Frequently asked questions

What is the lug width of the Oris ProDiver 01 733 7646 7154-07 4 26 04TEB?

The lug width is 26 millimetres. This measurement is specific to larger wrists and ensures ergonomic weight distribution across the titanium case. To verify compatibility, measure the distance between the two horizontal pins at the case extremities.

Which strap is recommended for this ProDiver model?

For the ProDiver 01 733 7646 7154-07 4 26 04TEB, we recommend alligator leather straps with vegetable tanning for elegant transitions, or NATO and FKM rubber solutions for intensive diving use. Selection depends on usage environment: alligator favours formal and semi-professional contexts, whilst NATO and rubber guarantee absolute reliability underwater.

How do you change the strap on this watch?

Strap replacement is performed using a spring bar removal tool. Position the watch on a stable base, use the tool to compress the spring pin, remove the exhausted strap and insert the new one whilst aligning precisely. Verify that both pins are fully locked before wearing the watch.

Is an aftermarket strap compatible with the Oris ProDiver 01 733 7646 7154-07 4 26 04TEB?

Yes, any strap with a 26-millimetre lug width is compatible with the ProDiver. Milano Straps offers artisanal straps in various materials (leather, NATO, rubber) specifically engineered for this measurement. Always verify the strap features robust spring bars, essential for supporting the titanium case weight.

How long does a leather strap last on this watch?

A quality leather strap (alligator or calf with vegetable tanning) lasts 3-5 years with regular use, depending on saltwater exposure and maintenance. Salt water and perspiration accelerate ageing; periodic treatments with specific oils extend longevity. NATO and rubber straps have superior durability, lasting up to 7-10 years with minimal maintenance.
