Strap for Divers Sixty-Five 40 Social Club Edition / Tel Aviv

The lug width is 20 millimetres. This measurement is critical for ensuring proper and stable strap installation. To verify, use a digital calliper positioned between the spring bar pins on either side of the case.

For this model, fluoroelastomer rubber straps are recommended for intensive diving, leather with vegetable tanning for natural ageing, or nylon NATO straps for versatility and quick replacement. Selection depends on primary use: technical diving, casual-formal wear, or diving emergency protocols.

Position the watch horizontally on a soft surface. Locate the spring bar pins on both sides of the case. Using a flat, non-abrasive tool (butter knife tip), gently push the pin towards the case centre until it disengages, allowing the strap to slide away. Repeat on the opposite side. For installation, align the new strap holes with the pins and push gently until the locking click is felt.

Yes, any strap with a 20mm lug width is mechanically compatible. However, verify that the pin holes are correctly aligned and that thickness does not exceed 5mm to avoid case compression. Quality-certified straps (vulcanised leather, NATO Mil-Spec, FKM rubber) guarantee structural reliability in all conditions.

A quality leather strap with vegetable tanning and artisanal stitching typically lasts 3–5 years with moderate daily wear. In saline environments or with frequent diving, durability decreases to 18–24 months. Regular maintenance (drying after water exposure, natural wax treatment every six months) significantly extends lifespan. Rubber or NATO straps, being waterproof, exceed 7–10 years of durability.
