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

The lug width of the Tudor Style 12100-0014 is 20mm. This means that the strap must have a width of 20 millimetres at the spring bar seat where it connects to the watch lugs. It is important to verify this measurement before purchasing an aftermarket strap, as undersized (18mm) or oversized (22mm) formats will not ensure a proper fit and mechanical security.

The choice depends on usage and aesthetic preferences. For formal wear, we recommend alligator in dark brown or black, which emphasises the squared proportions of the case and pairs perfectly with the brushed steel. A textured calf leather in black or burgundy offers versatility and develops a natural patina over time. For sports or summer use, a grey anthracite NATO or fluoroelastomeric rubber strap keeps the wrist cool and preserves the white dial without visual heaviness.

To change the strap, position the watch on a flat surface with the lugs facing upwards. Locate the spring bar pin on each lug (a small metal bar that passes through the lug seat). Using a spring bar tool, press the pin downwards from the rear to release the old strap. Once the pin gives way, remove the old strap. Insert the new 20mm strap into the seat and, using the same tool, press the pin back into place. Verify that the pin is securely fixed before wearing the watch.

Yes, you can use any aftermarket strap with a 20mm lug width. Aftermarket straps allow aesthetic customisation without mechanical compromise, provided they respect the correct lug width. On milanostraps.it you will find a selection of 20mm straps compatible with the Tudor Style 12100-0014, customisable in material, colour and finishes. To ensure mechanical and aesthetic compatibility, always verify the case dimensions (28mm diameter) and lug width (20mm).

A natural leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with moderate daily use and proper maintenance. Durability depends on factors such as the type of tanning, exposure to moisture, body perspiration and frequency of use. Vegetable tanning resists natural ageing better than industrial tanning, developing a more pleasing patina. To extend strap life, avoid prolonged moisture, dry it after rain, and replace it during winter months with rubber or fabric alternatives. Casati Milano offers an 18-month warranty on artisanal bespoke straps.
