Frequently asked questions

What is the lug width of the Eterna Contemporary 7661.41.46.1324?

The lug width of the Eterna Contemporary 7661.41.46.1324 is 20mm. This dimension is specific to the model and must be strictly respected to ensure precise attachment to the case and avoid unwanted gaps or unnatural compression. We recommend verifying the width with a digital calliper, measuring the distance between the internal pins of the lug attachment.

Which strap is most suitable for the Eterna Contemporary 7661.41.46.1324?

The ideal strap for this model must respect the colour palette of the brushed and polished stainless steel case. Alligator with fine grain in dark brown, Japanese shell cordovan with natural patina, and vegetable-tanned calf leather in black represent the premium choices. For more sporty uses, grey-blue cotton NATO straps guarantee versatility without compromising solidity and aesthetic coherence.

How do you change the strap on the Eterna Contemporary 7661.41.46.1324?

Changing the strap requires a specific tool: the spring bar tool. Position the thin end of the tool inside the lug, gently pressing to compress the spring pin. Once loosened, remove the old strap. Insert the new 20mm strap by aligning the lug with the case holes and press the pin until it clicks into position. We recommend this operation on a clean surface and in natural light to avoid damage to the pins.

Can I use aftermarket straps compatible with the Eterna Contemporary 7661.41.46.1324?

Yes, aftermarket 20mm straps are fully compatible with the Contemporary 7661.41.46.1324, as long as they respect the same lug width. However, we recommend choosing straps made with noble materials (alligator, cordovan, calf leather) and finishes that dialogue with the stainless steel case. Avoid straps with overly saturated tones or artificial colours, which could alter the aesthetic balance of the timepiece.

How long does a leather strap last on the Eterna Contemporary 7661.41.46.1324?

The lifespan of a leather strap depends on intensity of use and material quality. A premium quality alligator or shell cordovan, worn daily, maintains structural integrity for 4-6 years. Vegetable-tanned calf leather lasts an average of 3-5 years. The natural patina that develops over time is desirable and adds character. We recommend rotating multiple straps to extend the life of each one.
