I wear only one watch and rarely ever take it off. I currently have a recent-ish Rolex Explorer that serves my needs very well. I like the contrast of the hands against the black dial as my eyesight is not so good any more and the 36mm diameter suits my puny wrists. However, the Rolex is a little sparkly for my tastes and I would prefer something more reserved. An older Explorer is silly money so I started to look around and found older Seamasters that looked as though they might do the trick. As long as Rolex back and screw-down gaskets are replaced and the watch is pressure tested, it matters little how old they are. What is the situation for Seamasters and is there a particular age that I should avoid? Many thanks in advance for anyone's thoughts.
