Frequently asked questions

What is the lug width of the Anonimo Epurato AM-4000.01.101.W11?

The lug width of the Anonimo Epurato AM-4000.01.101.W11 is 20 millimetres. This measurement represents the inner distance between the integrated lugs on the case. Every compatible strap must have precisely 20 millimetres width to fit correctly into the original attachment points without play or forcing.

Which strap is most suitable for the Anonimo Epurato?

Given the minimalist aesthetic and geometric construction of the Epurato, a vegetable-tanned leather strap represents the most harmonious choice. A rich cognac or dark brown Italian calf leather emphasises the solidity of the stainless steel case. For sportier profiles, a heavyweight cotton NATO or technical FKM rubber strap offers practical versatility without compromising visual coherence.

How do you change the strap on the AM-4000.01.101.W11?

The strap is replaced by removing the spring bars that connect the strap terminals to the case lugs. Use a dedicated tool, such as a spring bar remover, to compress the internal spring and extract the pin. Once the lugs are freed, align the new strap correctly and reposition the bars, ensuring they click securely into place. If unfamiliar with the procedure, seek assistance from a specialist.

Which aftermarket straps are compatible with the AM-4000.01.101.W11?

All straps manufactured with a 20-millimetre lug width are compatible. Milano Straps offers a curated selection of quality leather straps, NATO options, and technical rubber, all precisely dimensioned for 20mm. Each product is tested to ensure accurate compatibility with the integrated case attachments.

How long does a leather strap last on this watch with daily wear?

A high-quality vegetable-tanned leather strap typically endures between 18 and 36 months of continuous daily use, varying according to ambient humidity, wear frequency and care applied. Leather deteriorates naturally; wear concentrates on the inner keeper, subject to greater tension and flexing. By applying protective wax periodically and rotating between multiple straps, you significantly extend operational lifespan.
