Just saw this, reference 215.32.43.21.04.001. No formal announcements or reviews by any watch publication. Not on the Omega site. Apparently, an America's Cup edition limited to 2021 pieces. Looks like the 2018 Pyeongchang Olympics LE, but with white instead of blue dial and different bezel markings. What I find weird is that it's 43.5mm, but the case size on the reference number is usually rounded up to 44.. so not sure if the reference number is correct or if they're rounding up the .5mm now.
Omega has been rounding up in the ref # for a while. The inscription at the bottom is for the 36th America's Cup – which is Sat, Mar 6, 2021 – Sun, Mar 21, 2021 – so I'm guessing this is a leak of an upcoming PO model.
Oh, weird. I missed that in your original post. If you swap the 43 out for 44 in your ref #, you get an existing model: https://www.omegawatches.com/en-us/...ial-master-chronometer-43-5-mm-21532442104001 I wonder if the ref # is correct? Being what I think is a leak, I would put some doubt on the ref # being solid.
This model does show up on WatchBase. It is a limited edition of 2021. https://watchbase.com/omega/seamaster-planet-ocean/215-32-43-21-04-001
