My daughter gave me a Gucci watch, using a battery, to get repaired. In UK a shop estimated Ģ250. In France I established it wasn't a battery problem.
I used this company, http://www.uhrreparatur-online.de/
- they put in a complete new Omega movement, and charged me a total of € 99.
They send you an empty box and an address. You send them the broken watch by DHL. They give you an estimate by e-mail, & you accept, or you pay for the postage and they return your watch. They repair the watch and send you the final bill by e-mail. You pay the bill and they post you the watch back again, by registered post. For insurance purposes, you need a German address, I used LAS Burg at Weil am Rhein, and a DHL depot is just across the road.
I was very pleased with their service! http://www.uhrreparatur-online.de/
