What I'm asked about the Omega Seamaster Planet Ocean 232.30.46.51.01.001
What strap size does the Omega Seamaster Planet Ocean 232.30.46.51.01.001 take?
The Omega Seamaster Planet Ocean 232.30.46.51.01.001 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Omega Seamaster Planet Ocean 232.30.46.51.01.001 be changed?
Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.
Can I put a leather strap on the Omega Seamaster Planet Ocean 232.30.46.51.01.001?
Yes, in 20 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber. On a 46 mm diver I go for a full-thickness strap, not a thin one.
Which strap do you recommend for the Omega Seamaster Planet Ocean 232.30.46.51.01.001?
Rubber if you wear it in the water; otherwise a 20 mm calf strap, full thickness. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
Are aftermarket straps compatible with the Omega Seamaster 232.30.46.51.01.001?
Yes, provided they respect the 20mm lug width. Milano Straps offers certified straps for this size, crafted in artisanal leather (alligator, calf, shell cordovan) and technical rubber. All our 20mm straps are pre-cut according to Seamaster Planet Ocean specifications and come with spare pins.
How long does a leather strap last on a Seamaster Planet Ocean?
A quality artisanal leather strap, if subjected to reasonable use (worn 3-5 days weekly), typically lasts 3-5 years before requiring replacement. Vegetable-tanned alligator and shell cordovan age better, developing patina and maintaining structure. Frequent exposure to water, sweat, and UV rays shortens lifespan. Milano Straps offers an 18-month warranty on all custom straps.
