The Seamaster Planet Ocean 222.62.46.50.01.001 (aka: 22262465001001), seen from the bench

The Seamaster Planet Ocean 222.62.46.50.01.001 is a 45.50mm red gold chronograph representing forty years of Omega's marine heritage. Powered by the Co-Axial caliber 3313 certified Master Chronometer, it features a blue ceramic dial, white gold applied indices, and unidirectional ceramic bezel with tachymeter scale. The case is solid red gold with 17.7mm thickness, water-resistant to 600 meters, and requires a 20mm lug width strap for proper proportions.

Frequently asked questions

What is the exact lug width of the Seamaster Planet Ocean 222.62.46.50.01.001?

The lug width is 20mm, ISO 1385 standard for large diameter cases. This measurement should be verified with a caliper positioned perpendicularly between the two Omega lugs, excluding the case curvature.

What strap do you recommend for a Seamaster Planet Ocean 45.50mm in red gold?

For red gold we recommend aged alligator, which naturally complements the warm chromatic character of the case, or dark shell cordovan for those seeking artisanal refinement with notable durability over time.

How do you change the strap on a Seamaster Planet Ocean with proprietary lugs?

The 222.62.46.50.01.001 features a proprietary bidirectional Omega lug system, incompatible with traditional spring bars. We always recommend service at an authorized Omega center or an expert watchmaker, as the system requires specialized tools.

What is the best aftermarket strap compatible with the Seamaster Planet Ocean 222.62.46.50.01.001?

Handcrafted 20mm straps custom-made for this model's lugs offer maximum compatibility. We advise against generic straps, as Omega's proprietary lugs require millimeter precision.

How long does a leather strap last on a sports watch like the Seamaster?

A well-crafted alligator or calf strap lasts 3-5 years with regular wear, thanks to greater skin density. Shell cordovan, due to its natural density, can exceed 7 years. Durability depends on environment (humidity, heat) and maintenance (periodic cleaning).
