Strap for Seamaster Planet Ocean 600M Co-Axial 43.5 GMT Stainless Steel / Orange Numerals / Bracelet

The lug width of the Seamaster Planet Ocean 232.30.44.22.01.003 is 21 mm. This is the distance between the inner shoulders of the two metal lugs. You can verify it using a digital caliper positioned exactly between the two pins at 12 and 6 o'clock on the case.

For the 232.30.44.22.01.003, we recommend alligator straps with vegetable tanning for elegant daily wear, fine-grained calf leather for a minimalist style, or vulcanized rubber for those engaged in water activities. All must have a 21 mm lug width to ensure a precise fit without lateral play.

To change the strap, obtain a spring bar tool (a specialized tool) and insert it gently into the small hole on the outer side of the lug. Push the metal pin inward to free it from its seat, then remove the strap. Repeat on the other side, then insert the new strap by aligning the holes and reinserting the spring bars until they click into position.

Yes, any 21 mm lug width strap compatible with Omega can be used on the Seamaster Planet Ocean 232.30.44.22.01.003. However, to ensure the aesthetic integrity of the case and optimal water resistance, we recommend straps made by artisans who understand the robustness specifications required by a diving watch certified to 600 meters.

A natural leather strap (alligator, calf, cordovan) has an average lifespan of 3-5 years with daily use and regular care. The lifespan depends on sun exposure, salt water exposure, and maintenance frequency. Rubber or NATO straps last longer in aquatic environments, even up to 8-10 years if properly maintained.
