I went to the watch section of Central Festival Shopping Centre in Pattaya looking for a particular Omega model last week. They don't carry the brand and said Omega wasn't available in Pattaya. They referred me to Bangkok. The Pattaya store mentioned by Smiles appears to have closed down.

The shop is situated in Siam Paragon, not in the department store but just outside in the main mall across from the watch section.

My model was there but it is a lot more expensive than back home (taxes higher?) and no discount was offered. I've decided to buy it in Australia.
