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

The lug width measures 20mm, a standard specification that ensures compatibility with the vast majority of quality artisanal straps currently available. This width allows swift rotation between leather, rubber, or fabric NATO straps without requiring specialist tools.

For frequent diving use, FKM rubber or silicone is the optimal choice: it resists salt water and dries rapidly. For daily versatility, alligator leather with vegetable tanning offers elegance and durability, developing a noble patina over time. NATO fabric in high-density weave remains faithful to the model's historical heritage.

Use a spring bar tool (readily available online): position the tip beneath the lug spring, apply gentle pressure to compress the spring, extract the end from its seat, repeat from the opposite side. Once the old strap is free, insert the new one by aligning the lugs with the strap ends and verify correct spring positioning.

Absolutely. The 20mm lug width is standard and compatible with quality artisanal straps from specialist makers. We recommend verifying lug compatibility (thickness and groove depth) with your specific model, although in the vast majority of cases, purpose-made 20mm straps ensure universal fit.

A quality alligator leather with vegetable tanning lasts approximately 5-8 years of daily wear, whilst developing a fascinating patina that enhances the overall aesthetic. Longevity increases if the watch is worn in rotation with other models. Rubber, conversely, tends to degrade after 3-4 years when exposed to intense UV radiation.
