I am new to this forum and not particularly schooled in the world of watches. I'd greatly appreciate advice on this matter. I have a vintage 60s Rado Voyager that needed a new movement because the old one rusted. I took it to a repair shop and the guy replaced it with a movement that he told me at first would be Rado but then when I noticed the color or the day/date was gold and not white (as was the original movement) he said it was not Rado but a comparable Swiss movement. I just noticed when changing the day that the alternate to English is now in Japanese. I also hear a rattling sound when I gently shake the watch next to my ear. I don't remember that from the old movement. I think I got taken. Can anyone shed light on my situation? And if I was taken, what should I say to the watch repair shop?
