When I walked in, he was not around and I took quite a liking to an Omega model. So i enquired for the best price from the salesgirl (who is completely ignorant - she thought the planet ocean was called seamaster professional.) Nevertheless, she called the manager on her hp and asked him to get into the shop as a prospective customer is interested.
a planet ocean IS a seamaster professional.
Well, the naming of the Seamaster range is always a big confusion, as the model name doesn't show on the dial of the watch but only at the case back, and its a norm for everyone to look at the dial when they first encounter the watch, and they will read it as Seamaster or Seamaster Professional (normally divers design will carry the "Professional" wording, including both Planet Ocean and Diver 300m models, while non-diver model like Aquaterra will carry only Seamaster, but having said that, there are exceptionals, let's not drill too deep into it.)
Seamaster range is basically composed of 3 main models i.e. Planet Ocean, Aquaterra and Diver 300m, of course there are some rare minorities like the Bull head, Ploprof.. They are all quite distinctive in the design for a different requirement and market.
So lets use the correct model names in the future!
