Strap for KonTiki Date Silver / Strap

The lug width of the Eterna Adventure 1222.41.11.1302 is 20mm. This dimension is measured internally between the two spring bar pins that protrude from the case lugs. Always verify this measurement before ordering an aftermarket strap to ensure perfect compatibility without lateral play.

The ideal strap depends on your intended use. For versatile elegance, we recommend alligator or shell cordovan in neutral tones (brown, cognac, burgundy). For pure sportiness, a cotton or synthetic NATO offers practicality and quick adjustment. A FKM rubber solution is ideal for aquatic or salt environments. Your choice should reflect your wrist's daily vocation.

Strap replacement requires gentle handling: position the watch with the case facing upward and, using a blunt-tipped tool (spring bar tool), insert it under the lug pin, exerting slight pressure to lower the internal retaining mechanism. Withdraw the pin from its seat and repeat on the opposite lug. Install the new strap by aligning the pins in their seats and ensuring the retainer clicks fully into place.

Yes, provided it is specifically manufactured for 20mm lugs. Dimensional compatibility is guaranteed when the strap presents attachment points calibrated precisely to this width. We recommend always verifying technical specifications with the manufacturer. Bespoke straps, such as those from the Casati Milano atelier, offer manufacturing tolerances that ensure impeccable fit without play.

A leather strap's lifespan depends on material and usage. High-quality alligator with vegetable tanning resists approximately 3-5 years of daily wear, developing a patina that increases its character. Shell cordovan, being more robust, can exceed 7-8 years. Longevity extends significantly if the strap is stored away from direct light and heat sources during periods of non-use, and if it undergoes regular maintenance (gentle cleaning and occasional conditioning).
