Strap for Style 34 Stainless Steel / Yellow Gold / Fluted / Silver / Strap

The lug width of the Tudor Style 12313-0018 is 20 millimetres. This is the precise distance between the lugs (the bars where the strap attaches to the case). It is essential to verify this measurement before purchasing an aftermarket strap, as even half a millimetre difference can result in incompatibility or a loose, unsafe fit.

For a dress watch of this calibre, alligator leather represents the finest choice: the natural grain texture and the elegance of the material complement the two-tone gold and steel case beautifully. Notable alternatives include shell cordovan, which offers natural rigidity and intrinsic lustre, and vegetable-tanned calf leather, which develops a refined patina over time. Ideal colours: chocolate brown, anthracite grey, dark burgundy, or black.

Changing the strap requires a spring bar tool to release the attachment pins. Place the watch face-down on a soft surface, insert the spring bar tool into the hole, and gently press to retract the pin. Once released, remove the old strap and insert the new one, aligning the pins in the attachment holes and ensuring they click securely into place. If you are unfamiliar with this procedure, entrust the task to a professional watchmaker.

No, a 20mm strap is specific to watches with a 20 millimetre lug width. Although this is a relatively common width, it is not universal: 34mm watches may have lugs measuring 18mm, 19mm, or even 22mm depending on the model. Always verify the precise lug width of your specific timepiece before ordering a replacement strap.

A high-quality leather strap—alligator, cordovan, or vegetable-tanned calf—typically lasts between 5 and 8 years with moderate daily use, provided it receives regular maintenance: periodic cleaning with a damp cloth and conditioning with watch-specific leather creams. Prolonged exposure to sunlight, moisture, and perspiration accelerates deterioration. Lower-quality straps may last only 2 to 3 years. A replacement represents an opportunity to refresh the aesthetic of your timepiece.
