Strap for Classic 38 Stainless Steel / Yellow Gold / Diamond / White-Diamond / Bracelet

The Tudor Classic 21023-0002 features a lug width of 20 millimetres. This measurement is critical when selecting an aftermarket strap that is compatible with your watch. To verify compatibility, measure the distance between the two lugs at the top and bottom of the case: it should correspond exactly to 20mm.

For a bicolour Tudor Classic 21023-0002 in stainless steel and yellow gold, an alligator leather strap represents the most refined choice: the natural texture of the leather harmonises perfectly with the watch's formal aesthetic. A dark brown or cognac alligator amplifies elegance, whilst lighter shades emphasise a summer aesthetic. Alternatively, vegetable-tanned calf leather offers versatility and ages beautifully over time, developing a natural patina.

To change the strap on your 21023-0002, you will need a spring bar tool. Position your watch securely, use the tool to compress the spring bar gently and extract it from its seat. Once the old strap is removed, align the new strap and reposition the spring bar until it is fully seated. If you prefer to avoid DIY work, professional ateliers such as Casati Milano perform this service with guaranteed precision.

Any strap with a 20mm lug width is compatible with the 21023-0002. At milanostraps.it you will find a comprehensive collection of 20mm straps in various materials: alligator, calf, shell cordovan, NATO, canvas, rubber and other finishes. Each strap is tested to ensure constructive and aesthetic compatibility with your Tudor Classic.

The lifespan of a leather strap varies according to the material, frequency of wear and environmental conditions. A quality alligator or calf strap, worn daily, typically lasts 2–4 years before requiring replacement. Vegetable-tanned leather, due to its natural resilience, tends to last longer than industrial leathers. Exposure to sunlight, heat and humidity accelerates ageing. Casati Milano's atelier provides an 18-month warranty on bespoke straps, ensuring lasting construction quality.
