Strap for KonTiki Date Black / Bracelet

The lug width of the Eterna Adventure 1222.41.41.0217 is 20mm. This measurement is determined by the distance between the attachment points on the case lugs. It is essential to verify this dimension before purchasing an aftermarket strap to ensure perfect compatibility.

The Eterna Adventure 1222.41.41.0217 pairs excellently with Italian alligator leather straps (for a more refined style), calf leather with a worked grain (for a sporty-elegant profile), NATO fabric (for tactical applications), or natural vulcanised rubber (for outdoor and humid conditions). Your choice depends on the primary use and the context in which you wear the timepiece.

The strap is changed using a specialised tool called a spring bar tool. Locate the pins that connect the strap to the case lugs; insert the spring bar tool's lever to compress the pin and slide out the strap. Once removed, insert the new strap by aligning the pins and ensuring the terminals are perfectly anchored. If you lack confidence, consult a professional watchmaker.

Yes, any strap with a 20mm lug width is compatible with this model. Milano Straps offers a wide range of artisanal 20mm straps, both in fine leather (alligator, calf) and technical materials (NATO, rubber). The key is always verifying that the lug width is precisely 20mm to avoid slippage or damage to the lugs.

The lifespan of a leather strap depends on usage, storage, and material quality. A high-quality alligator or calf strap, worn regularly but not daily in the same hole, can last 5-10 years. Exposure to sunlight, perspiration, and humidity accelerates ageing. Vegetable-tanned leather typically lasts slightly less than synthetically treated leather but develops a noble patina over time.
