The new models from Omega are live on their website.
Besides Speedmaster 50th Aniversary they have following:
New Bullhead Chrono
New Ploprof 1200m
New PO Deep Black Ceramic in 39.5 mm
One of these PO is in Brown Ceramic and looks great.
There is no main page announcement.
You have to go thru the Seamaster page and scroll down
To be honest, I'm a little disappointed with the hike in price.
We still don't know if they managed to reduce the height of the watch.
