Oris
Divers 01 649 7610 7164-Set— lug 20mm

The lug width of the Oris Divers 01 649 7610 7164-Set is precisely 20mm. This measurement is integrated directly into the titanium case structure and is critical for maintaining the original proportions. Always verify compatibility by measuring the attachment width with a digital calliper before purchasing an aftermarket strap.

For a diving chronograph of this calibre, we recommend aniline alligator or shell cordovan for formal wear, grained calf for versatility, and technical rubber or Cordura NATO for frequent immersions and marine environments. Your choice should reflect actual usage: leather for primarily land-based wear, water-resistant materials for saltwater exposure.

Strap replacement involves removing the spring bars using a dedicated removal tool, available at any watchmaking retailer. Lay the watch on a soft cloth, locate the small metal pins beneath the lugs, and insert the removal tool to compress the internal spring mechanism slightly. Once the first pin is loosened, proceed to the second. Ensure the replacement strap is sized for 20mm lugs and that the pins are installed securely.

Yes, provided the strap is specifically designed for 20mm lug width. Always verify exact dimensions from the manufacturer. Milano Straps maintains a complete range of 20mm straps in leather, NATO, and rubber, all tested for mechanical and aesthetic compatibility with Oris Divers-family watches.

A quality leather strap, under normal wear conditions, lasts between three and five years. Daily wear in humid or marine environments reduces longevity. Premium alligator or shell cordovan, properly maintained, will develop natural patina without premature degradation. Protect from prolonged sun exposure and rinse saltwater thoroughly. Rubber and NATO straps offer superior durability in extreme conditions, though they require more frequent replacement.
