Calfskin tends to degrade more quickly (3-4 years), whilst shell cordovan, being the densest leather, can reach 8-10 years. Regular maintenance with specialised creams significantly extends the strap's useful life.
