Omega put rubber in the bezel of this watch.
Not lacquer, not enamel, not painted ceramic. The blue polished ceramic bezel has its 15-minute track injected with red rubber — a moulded rubber inlay set into fired ceramic, carrying the section of the scale a diver actually uses. Across every Omega we've written about, this is the only one where the material we sell is a structural part of the watch itself.
The rest follows the same two colours: a deep blue dial with rhodium-plated applied indexes and a minute scale in Omega's Liquidmetal, and a red-and-blue scheme taken from the Korean flag. Limited to 2,018 pieces, numbered, and made for a Winter Games that has since come and gone.
The size: 21mm
This takes a 21mm strap — not 20mm, and this is the size people get wrong on Planet Oceans.
The family rule, verified across our twelve Planet Ocean guides: 39.5mm takes 19mm, the older 42mm takes 20mm, 43.5mm takes 21mm and 45.5mm takes 22mm. This is a 43.5mm case, so it's 21mm. If you order 20mm because the box says Planet Ocean, it won't sit right.
Our Planet Ocean collection is cut in all four of those widths, so select 21mm on the product page and the strap will fill the lugs properly.
The box already contains the answer, and it's rubber
Here's what makes this reference different from every other Olympic Omega we've covered.
On all of them — the Aqua Terras, the Diver 300Ms, the Speedmaster — the watch ships on a steel bracelet and rubber is the thing you go and buy afterwards. Omega reversed that here. This Planet Ocean was presented on a blue rubber strap with red stitching, and the stainless steel bracelet was included in the box as the alternative.
So the question this page answers isn't whether rubber belongs on this watch. Omega settled that at the factory, and then reinforced it by moulding rubber into the bezel. The question is which rubber — and the factory offers exactly one combination, on a watch that was made in 2,018 examples and never restocked.
That's the gap. One colourway, no replacements, and a strap that takes the wear on a watch whose ceramic bezel and Liquidmetal scale will look identical in twenty years.
One practical note. The red inlay is the most distinctive thing on the watch and it sits on the bezel edge, where a slipped tool goes. Work on a soft cloth and keep the spring-bar tool square.
The best straps for the Planet Ocean PyeongChang 2018
1. Blue with red — the factory's own combination
We cut the exact relationship Omega chose. A blue strap with red reproduces the blue-body-with-red-detail pairing the watch left the boutique wearing, in the same material and at the correct width — which means you can wear the design as intended without putting further hours on a band you can't replace. For most owners this is the whole answer, and it's where I'd start.
2. Black with red — promote the red
The red on this watch isn't decoration; it fills the first fifteen minutes of a dive bezel, which is the part you set and watch. A black strap with red removes the competing blue from below the case and leaves red as the only colour in the assembly apart from the dial — so the functional zone becomes the thing your eye goes to, which is arguably what it was always for.
3. Navy blue — side with the ceramic
The tonal answer, and the most serious-looking. A navy blue rubber strap runs one continuous blue from lug to lug, matching the dial and the bezel body, which leaves the red inlay as the single interruption on an otherwise entirely blue watch. It's the version that reads as a dive tool rather than a commemorative, and the one that flatters the Liquidmetal scale most.
4. Full black — make both colours work
The neutral, and neutral earns its place on a two-colour watch. A full black rubber strap adds nothing, which means the blue reads deeper and the red reads brighter than either does against its own colour. It's also the most wearable of the four across a working week, and the one that makes a 43.5mm limited edition look like a watch rather than a souvenir.
The short version
21mm, not 20mm. Blue and red for the factory's own combination, black and red to promote the working part of the bezel, navy to go tonal, black to make both colours read.
Every strap in our Planet Ocean collection is cut for this case and carries a lifetime warranty on rubber — with free worldwide shipping and no import costs, part of why more than 50,000 customers have trusted us with their watches. Guides to every other Omega we've covered live in the Omega strap guide hub. Omega already decided this watch wears rubber. All that's left is choosing which.
