FAQ
What is the lug width of the Universal Geneve Okeanos 871.101/917A?
The lug width of the Universal Geneve Okeanos 871.101/917A is 20mm. This is the standard measurement between the two attachment pins of the case, essential for selecting compatible straps. You can verify this by measuring the distance between the horizontal terminals positioned at 12 and 6 o'clock on the case using a digital calliper.
What is the best strap for the Universal Geneve Okeanos 871.101/917A?
The best strap depends on your intended use: alligator leather with fine grain in dark brown tones offers sophistication and versatility; vegetable-tanned calf provides a refined-casual aesthetic with evolving patina; a grey NATO in cotton captures the sporty functional spirit; FKM rubber ensures superior water resistance and grip in wet environments. The ideal choice balances personal aesthetic preference with your usage context.
How do you change the strap on a Universal Geneve Okeanos 871.101/917A?
To change the strap: obtain a spring bar tool, secure the watch in a cloth holder, identify the pins at the lugs (12 and 6 o'clock positions), gently press downward with the tool to release the pin's end from its housing, extract the pin completely, remove the old strap, align the new strap with the lug holes, reinsert the pin ensuring both ends are securely seated. Avoid excessive force to prevent damage to the case attachments.
Which aftermarket straps are compatible with the Universal Geneve Okeanos 871.101/917A?

How long does a leather strap last on a Universal Geneve Okeanos 871.101/917A?
A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-5 years with moderate daily use, up to 7-10 years with regular maintenance (periodic cleaning, treatment with natural oils, complete drying after moisture exposure). Durability depends on frequency of use, exposure to water, perspiration and direct sunlight. FKM rubber is more durable but less refined; fabric NATO straps resist 5-8 years if not subjected to excessive mechanical stress.
