Frequently asked questions
What is the lug width of the Tudor Style 12310-0003?
The Tudor Style 12310-0003 is equipped with a lug width of 20mm. This measurement provides considerable versatility in strap selection whilst maintaining proportional balance between the 34mm case and the strap itself. To verify compatibility, measure precisely the internal space between the lugs using a digital calliper, ensuring the strap sits securely without any gaps.
Which strap is best suited to the Tudor Style 12310-0003?
For the 12310-0003, we recommend alligator leather with vegetable tanning in dark tones (cognac brown, black, navy blue) for formal elegance, or premium shell cordovan for those seeking material density and natural patina development over time. Vegetable-tanned calf leather offers a compromise between suppleness and formality. For summer contexts, NATO straps in fine-pettined fabrics maintain stylistic equilibrium whilst offering versatility.
How do you change the strap on a Tudor Style 12310-0003?
The strap change on the 12310-0003 is accomplished via the spring bars located beneath the lugs. Use a dedicated spring bar tool (small screwdriver with slot), inserting the tip into the lateral slot of the spring bar and pressing gently outward. Once the spring bar is freed, the strap slides away easily. Insert the new strap, aligning the holes with the lugs, then reinsert the spring bar until you hear the click of closure. For risk-free practice, we recommend the detailed guide available on our website.
Can I use an aftermarket compatible strap on the Tudor Style 12310-0003?
Absolutely. The 12310-0003, with its 20mm lug width, accepts any 20mm strap of artisanal quality. Aftermarket straps allow you to personalise your watch entirely according to your style and seasonal needs. We recommend choosing noble leathers (alligator, shell cordovan, vegetable-tanned calf) and manufacturers that guarantee fixed-point stitching and stainless steel spring bars for durability over time.
How long does a leather strap last on a Tudor Style 12310-0003?
A quality leather strap (alligatore or shell cordovan with vegetable tanning) has an estimated lifespan of 3 to 5 years with daily use before replacement is required. Factors such as ambient humidity, frequency of use, sun exposure and leather care influence longevity. To extend lifespan, occasionally apply natural leather balms and store your watch in dry environments. NATO and rubber straps offer superior durability, up to 7-10 years, but less formal elegance compared to noble leathers.
