FAQ
What is the lug width of the Eterna Adventure 1273.41.40.1718?
The lug width of the Eterna Adventure 1273.41.40.1718 is 20mm. This measurement is taken from the distance between the two springs that attach the strap to the case. It is essential to respect this specification to ensure compatibility between the watch and aftermarket straps, avoiding compromise solutions that could compromise both aesthetics and functionality.
Which strap is recommended for the Eterna Adventure 1273.41.40.1718?
For the 1273.41.40.1718, we recommend alligator or vegetable-tanned calf leather straps for elegant wear, or NATO or rubber straps for active use. The choice depends on context: premium leather emphasises the solid construction and ages with character, while rubber maintains functionality without aesthetic pretence.
How do I change the strap on the Eterna Adventure 1273.41.40.1718?
The strap is changed using a springbar tool (a tool for removing spiral springs). Position the watch with the lug facing you, insert the flat tip of the tool under the lateral spring, apply gentle pressure to make it snap, and slide the old strap out. Repeat on the other side. Install the new strap by aligning the holes with the springs and applying pressure until it clicks into place. If you are not experienced, consult a professional.
Which aftermarket straps are compatible with the 1273.41.40.1718?
All straps with a 20mm lug width are compatible with the Eterna Adventure 1273.41.40.1718. Compatibility is guaranteed by this geometric specification. Always verify that the seller specifically states '20mm' and that the strap does not present excessive thickness at the ends, which could interfere with the case.
How long does a leather strap last on the Eterna Adventure 1273.41.40.1718?
The lifespan of a leather strap depends on use and maintenance. A high-quality alligator or calf leather strap, with regular conditioning (every 6-12 months) and protection from extreme humidity, can last 5-10 years or more, developing a unique patina over time. Rubber has greater durability but patinas less characteristically. NATO fabric lasts 3-5 years before needing replacement.
