The price range on Chrono24 and other watch platforms for the watch is between 18,000 Baht to 25,000 Baht. Tissot is selling it for 30,000 Baht (brand new). I bought the watch for around the same at 30,000 Baht (based on exchange rates then). I'm just looking for someone to value the watch rather than earn money from it, so 20,000 to 22,000 Baht would do (depending on cost of transaction - transportation, etc).
