Strap for Oris ProDiver 01 674 7630 7154

The Oris ProDiver 01 674 7630 7154 features a lug width of 28mm. This measurement is the original factory standard and corresponds to the distance between the case lugs. Always verify the measurement using a calliper positioned between the two attachment pins, excluding the case thickness itself.

For this chronograph diving instrument, the finest aesthetic and functional balance is achieved with an alligator strap finished with vegetable tanning, which develops a rich patina over time and complements the satin-finished titanium case beautifully. If intended primarily for underwater use, an FKM rubber strap offers superior resistance and resists degradation in saltwater environments. For daily versatility, medium-gauge calf leather represents the intermediate choice.

Remove the original strap using a spring bar tool, inserting the forked tip beneath the pin and lifting gently until it releases. Position the new strap by aligning one pin first, then the other, pressing with the tool until the pin fully seats in the case lugs. Protect the titanium case from scratches by applying protective tape around the lugs before beginning the operation.

Yes, all straps certified with a 28mm lug width are compatible with this model, regardless of manufacturer. However, verify that the strap thickness does not exceed 3.5mm in the contact zone with the case to prevent uneven pressure on the pins. Straps from specialised artisanal suppliers guarantee precise manufacturing tolerances and superior material quality.

A quality leather strap, finished with vegetable tanning and hand-crafted by artisans, can last 3-5 years with daily use and proper maintenance. Lifespan depends on frequency of wear, exposure to moisture and sunlight, and the inherent quality of the leather itself. Rubber or NATO straps offer superior durability (5-7 years), whilst a shell cordovan strap can exceed 10 years if properly treated with protective creams designed for leather conditioning.
