Hello, I have had an interest in watches and have owned many over the years. Part from a vintage Omega Seamaster Deville this is my first vintage watch. I got this as part of a trade for another watch and my intention is to use it. I do believe that it is in very good nick without any major signs of wear. It looks to be untouched, maybe with the exception of the bezel wich has no signs of wear at all. The gold plating is very good as well as the mineral glass. The lume on the hands is not glowing at all and on the dial it fades within a few seconds. The crown is marked with Heuer only so it should be the banjo type. Unfortunatly it seems to be broken as it easily moves in both directions with the crown flush to the case. What else... The bezel moves and clicks very well and is uni-directional. When it comes to the movement it is ticking, and dat changes are rapid at 12. I have not timed it yet as it has been in my possesion only for a few hours. Firstly I would like give it a basic service but I need some advice from you all to make the right decision and not to make anything I will regret afterwords being a newbie. Now for the questions includin my own thoughts... 1. Is it legit? I do believe that is, maybe with the exception of the bezel. 2. Should I change the crown to the Tag Heuer one? This is where I struggle most. I love the logo but the watch is intended to be used, and i could imagine taking it for swimming. 3. If number 2 above really is needed should I change the gaskets and battery? I think yes. 4. Should I change the hand to new ones? I think no. They look much better as they are together with the aged. 5. Should I change the chrystal to sapphire? Not sure what I think but I am leaning to not do it. Want to keep the warch as original as possible. Thanks for any imput and excuse me for the english as I am from Sweden.
