Strap for Style 28 Stainless Steel / Silver-Diamond / Strap

The lug width of the Tudor Style 12100-0020 is 20mm, a consolidated standard in mid-to-high-end watchmaking. This dimension is critical when purchasing aftermarket straps: an incompatible lug width will not seat correctly in the case lugs, causing lateral play or mechanical resistance during strap rotation. Always verify the measurement with a digital calliper before purchase.

The choice depends on intended use and aesthetic preference. For formal wear: dark brown alligator or black shell cordovan. For daily versatility: vegetable-tanned calf in brown or burgundy tones, which develops natural patina over time. For humid environments or light sports: satin rubber Tropic strap. Our online 20mm straps are customisable in leather type, colour, width, and stitching thread.

Remove the watch from your wrist. Using a spring bar tool (with rounded ends), apply gentle vertical pressure on one of the case's lateral pins to release the internal spring tension. The strap will slide out easily. Reverse the procedure with the new strap, ensuring the pin is fully inserted into the case lugs before releasing pressure. Never use sharp implements (scissors, blades) as they will scratch the case finish.

Yes, any strap with 20mm lug width is mechanically compatible with the Tudor Style 12100-0020. However, construction quality varies significantly between manufacturers. Choose straps with external finishes consistent with your case (satin if case is satin, polished if polished) and verify that stitching is regular, thread is not frayed, and any metal elements (needle, buckle, keeper) are proportioned to the watch's compact dimensions.

Leather strap longevity depends on material type, usage patterns, and climate conditions. A quality vegetable-tanned calf strap, worn daily, typically lasts 2–4 years before replacement. Alligator, owing to stronger fibre structure, may last 3–6 years. Rubber Tropic straps have shorter lifespan (12–24 months) in humid climates but can exceed 4 years in dry conditions. Avoid prolonged water immersion, relative humidity above 80% (without ventilation), and very dry environments (below 30%) which accelerate brittle ageing of leather.
