Strap for Classic 38 Stainless Steel / Yellow Gold / Diamond / Silver / Bracelet

The Tudor Classic 21023-0005 features a lug width of 20 millimetres. This measurement should be verified by positioning a calliper perpendicular to the inner shoulders of the case lugs. It is essential to select a strap of precisely 20mm to preserve the aesthetic proportions of the model and ensure a fit without gaps or visual excess.

This depends on intended use and personal preference. For formal contexts, high-grade alligator with pronounced grain is the ideal choice, as it dialogues naturally with the dress character of the model. For daily versatility, vegetable-tanned calf leather in brown or black shades offers elegance without rigidity. Shell cordovan represents the most exclusive option, thanks to the density of the fibres and natural lustre. For casual environments, cordura NATO in beige or navy blue renders the 21023-0005 an informal companion without compromise on legibility.

Changing the strap on a Tudor requires a specific tool: a spring bar remover (a small metal extraction device). Position the watch horizontally, insert the tip of the remover under the connecting bar spring, and apply gentle pressure to release the bar from one side. Once released, the strap removes easily. The new strap is fitted by reversing the operation. To prevent scratches, protect the case with a soft cloth during the process.

Yes, any quality strap with a 20mm lug width is compatible with the 21023-0005. Compatibility is guaranteed by the lug width and the geometry of the case horns. However, to achieve maximum results from the model, it is advisable to select noble materials (alligator, calf, shell cordovan) and finishes coherent with the dress-casual style. An artisanally crafted strap, with hand-stitched seams and refined finishes, further enhances the proportions of the case.

The lifespan of a leather strap depends on frequency of use, environmental conditions, and leather quality. High-quality calf leather subjected to daily use typically lasts between 3 and 5 years. Alligator, thanks to the density of its fibres, can last up to 7–10 years. To extend the strap's lifespan, avoid prolonged exposure to moisture and direct sunlight, and subject it to periodic cleaning with leather-specific products. An artisanal strap with hand-stitching can be regenerated through replacement of the inner sole, further extending its useful life.
