Strap for Okeanos Stainless Steel / Silver / Bracelet

The lug width of the Universal Genève Okeanos 871.101/117M is 20 millimetres. This measurement represents the usable space between the two lugs where the strap is attached. For precise verification, use a digital calliper to measure the distance between the lugs, or consult a professional watchmaker.

For the 871.101/117M, strap selection should depend on intended use: alligator or vegetable-tanned calf leather for formal and daily wear; NATO or Zulu straps in nylon or polyester for sports and water activities; FKM rubber (Viton) for frequent diving and aggressive marine environments. Colour choice should complement the dial for optimal aesthetic harmony.

To change the strap, remove the spring bars connecting the strap to the case lugs. Use a spring bar tool to press the elastic mechanism and slide the bar out. Repeat for both lugs. Insert the new spring bars into the compatible 20mm strap and attach to the case. If uncertain, consult a professional watchmaker to avoid damage.

Yes, all straps with a 20mm lug width are compatible with the Universal Genève Okeanos 871.101/117M, provided they are manufactured by reputable suppliers respecting precise tolerances. Always verify the strap is exactly 20mm between attachment points to ensure correct fit and prevent abnormal stress on the case.

A quality leather strap with vegetable tanning typically lasts 3–5 years with moderate daily use, as moisture, perspiration and UV exposure accelerate deterioration. Shell cordovan and alligator straps last longer (5–8 years) due to superior material density. Regular maintenance (cleaning and conditioning) significantly extends useful life. For frequent diving, rubber is the most durable solution (10+ years).
