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

The lug width is precisely 20 millimetres. This measurement represents the internal distance between the two lug horns that accommodate the strap. For the Divers Sixty-Five, this dimension ensures harmonious proportions on the 40mm case without lateral overhang. It is a standard specification among professional sports watches.

The choice depends on intended use and aesthetic preference. For discreet formality, an alligator strap with vegetable tanning or shell cordovan creates subtle elegance. For everyday versatility, vegetable-tanned calf offers the optimal balance between natural patina development and durability. If the watch is destined for water use, an FKM rubber solution provides absolute water resistance. A navy NATO strap references the design's original diving heritage.

The Oris Divers 65 uses standard spring bars. Use a specialized tool to gently compress the internal spring mechanism, allowing the bar to slide from the lug. Proceed carefully to avoid scratching the case. Milanostraps.it artisanal straps are pre-calibrated for 20mm lugs, ensuring installation without forcing.

Yes, completely. All straps in the 20mm collection have been tested on Oris models with identical lug dimensions. Compatibility is guaranteed for leather, NATO, and rubber straps alike. Our straps maintain the precise tolerances necessary for smooth insertion without lateral play.

A quality artisanal vegetable-tanned leather strap lasts 3 to 5 years with moderate daily wear. On a watch intended for diving, lifespan reduces to 18 to 24 months if frequently exposed to moisture and chlorine. We recommend alternating with a rubber solution for immersions, preserving the leather. The patina the leather develops is part of its appeal, but functionality remains the priority.
