Strap for Divers Small Second - Date Great Barrier Reef / Rubber

The Oris Divers 01 643 7609 8585-Set RS features a lug width of 24mm, determined by the proportions between the 47mm case diameter and the primary attachment geometry. This measurement represents the linear distance between the two lug pins and must be respected precisely when purchasing a compatible strap. Recommended measurement method: use a digital calliper positioned horizontally between the pins, or consult a certified service centre.

The best strap selection depends on intended usage. For elegance and durability: Italian calfskin with vegetable tanning and natural grain texture. For daily versatility with minimal maintenance: NATO strap in cotton-nylon with satin-finished steel buckles. For occasional formal contexts: premium alligator with vegetable tanning, offering subtle luminosity. For water-based and diving activities: specialised rubber strap with deployante for sports attachments. The lug width to respect is always 24mm.

Strap replacement on the Divers Sixty-Five is performed by extracting the lug pins using a spring bar tool, a forked instrument with notched ends specific to horology. Position the notched end beneath the pin on the lower side, apply gentle upward pressure to compress the internal spring, extract the pin from the hole, and repeat on the other side. Insert the new strap (24mm lug width) and reinsert the pins until the closing click is felt. For those preferring to avoid risk of damage, entrust the operation to a specialised service centre.

Yes, the Oris Divers 01 643 7609 8585-Set RS is fully compatible with quality aftermarket straps, provided they respect the 24mm lug width. Milanostraps offers a dedicated collection of 24mm straps in leather, NATO, and rubber, crafted with leathers from private reserves and featuring millimetre-precise artisanal attachment. Compatibility is guaranteed by the standardisation of lug width: any 24mm strap will insert correctly via the original spring bar pins.

A high-quality leather strap (vegetable-tanned calfskin, alligator) mounted on the Divers Sixty-Five 47mm lasts approximately 3-5 years with moderate daily wear, conditional upon frequency of use, exposure to direct sunlight, and humidity levels. Vegetable-tanned leather ages naturally, developing patina and colour shifts that many consider a desirable characteristic. To extend lifespan: avoid saltwater swimming with leather strap, dry after sweat exposure, periodically apply conditioning products formulated for watch leather. A NATO or rubber strap offers extended durability, 5-8 years with equivalent wear, thanks to the inherent resistance of synthetic materials.
