i like all mentioned and additionally the "landau'? triple date? The IWC would be my top pick but judging by the bouquet of watches he has you and your sis are not dealing with a novice so prices might be shocking 😁
I like that Landau triple date Moonphase if it is dirt cheap, even though it looks like it might be chromed case.
Agree on the Eberhard looking interesting.
PS you’ve got a cool sister, my brother is in Switzerland right now I wish he would explore fleamarkets for me !
The Yacht Club seems to have a broken second hand. Raises a red flag for the dial. What else damage is caused by a clumpsy ”watchmaker”?
I'd get every one of them checked at a watchmaker if any of them is 50€ or more...
