Strap for Style 28 Stainless Steel / Black-Diamond / Bracelet

The Tudor Style 12100-0004 features a lug width of 20 millimetres. This measurement indicates the distance between the two case lugs where the strap is inserted. It is crucial to verify this dimension before purchasing a replacement strap, as even slight variations (half a millimetre) would result in unwanted play or insertion impediment. Measure perpendicularly from one lug to the other using a ruler or digital calliper.

For the 12100-0004, we recommend high-quality leather straps with vegetable tanning, particularly alligator or premium calf leather. Black or dark brown alligator accentuates the elegant and minimalist character of the 28mm case, whilst vegetable-tanned calf offers greater versatility and suppleness. For less formal contexts or summer periods, dark grey or anthracite natural rubber, or a sober NATO fabric, complements the design without compromising the watch's formal spirit.

The Tudor Style 12100-0004 employs adjustable spring bars beneath the lugs. To remove the strap: position the watch on a soft surface (microfibre cloth), locate the spring bar inside the lug, use a specialist tool or fingernail to gently lift the bar's end towards the case centre, controlling pressure as you extract the strap. Repeat at the opposite lug. Installation follows the reverse procedure. Perform this operation with care to avoid scratching the stainless steel case.

Any strap certified with a 20mm lug width is compatible with the 12100-0004. Compatible straps range from premium artisanal segments (such as bespoke Casati Milano pieces) to standardised industrial brands. Online retailers offer a selection of 20mm-compatible straps ready for dispatch, customisable in leather, colour, initials, and stitching thread. Always verify the lug width dimension and thickness compatibility with your watch's spring bars.

A premium leather strap with vegetable tanning, worn in rotation (not daily) and maintained dry, typically lasts 3–5 years. If worn daily under stress (frequent moisture contact, perspiration, pressure), durability decreases to 18–24 months. Vegetable tanning permits periodic maintenance with leather-specific creams (not silicone), extending the strap's lifespan. Natural wear develops an esteemed patina. Replacing a strap is straightforward and economical owing to the standard 20mm lug width.
