Frequently asked questions
What is the lug width of the Tudor Style 12310-0013?
The lug width of the Tudor Style 12310-0013 is 20mm. This measurement refers to the distance between the two lateral pins that attach the case to the strap. Verifying this dimension before purchasing an aftermarket strap is essential to ensure perfect compatibility and correct positioning without lateral play.
Which strap is best suited for the Tudor Style 12310-0013?
The ideal strap depends on intended use. For formal and business contexts, we recommend alligator or calf leather with vegetable tanning, which enhance the elegance of the 34mm case. For a versatile profile, calf leather is optimal thanks to its softness and the personalised patina it develops over time. For sportier or casual settings, NATO fabric or FKM rubber straps offer practicality and moisture resistance.
How do I change the strap on my Tudor Style 12310-0013?
To change the strap you will need: a spring bar tool or small pliers, the new 20mm strap, and good lighting. Position the watch face down on a soft surface, locate the lateral pin (metal rod passing through the strap holes), gently push the pin outward with the spring bar tool until it slides out, remove the old strap and insert the new one, aligning the holes. Ensure the pin is correctly seated in both case lugs.
Is an aftermarket strap compatible with the 12310-0013?
Yes, any strap with a 20mm lug width is compatible with the Tudor Style 12310-0013. Quality aftermarket straps offer the same construction precision as original straps. Verify that the strap is made with certified materials (vegetable-tanned leather, genuine alligator, robust fabrics) and that the stitching is regular and consistent. Compatibility is determined by lug width, not by brand.
How long does a leather strap last over time?
The lifespan of a leather strap depends on intensity of use, climate conditions and material. A calf leather strap with vegetable tanning, worn daily under normal conditions, typically lasts 2-3 years before requiring replacement. Alligator, being more robust, can reach 4-5 years. Visible ageing (patina, colour change) does not indicate functional deterioration but rather aesthetic enrichment. Rubber or fabric straps have similar lifespans, but with less evident degradation and more uniform ageing.
