Strap for Classic 28 Stainless Steel / Yellow Gold / Diamond / Silver-Diamond / Bracelet

The lug width of the Tudor Classic 22023-0004 is 20 millimetres. This is the internal distance between the two case attachments and is the critical measurement for selecting any compatible strap. The spring bars (the steles that attach the strap to the lugs) must have a 20-millimetre diameter to fit correctly.

For the Tudor Classic 22023-0004, noble leather straps of high quality are recommended: alligator with regular grain amplifies the elegance of the two-tone gold and steel case; shell cordovan offers initial rigidity that evolves into natural softness; calf leather with vegetable tanning guarantees accelerated patina and sophisticated aesthetics. Alternatively, a cotton-nylon NATO strap is suitable for summer use, preserving the compact proportions of the case.

To change the strap, extract the spring bars from the case using a dedicated spring bar removal tool. Position the tool beneath the bar and push gently upward until the internal spring is released; repeat on the other side of the case. Insert the new strap by aligning the holes with the bars, ensuring the strap has a 20-millimetre lug width, and reposition the bars at the ends. If you lack technical expertise, entrust the operation to a qualified watchmaker.

The lifespan of a leather strap depends on construction quality, material and use. High-quality alligator can last 5–8 years with daily wear and ordinary maintenance (occasional cleaning, protection from stagnant water); shell cordovan resists 6–10 years owing to material density; calf leather with vegetable tanning has durability comparable to cordovan but develops more evident patina. The buckle, if made of resistant metal or a deployante, guarantees longevity on par with the strap. On request, Casati Milano offers renewal services and replacement of worn components.
