Frequently asked questions

What is the exact lug width of the Anonimo Epurato AM-4000.01.310.W42?

The Anonimo Epurato AM-4000.01.310.W42 has a lug width of 20mm. This measurement is taken from the centre of the left horizontal spring bar pin to the centre of the right one. Compatible straps must be exactly 20mm wide to ensure a fit without play and without structural tension on the case.

Which strap is most suitable for the Anonimo Epurato?

Alligator represents the most natural choice to enhance the minimalist design of the Epurato: its regular texture and absence of flaws amplify the geometry of the brushed steel case. For those who prefer evolution over time, vegetable-tanned calf offers a patina that dialogues magnificently with stainless steel. Shell cordovan is the arcane choice for those who understand the constructive complexities of leather.

How do I change the strap on my Anonimo Epurato AM-4000.01.310.W42?

To change the strap, you must remove the horizontal pins (spring bars) that hold the strap in the case. Use a dedicated spring bar tool to press the small return hook, extracting the pin. Once extracted, remove the old strap. Insert the new strap through the case lugs and reinsert the pins, verifying that they are fully locked.

Is an aftermarket strap from a different brand compatible with the Anonimo Epurato?

Yes, any strap with a 20mm lug width is compatible. The important thing is to verify that the width is exact and that the strap is constructed to equivalent quality standards. Avoid undersized straps or those with imprecise manufacturing tolerances, which would create lateral play on the case.

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

Durability depends on the material and usage. Quality alligator or calf provides 4-7 years of regular use before replacement is needed. Shell cordovan is the most durable material and can exceed 10 years with proper care. Critical factors are ambient humidity, sun exposure, cleaning frequency, and storage conditions when not worn.
