Frequently asked questions

What is the lug width of the Tudor Classic 21020-0002?

The Tudor Classic 21020-0002 features a lug width of 20 millimetres. This measurement must be taken from the inside of one lug to the inside of the opposite lug, where the strap connects to the case. Precise measurement is essential to ensure compatibility and safety in strap attachment.

What is the best strap for the Tudor Classic 21020-0002?

The optimal strap choice depends on intended usage. For formal contexts, we recommend natural alligator or vegetable-tanned leather in dark brown or black tones. For sports applications, FKM rubber or ballistic nylon ensure durability and practicality. Shell cordovan represents the ultimate choice for those seeking character and uniqueness that develops over time.

How do I change the strap on my Tudor Classic 21020-0002?

Strap replacement requires specific tools: a spring bar tool and precision positioning. Disconnect the original strap by gently extracting the lateral pins, then insert the new spring bars into the aftermarket strap and secure them to the case lugs. If you lack experience, we recommend consulting a professional watchmaker.

Can I use aftermarket compatible straps with the Tudor Classic 21020-0002?

Absolutely. Quality aftermarket straps constructed with 20mm lug width are fully compatible. Verify that the strap has been manufactured specifically for this width and that materials meet your quality standards. Straps from milanostraps.it are handcrafted and guaranteed for 18 months.

How long does a leather strap last on the Tudor Classic 21020-0002?

Durability varies based on material and frequency of use. A high-quality alligator strap typically lasts 3-5 years with proper care. Vegetable-tanned leather develops characteristic creases after 2-3 years, enhancing aesthetic appeal whilst remaining functional. FKM rubber demonstrates superior longevity (5-7 years). Protecting the strap from excessive moisture and direct sunlight significantly extends its lifespan.
