I am worried that my Constellation does not cope well with water. Am I thinking wrong when I use it together with a Rolex Sea-Dweller for protection? I have noticed that the rose gold seem to be a bit soft in contact with the SD but I am more worried about the water. I have had success earlier when using a Seamaster 1000m together with a Flightmaster. It seem like the Seamaster is soaking up the humidity and saves the Flighmaster. I got this advice from a watchmaker - If you are worried about the water resistance - do get another watch to solve the problem. Is he right? I feel insecure.
If I understand your watchmaker correctly, I think you are supposed to buy an Invicta, and put the vintage watch inside the Invicta.
