Strap for Divers Small Second - Date Carlos Coste

The lug width of the Oris Divers 01 643 7584 7154-Set is 24 millimetres. This specification is tailored to the Divers collection and calculated to balance the proportions of the 47-millimetre case diameter. Measure the distance between the two lateral lugs to verify compatibility with any aftermarket strap.

For the titanium 47-millimetre model, we recommend alligator or calf leather with vegetable tanning in brown or black tones to balance visually against the grey-titanium case. If frequent water immersion is intended or daily wearability is a priority, a NATO fabric or FKM rubber strap ensures practicality without aesthetic compromise.

Use a spring bar tool (a small lever) to gently remove the elastic pins from the lugs. Insert the flat tip of the tool into the groove on the sides of the pin, applying light perpendicular pressure until the internal spring disengages. Once the pin is extracted, the strap lifts away. To install a new strap, align the lateral holes and reinsert the pin, confirming the mechanical engagement.

Yes, any strap with a 24-millimetre lug width is mechanically compatible. Verify that the pin diameter matches the standard (1.8 mm) and that the aesthetic of the new strap harmonises with your Divers' character. Artisan straps featuring an integrated deployante clasp require additional verification of total length to avoid excessive tension on the case.

The longevity of a leather strap depends on frequency of water immersion and tanning quality. A vegetable-tanned calf strap, subjected to regular diving, maintains structural integrity for 18–24 months before showing significant degradation. High-quality shell cordovan can extend this cycle to 30–36 months. Maintenance—rapid post-immersion drying and occasional protective wax treatment—substantially increases durability.
