Living in Rayong and have 2 watches that need repair. Does anyone know where I can find a watch maker in Rayong or somewhere else in the Eastern Seaboard?

Not in Rayong itself, but at the large Tesco in Banchang there is a guy that repairs watches. He has done good work for me on a couple of old Seiko chrono watches before. If your timepieces are very valuable, I would recommend you contact the manufacturer though.

Thanks, I’ll check it out. An average watch maker should be sufficient, need to exchange crowns on 2 watches and replace a 3 hand quartz movement in another.

I have had very good luck at the Tesco on Sukumvit in Pattaya.  He is located at the far entrance from where you enter their parking lot.  He stand behind his work with a guarantee.  He even dates a new battery and warranty's it for one year.  If your watch is waterproof like for diving he even has the o-ring grease to reseal it.   

There is a shop just to the right of Tukom, looking at it. He is very good.
