Frequently asked questions

What is the lug width of the Tudor Style 12103-0003?

The lug width of the Tudor Style 12103-0003 is 20 millimetres. This measurement represents the distance between the two lugs that attach the case to the strap and is essential for aftermarket strap compatibility. Any strap for this model must have an internal opening of exactly 20mm to fit correctly into the lugs.

What is the best strap for the Tudor Style 12103-0003?

The ideal strap depends on intended use. For formal contexts, we recommend alligator in cognac tones or shell cordovan in dark brown, both capable of enhancing the case's minimalist elegance. For versatile daily wear, a vegetable-tanned calfskin in natural brown offers perfect balance between aesthetics and practicality. For those seeking a sporty solution, a grey or beige NATO maintains the model's sophistication.

How do you change the strap on the Tudor Style 12103-0003?

Strap replacement requires a dedicated tool (spring bar tool) or soft plastic stick. Position the watch on a flat surface and insert the tool's tip near the lug spring, applying gentle downward pressure to retract the spring, then extract the pin from the lug. Repeat on the other side. Insert the pin into the new strap, align properly and allow the spring to close naturally. Exercise caution to avoid scratching the case.

Is an aftermarket strap from another brand compatible with the Tudor Style 12103-0003?

Yes, any premium-brand strap (Molequin, Camille Fournet, Hirsch and others) with a 20-millimetre internal opening is compatible with the Tudor Style 12103-0003. Compatibility depends solely on lug width, not strap brand. We recommend selecting manufacturers that guarantee construction quality and finishes coherent with the Tudor model's elegance.

How long does a leather strap last on the Tudor Style 12103-0003?

Leather strap durability varies significantly based on material, usage intensity and maintenance. High-quality alligator or shell cordovan can last 5-7 years of daily use whilst maintaining good structural integrity. Calfskin, being more porous, tends to wear faster (3-5 years). Replacement is advisable when leather begins showing signs of deterioration at the eyelet holes or excessive flexibility. NATO straps, constructed from nylon, can last indefinitely if washed regularly.
