Strap for Divers Sixty-Five 40 Social Club Edition / Washington D.C.

The lug width is 20 millimetres. This measurement represents the distance between the two attachment points of the strap on the case lugs. Any strap measuring 20 millimetres will be perfectly compatible with this model. To verify compatibility, measure the horizontal space between the two lugs; if it corresponds to 20 millimetres, you have confirmed compatibility.

The choice depends on your intended use and aesthetic preferences. Vegetable-tanned leather in cognac or tobacco brown tones offers sporty elegance and pleasing contrast with the blue dial. A cotton ballistic NATO strap is ideal for field styling and versatility. Black FKM rubber is the technical solution for intensive marine use. Alligator represents a contained luxury compromise with distinctive granular texture. We recommend evaluating your actual use of the watch before making a decision.

The process is straightforward and requires only one tool: a spring bar removal tool. Position the tool in the slot beneath the lug and apply gentle pressure to release the spring pin, extracting it carefully downward. Repeat on the other side. The old strap is now free. To install the new strap, position the spring pin in the hole and press firmly until you hear a 'click' of engagement. Verify that the strap is securely attached before wearing the watch.

Yes, completely. Any strap measuring 20 millimetres in lug width is compatible with the reference 01 733 7707 4051 OSC-WDC-Set. Artisanal straps produced by milanostraps.it offer superior construction quality, aesthetic customisation, and material options (leather, NATO, rubber) that allow you to adapt the watch to different contexts. Compatibility is guaranteed by physical specifications; the quality of materials and craftsmanship remains a conscious choice of the owner.

Longevity depends on usage intensity, exposure to humidity, and leather quality. High-quality vegetable-tanned leather, used under normal conditions (not frequent immersion), maintains structural integrity for 5-8 years. Exposure to sunlight, salt water, and fresh water accelerates ageing. Leather subjected to regular maintenance (gentle cleaning, conditioning with natural oils) will significantly extend its lifespan. For the Divers 65, if you anticipate intensive marine use, FKM rubber offers greater durability. Quality artisanal straps can be reconditioned or repaired, further extending their longevity.
