FAQ

What is the lug width of the Anonimo Epurato AM-4000.01.107.W66?

The Anonimo Epurato AM-4000.01.107.W66 features a lug width of precisely 20mm. This measurement is critical for aftermarket strap compatibility. To verify it, remove the original strap using a spring bar tool and measure the internal distance between the two lugs on the case. A strap of different width (19mm or 21mm) will not mount correctly.

What is the best strap for the Anonimo Epurato AM-4000.01.107.W66?

There is no universally "best" strap, but rather strategic choices based on aesthetic intent. Alligator in cognac or chocolate brown represents the most refined selection, emphasising the case's geometric order. Vegetable-tanned calf offers versatility and develops rich patina over time. For a utilitarian aesthetic honouring military heritage, canvas or nylon NATO maintains sobriety and character. Natural rubber suits contemporary, sportive interpretation. Your choice depends on aesthetic intention and context of wear.

How do I change the strap on the Anonimo Epurato AM-4000.01.107.W66?

Strap change requires a spring bar tool (or similar lever). Position the watch case upward. Use the spring bar tool to compress the elastic pin on one lug, creating space to withdraw the old strap. Repeat on the other side. Once removed, insert the new strap (20mm width) by aligning the holes with the elastic pins, compressing them slightly for secure fit. Verify proper alignment before wearing.

Can I use an aftermarket strap compatible with the Anonimo Epurato AM-4000.01.107.W66?

Yes, absolutely. The Anonimo Epurato AM-4000.01.107.W66 is fully compatible with 20mm aftermarket straps. Width certification is essential: a certified 20mm strap guarantees perfect fit without excess play. Milano Straps offers a dedicated collection of 20mm straps in various materials (alligator, calf, shell cordovan, NATO, rubber), customisable by colour and finish. Bespoke creation through the Casati Milano atelier enables exact-fit strap realisation.

How long does a leather strap last on the Anonimo Epurato AM-4000.01.107.W66?

Leather strap durability depends on material quality, tanning method, and usage conditions. An alligator or vegetable-tanned calf strap, with regular maintenance (gentle cleaning and annual conditioning), can last 5-8 years under moderate daily use. Exposure to water, perspiration, direct sunlight, and thermal fluctuation accelerates wear. Premium leather straps develop desirable patina over time, increasing aesthetic value. A NATO or rubber strap, by comparison, offers potentially longer lifespan (10+ years) due to reduced vulnerability to environmental factors.
