Frequently asked questions

What is the lug width of the Omega Seamaster Planet Ocean 232.98.44.22.01.004?

The lug width is 21mm, which is the distance between the two lugs of the case. This dimension is specific to this reference and is essential for selecting a compatible strap.

Which strap should I choose for the Seamaster Planet Ocean platinum 232.98.44.22.01.004?

For a platinum watch, dark brown alligator (conker, havana) is the classic choice. Alternatively, vegetable-tanned calf, Japanese shell cordovan for developing patina, or FKM rubber for intensive marine use.

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

Remove the used strap through the spring bar situated at the two lugs of the case. Insert the new strap in the same way, ensuring that the spring bar is properly secured and that the strap has a 21mm width section.

Can I use a quality aftermarket strap on this Omega?

Yes, provided the strap is built for 21mm lug width. Milano Straps artisanal straps guarantee full compatibility, premium materials and customization (initials, thread color, custom lengths).

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

A quality alligator or calf strap lasts 3-5 years with regular use, longer if properly maintained (protection from moisture, periodic conditioning). FKM rubber lasts 4-6 years. The patina that develops in the first months is normal and desirable in vegetable-tanned calf.
