Strap for Seamaster Planet Ocean 600M Co-Axial 45.5 Casino Royale

The lug width of the 2907.50.91 is 22mm. This measurement represents the internal distance between the horizontal pins that support the strap. It is important to measure correctly to avoid confusing the lug width with the width of the strap itself, which varies based on material thickness.

For this model we recommend alligator with supreme vegetable tanning, which combines the visual authority of the case with a natural grain that ages elegantly. Valid alternatives include vegetable-tanned calf for a more understated option, shell cordovan for extreme durability, or vulcanized butyl rubber if you frequent humid environments.

The strap is removed by gently pressing the end of the horizontal pin with an appropriate tool (spring bar tool) until it releases from the locking notch. Once the pin is extracted, you can slide out the used strap and insert a new one, aligning it perfectly before reinserting the pin. We recommend performing this operation on a soft surface to avoid scratching the case.

Yes, any strap made for a 22mm lug width is compatible with the 2907.50.91. However, verify that the pin is positioned correctly and that the strap does not show excessive lateral play once mounted. For optimal results, we recommend choosing straps made by experienced artisans who understand the visual proportions of such a massive case.

A leather strap with supreme vegetable tanning generally lasts 3 to 5 years with regular daily use. Durability depends on sun exposure, humidity, sweat, and frequency of wear. Alligator and shell cordovan offer greater longevity (5-7 years). Vulcanized rubber can last 4-6 years. Proper maintenance (regular cleaning and discreet conditioning) significantly extends the life of the strap.
