Strap for KonTiki Chronograph Black / Bracelet

The lug width of the Eterna Adventure 1241.41.41.0217 is precisely 20mm. This measurement represents the internal distance between the case lugs and determines which strap width is compatible. To verify accurately, use a digital calliper positioned parallel to the case between the inner lugs.

The ideal strap depends on the intended use. For a classical approach, we recommend vegetable-tanned alligator in brown or cognac tones, which amplifies the brushed steel's materiality. For more sporty or humid environments, a fluoroelastomer rubber strap ensures durability and water resistance. Alternatively, Japanese shell cordovan offers superior material density and a patina that evolves over time with increasing richness.

Changing the strap requires a spring bar remover tool, a specific instrument that allows compression of the elastic pins securing the strap to the lugs. Position the remover between the lug and strap, apply gentle lateral pressure to create space, then extract the pin with tweezers. This procedure is reversible and requires no case disassembly. If uncertain, the Casati Milano atelier offers professional strap-change service with personalised consultation.

Yes, any strap with a 20mm lug width is constructively compatible with the 1241.41.41.0217. Milano Straps supplies artisanal 20mm straps crafted from premium materials (alligator, calf, shell cordovan, NATO, rubber) guaranteeing perfect mounting tolerances. Compatibility can be verified directly through the dedicated 20mm strap collection on the website.

The lifespan of a leather strap depends on tanning type and frequency of use. A well-maintained vegetable-tanned alligator typically lasts 5-7 years of daily wear, developing an increasingly rich patina. Japanese shell cordovan can exceed 10 years thanks to superior material density. Longevity extends significantly by reducing excessive moisture exposure and occasionally applying conditioning products specific to fine leather.
