Strap for Divers Sixty-Five 40 Social Club Edition / Lisboa

The lug width is precisely 20mm. This measurement is specific to the model and corresponds to the historical proportions of 1960s dive watches. To verify compatibility, measure the internal distance between the lugs; it must be exactly 20mm to ensure proper strap accommodation.

The Divers 65 performs optimally with an alligator leather strap featuring vegetable tanning in black or navy blue tones. For aquatic environments or high-humidity conditions, a vulcanized rubber strap with a stainless steel deployante is the technically superior choice. A NATO strap in Cordura canvas offers a versatile alternative for daily wear.

The Divers 65 features fixed lugs soldered to the case. To replace the strap, you will require a spring bar tool to insert or extract the metal bars that secure the strap in position. Place the watch on a stable surface, apply gentle outward pressure to release the spring bar, then slide out the old strap and insert the new one.

Any strap with a 20mm lug width is compatible. milanostraps.it provides a dedicated collection of leather, NATO, and rubber straps specifically curated for 40mm watches with 20mm lug widths. We recommend selecting thicknesses between 3 and 4mm to maintain the formal proportions of the model.

A high-quality leather strap with vegetable tanning typically lasts 3-5 years with daily wear. The patina that develops is part of the natural ageing process. To maintain it, avoid prolonged immersion in salt water (though the Divers 65 is water-resistant), dry immediately after humidity exposure, and occasionally apply a lanolin-based leather balm to preserve suppleness.
