Strap for KonTiki Date Grey / Strap

The lug width of the Eterna Adventure 1222.53.51.1362 is 20mm. This dimension is standard for medium to large sports watches and is critical when selecting a compatible strap. Always verify this measurement directly on the watch case by measuring the distance between the two lug attachments before ordering a new strap.

To enhance the bi-metallic case in stainless steel and rose gold, a strap in cognac or dark brown alligator is the optimal choice: the rose gold naturally complements the warm tones of aged leather. Alternatively, fine Italian or French calf leather offers aesthetic versatility, whilst a cotton/silk NATO strap adds sporting character. For more dynamic use, artisanal FKM rubber ensures durability and practicality.

Strap replacement requires specific tools: a spring bar tool (lug lever) and a stable work surface. Gently remove the elastic pins (spring bars) from the original lugs, slide out the old strap, then insert the new spring bars into the 20mm compatible strap and secure it to the case. For those unfamiliar with the process, consultation at Casati Milano (appointment-based artisanal atelier) is recommended to ensure no risk of damage.

Yes, milanostraps.it offers a selection of artisanal Italian-made straps specifically compatible with the 20mm lug width of the Eterna Adventure. Our straps utilise premium leathers (alligator, calf, shell cordovan) and hardware such as buckles and deployant clasps in stainless steel or precious metals. Each piece is crafted to measure to ensure precise compatibility with the original case attachments.

Durability depends on leather quality and usage patterns. An artisanal alligator or vegetable-tanned calf strap lasts 5–10 years of regular wear, developing a characteristic patina over time that increases aesthetic value. FKM rubber has comparable longevity (5–8 years) before showing signs of ageing. Regular maintenance (cleaning and conditioning leather) significantly extends strap lifespan.
