Frequently asked questions

What is the lug width of the Universal Geneve Okeanos 871.101/117D?

The lug width of the Universal Geneve Okeanos 871.101/117D is 20mm. This measurement indicates the distance between the lugs where the strap attaches to the case and is a critical specification for ensuring aftermarket strap compatibility. An incorrect measurement would result in unwanted lateral play and potential premature wear of the spring bars.

What is the best strap for the Okeanos 871.101/117D?

The choice depends on your intended use. For elegance, an alligator strap with vegetable tanning and a stainless steel deployant creates an exceptional material-aesthetic harmony. For daily practicality, a cordura NATO offers ease of changing and ergonomic comfort. For frequent water immersion, FKM rubber ensures durability without water absorption. A traditional calf leather with natural patina represents the ideal compromise between versatility and refinement.

How do I change the strap on my Universal Geneve Okeanos 871.101/117D?

Place the watch on a soft surface to avoid scratches. Using a spring bar tool, gently compress the elastic pin supporting the lug and slide the strap out from the lugs. Repeat on the other side. To install the new strap, align the hole in the leather with the elastic pin, press the tool to compress the pin, and slide the lug into the case lug. Release slowly to ensure proper seating and retention.

Can I use a quality aftermarket strap compatible with the 871.101/117D?

Yes, absolutely. Any strap with a 20mm lug width is compatible. The artisanal quality of a high-end aftermarket strap often surpasses the original integrated bracelet, allowing you to personalise your watch according to your aesthetic preferences. The key is to verify the lug width before purchase and choose manufacturers who guarantee precision in hole drilling and construction.

How long does a leather strap last on the Okeanos 871.101/117D?

A quality leather strap with proper vegetable tanning and artisanal finishing typically lasts 3–5 years with daily wear. Longevity depends on environmental factors (humidity, sun exposure, temperature fluctuations), frequency of use, and maintenance. Well-cared leather develops natural patina and improves tactilely over time. It is advisable to rotate multiple straps to distribute wear and allow the material to dry completely between uses.
