Strap for KonTiki Date Full Black

The lug width of the Eterna Adventure 1222.43.41.1302 is 20mm. This measurement represents the distance between the two spring bar attachment points and corresponds to the width of the case at the lug level. It is the correct specification for purchasing compatible replacement straps.

Selection depends on intended use: for formal contexts, alligator or vegetable-tanned calf leather; for daily/sports wear, a technical NATO strap offers superior grip and moisture resistance; for intensive hiking, vulcanised rubber ensures absolute reliability. The Adventure maintains its character with all these solutions thanks to its constructive aesthetic.

Strap replacement is straightforward: use a spring bar tool to depress the small metal pin located beneath the lug. The pin ejects laterally from its seat. Repeat on the opposite side, remove the old strap, insert the new one by aligning the pin, and allow it to click back into place. This is a reversible operation requiring no specialised tools.

Yes, absolutely. Any strap with a 20mm lug width is mechanically compatible with the Eterna Adventure 1222.43.41.1302. We recommend vegetable-tanned leather or NATO textile straps to maintain the tool watch aesthetic, avoiding visually discordant solutions such as mesh bracelets or excessively thick rubber straps.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years of moderate daily wear. Lifespan extends to 7-10 years if worn sporadically or under protective conditions (not exposed to intense humidity). The natural ageing of leather is desirable: the patina that forms narrates the watch's history. NATO straps last longer (10+ years) but wear in the crease zones.
