If that is the case, sorry for any bad information.
On the other hand, there is still the official Omega website which clearly shows an Omega/King Power store still open in Pattaya: https://www.omegawatches.com/stores/...ore%5D=bangkok . Perhaps they are behind the times
The Emporium and Paragon stores I believe are still open. If you can afford an Omega watch, why not just rent a helicopter which will drop you on top of Paragon.
