Strap for Okeanos Stainless Steel / Grey

The lug width of the Universal Geneve Okeanos 871.101/017D is 20mm. This dimension corresponds to the external distance between the case lugs at the attachment point. Respecting this measurement is essential to ensure correct insertion and structural stability of the strap on the case.

For the 871.101/017D model, we recommend alligator leather with vegetable tanning in dark brown or chrome-tanned calf that creates elegant contrast with the blue dial and steel case. For sports environments, a polyamide NATO or FKM rubber strap ensures maximum versatility. Shell cordovan represents the premium choice for exceptional durability.

The strap is changed using a spring bar removal tool. Position the watch on a stable surface, insert the bifurcated end of the tool into the lateral slot of the lower lug, apply gentle pressure to compress the internal spring, then extract the pin. Repeat on the upper lug. Insert the new strap by aligning the holes with the pins and push until the spring is fully seated.

Yes, any strap with a 20mm lug width is compatible, provided that the thickness in the transition zone does not exceed 4.5mm. This limitation is due to the integrated case geometry of the Okeanos. We recommend verifying the strap specifications before purchase.

An alligator or vegetable-tanned calf strap lasts approximately 3-4 years with regular use. Shell cordovan reaches 6-8 years. Durability depends on sun exposure, humidity, and frequency of use. A polyamide NATO strap is virtually unlimited. An FKM rubber strap maintains elasticity for 5-7 years.
