Strap for Style 28 Stainless Steel / Yellow Gold / Black-Diamond / Strap

The lug width of the Tudor Style 12103-0012 is 20 millimetres. This measurement represents the distance between the centres of the two lateral lugs on the case and is the fundamental parameter for selecting a compatible strap. An incorrect measurement would result in an ill-fitting or overly tight strap.

For the Tudor Style 12103-0012, an alligator strap in cognac or black is the most refined choice, as the fine grain of the leather visually enhances the two-tone yellow gold and stainless steel case. Alternatively, a smooth calf leather strap in tobacco brown offers superior versatility and durability, ideal for daily wear without aesthetic compromise.

To change the strap, remove the lug pins using a spring bar tool. Position the watch dial-down, insert the flat end of the tool into the lug hole and press gently to release the pin from its seat. Repeat for both lugs, then insert the new strap in reverse order.

Yes, you may use aftermarket straps provided they have a lug width of exactly 20 millimetres. High-quality artisan straps crafted from premium leather such as alligator or shell cordovan offer a significant aesthetic and tactile upgrade over original straps while maintaining full case compatibility.

Strap longevity depends on material and usage: a smooth calf strap typically lasts 4–6 years with regular maintenance; alligator and shell cordovan, owing to more robust fibrous structure, can endure 7–10 years or beyond. Preventative maintenance—periodic hydration with specialist creams and protection from excess humidity—significantly extends strap lifespan.
