Frequently asked questions

What is the exact lug width of the Eterna Contemporary 2570.41.60.1710?

The lug width of the 2570.41.60.1710 is 20mm. This dimension is critical for correct aftermarket strap installation and is measured between the internal contact points of the case where the spring bar mechanism sits.

Which strap material is most suitable for the Eterna Contemporary 2570.41.60.1710?

For the Contemporary 2570.41.60.1710, dark brown alligator or vegetable-tanned calf leather are the most appropriate choices. These materials echo the classic aesthetic of the model, emphasising its refined character. NATO straps represent an alternative for those desiring a more casual approach, whilst elastomers are ideal for versatile daily wear.

How do I correctly change the strap on the 2570.41.60.1710?

Strap replacement requires a dedicated spring bar tool. Locate the small hole in the case where the release mechanism sits, press gently and remove the lug. Insert the new strap and click the spring bar into position. If uncertain, consult a professional to avoid damaging the attachment mechanism.

Are aftermarket straps compatible with the Eterna Contemporary 2570.41.60.1710?

Yes, provided the lug width is precisely 20mm. Artisanal straps from Milano Straps are engineered specifically for this dimension and respect construction standards. Always verify that the strap is manufactured with precision, as even minor variations compromise correct installation.

How long does a leather strap last on a watch like the Eterna Contemporary 2570.41.60.1710?

A high-quality leather strap, with vegetable tanning or natural alligator, guarantees an average lifespan of 3-5 years with daily use, developing a patina that increases its character over time. Durability depends on maintenance, sun exposure and humidity. NATO straps and elastomers offer superior durability in high-wear environments.
