The Classic 21010-0014 (aka: M21010-0014), seen from the bench

The Tudor Classic 21010-0014 features a 38mm stainless steel case with a screw-down crown, embodying Swiss watchmaking heritage. Powered by the ETA caliber 2824-2 movement, it offers hours, minutes, seconds, and date functions. The lug width measures 20mm, a historical Tudor standard compatible with most European artisanal and aftermarket straps. The proportioned case, soft lugs, and functional design reflect 1960s–1970s tool-watch principles without retro pastiche.

Frequently asked questions

What is the exact lug width of the Tudor Classic 21010-0014?

The lug width (ansa) of the Tudor Classic 21010-0014 is 20mm. This measurement is taken perpendicular to the two lateral lugs (pins) of the case. This specification is essential to ensure compatibility with aftermarket and artisanal watch straps.

Which type of strap is most suitable for the Tudor Classic 21010-0014?

For the Tudor Classic 21010-0014, we recommend alligator leather in dark brown or black, or English calf leather with vegetable tanning for a more casual aesthetic. The brushed stainless steel case pairs beautifully with straps featuring natural texture and artisanal finishes. Vulcanised rubber options are also available for sports-oriented wear.

How do you change the strap on a Tudor Classic 21010-0014?

Remove the strap using a spring bar tool: carefully insert the tool into the lateral hole of the lug, press downward to release the spring bar, then extract the old strap. To install the new strap, align the holes with the pins and apply uniform pressure until you hear a click of secure locking.

Are 20mm straps purchased online compatible with the Tudor Classic 21010-0014?

Yes, all straps with a 20mm lug width are compatible with the Tudor Classic 21010-0014. On milanostraps.it you will find artisanal straps ready to ship, customisable in length, initials and stitching thread. For a bespoke experience, the Casati Milano atelier creates artisanal straps with personal selection of hides and an 18-month warranty.

How long does a leather strap last on a Tudor Classic 21010-0014?

A high-quality leather strap with vegetable tanning has an average lifespan of 3–5 years with daily wear. Longevity depends on frequency of use, exposure to moisture and type of leather. Alligator and shell cordovan straps are more durable and can last 5–7 years. Regular maintenance (gentle cleaning and treatment with specialised creams) significantly extends service life.
