Frequently asked questions

What is the lug width of the Anonimo Epurato AM-4000.01.103.W22?

The lug width of the Anonimo Epurato AM-4000.01.103.W22 is 20mm. This measurement, expressed as the internal distance from pin to pin, determines compatibility with available straps in our catalogue. To correctly measure your watch's lug width, remove the current strap and measure the space between the two metal pins that hold the spring bars: this is the lug width. For the Epurato, this distance is fixed at 20mm, a consolidated standard for watches in this size category.

Which strap should I choose for the Anonimo Epurato AM-4000.01.103.W22?

Your strap choice depends on use context and personal aesthetic preferences. For daily urban wear, we recommend a full-grain calf leather strap or vegetable-tanned leather in natural cognac, which emphasises the watch's minimalism and develops a rich patina over time. For formal settings, alligator in dark grey or brown adds elegance without compromising the case's geometric purity. A NATO strap in sand or grey maintains the sporty, minimalist character, ideal if you alternate styles frequently. Natural rubber is the most durable and practical choice for wet environments or dynamic activities.

How do I change the strap on my Anonimo Epurato AM-4000.01.103.W22?

Changing the strap is a straightforward operation requiring no specialised tools. Position the watch on a soft surface to prevent scratches. Using a spring bar tool, gently lift the spring towards the top and outward from the pin: this will free one end of the strap. Repeat on the other side. Once the previous strap is removed, thread the new strap by inserting the pins through the case lugs until both spring bars re-engage in position. Verify the strap is securely fastened by gently pulling at all four corners.

Can I use an aftermarket strap on an Anonimo Epurato AM-4000.01.103.W22?

Yes, absolutely. The AM-4000.01.103.W22 is fully compatible with any aftermarket strap of 20mm lug width. Our handcrafted straps, made from premium materials such as Italian leather, alligator, vegetable-tanned leather and NATO, have been specifically designed for this width. Using aftermarket straps allows you to personalise your watch according to seasonal, stylistic and functional preferences, without any damage to the case or pins. Compatibility is guaranteed by the international standardisation of the 20mm lug width.

How long does a leather strap last on an Anonimo Epurato?

The lifespan of a leather strap depends on the material, tanning method and use context. A high-quality handcrafted full-grain calf strap, subject to moderate daily wear (worn 5-6 days per week), maintains structural integrity and aesthetic appearance for 3-5 years before requiring deep regeneration or replacement. Premium leathers such as shell cordovan can last 7-10 years under the same use pattern. Lifespan extends significantly if you rotate straps, using several in turn: this reduces humidity and mechanical stress on each individual strap. Regular maintenance – cleaning and conditioning every 3-4 months – substantially extends the strap's life.
