The Seamaster Planet Ocean 232.92.46.21.03.001 (aka: 23292462103001), seen from the bench

The Omega Seamaster Planet Ocean 232.92.46.21.03.001 is a contemporary evolution of the iconic diving lineage, featuring a 45.50mm Grade 5 titanium case certified to 600 metres depth. The deep blue dial reflects the ocean environment, paired with a unidirectional bezel, screw-down crown, and transparent sapphire caseback. Powered by the Omega 8500 calibre, an automatic movement with co-axial escapement and chronometer certification, it delivers precision of -4/+6 seconds per day and 60-hour power reserve. The 22mm lug width accommodates robust straps designed for demanding underwater use.

Frequently asked questions

What is the exact lug width of the Omega Seamaster Planet Ocean 232.92.46.21.03.001?

The lug width is 22mm. This width is determined by the 45.50mm titanium case and is fundamental for total strap compatibility. Verify by measuring the distance between the case lugs before ordering.

What is the best strap for the Omega Seamaster Planet Ocean 232.92.46.21.03.001?

It depends on use: for frequent diving, vegetable-tanned black calf ensures robustness against salt exposure; for elegant daily wear, navy blue alligator complements the dial; for maximum versatility, burgundy shell cordovan develops patina over time. Each choice is functional to your intended use.

How do I change the strap on my Seamaster Planet Ocean 232.92.46.21.03.001?

Obtain a spring bar tool or entrust it to a professional. The case lugs should be extracted by gently pressing from the opposite side; the new strap is inserted by aligning the lugs in the lateral slots. If unsure, contacting Casati Milano guarantees precision without risk of damage.

Can I use an aftermarket strap on this Omega?

Absolutely yes. The lug width must be exactly 22mm. Straps available online at milanostraps.it are specifically manufactured for this measurement and offer artisanal quality comparable to OEM straps, with the advantage of customization (initials, thread color, leather choice).

How long does a leather strap last on a dive watch like the Planet Ocean?

It depends on the material and use. Vegetable-tanned calf subjected to frequent diving or salt exposure lasts 2-3 years before leather degradation; alligator in non-marine daily use lasts 4-5 years. Chronic humidity reduces longevity. For frequent diving, we recommend alternating with technical rubber. Casati Milano offers 18-month warranty on all custom straps.
