Frequently asked questions

What is the lug width of the Eterna Contemporary 2940.56.41.1357?

The Contemporary 2940.56.41.1357 features a 20-millimetre lug width. This measurement is taken from the outer edge of the right lug pin to the outer edge of the left lug pin, perpendicular to the case. It is the specific construction specification determined by the case width of the Eterna.

What is the best strap material for the Eterna Contemporary?

For the Contemporary 2940.56.41.1357, we recommend alligator leather with vegetable tanning or calf leather, both capable of ageing with dignity alongside the case's stainless steel. Alligator features a distinctive scale texture and a patina that enriches over time. Calf leather ensures compact structure and uniform grain. NATO and rubber are valid alternatives for those prioritising everyday practicality.

How do you change the strap on an Eterna watch?

Changing the strap on an Eterna Contemporary requires a specific tool to extract the lug pins: an instrument with two conical tips. Position the watch on a soft surface, locate the transverse pin beneath the case, insert the tip into the space between the pin and the case, gently push to extract the pin. Repeat on the other side. Align the new strap with the holes and reintroduce the pins, ensuring they are secure. Avoid forcing to prevent damage to the case lugs.

Can I use aftermarket compatible straps on this model?

Yes, all artisanal straps with a 20-millimetre lug width are compatible with the Contemporary 2940.56.41.1357. Verification of the measurement prior to purchase is essential. Straps crafted from quality artisanal leather, NATO fabric or technical rubber pair effectively with this stainless steel case, offering aesthetic choice without compromising functionality.

How long does a leather strap last on a ladies' watch?

A quality leather strap, correctly maintained, typically lasts between three and seven years. On a ladies' timepiece such as the Contemporary, which experiences moderate wear compared to men's wrist models, longevity tends toward the upper end of the range. Ageing accelerates with frequent exposure to moisture and perspiration. Periodic maintenance with specialist products, combined with strap replacement when necessary, preserves the appearance of your Eterna.
