The Divers 01 643 7637 7454-07 4 24 34TEB, seen from the bench

The Oris Divers Titan C Small Second – Date 44 is a contemporary evolution of underwater watchmaking heritage from the 1960s. It features a 44mm titanium case with black ceramic bezel and black rubber strap, powered by the Oris 643 caliber movement with hours, minutes, small seconds, and date. The titanium construction reduces weight while maintaining structural rigidity, and the ceramic bezel resists scratches better than traditional aluminum. The 24mm lug width is precisely dimensioned to ensure proper strap fit without lateral protrusion.

Frequently asked questions

What is the lug width of the Oris Divers 01 643 7637 7454-07 4 24 34TEB?

The lug width is 24.00mm. This width is specific to the Divers 65 model with 44mm case and was engineered by Oris to ensure harmonious proportions between lugs without lateral overhang. Always measure the lug width by positioning a ruler perpendicular to the internal lugs of the case.

Which strap would you recommend for the Oris Divers 01 643 7637 7454-07 4 24 34TEB?

We recommend vegetable-tanned alligator leather (which develops a rich patina over time) or Tuscan calf leather for understated elegance. For a more technical aesthetic, a NATO strap in grey or dark blue cordura maintains the tool watch identity. For aquatic use, FKM vulcanised rubber is chemically resistant and practical. Milano Straps personalises every strap to 24mm lug width specifications.

How do I change the strap on the Oris Divers?

Remove the original strap using a spring bar tool (a small mechanical device). Position the tool in the gap between lug and case, gently flex the internal metal pin and slide the strap away. Install the new strap by reversing the procedure: align the lug holes with the pins, press the spring bar until it clicks into place. No watchmaker is required—anyone capable of following precise instructions can accomplish this easily.

Is the Oris Divers 01 643 7637 7454-07 4 24 34TEB compatible with aftermarket 24mm straps?

Yes, it is fully compatible. Any strap with 24mm lug width will fit the Divers lugs. Milano Straps manufactures artisanal straps specifically customised for this measurement, guaranteeing precise tolerances and finishes that match your watch's quality standards.

How long does a leather strap last on the Divers?

A quality leather strap, such as those vegetable-tanned by Milano Straps, lasts 3-4 years with moderate wear (5-6 days per week). Longevity depends on humidity, sun exposure and maintenance: condition regularly with natural balms, avoid prolonged fresh water immersion and store in a dry environment. The patina that forms is desirable and enhances the overall aesthetic value.
