It’s a very nice watch Mick, and the lack of overall Zenith movements supplied tomRolex meant that more were put into gold and bi-metal cases at that time, so partly responsible for the success of the current Daytona!
There are are lots of reasons for keeping hold of a watch - obviously the best one being that you enjoy wearing it a lot, but I have a lot of watches I no longer wear and have no intention of selling.
Hipe you enjoy it over the next couple of weeks - I think I’ll take out something I haven’t worn in a while :)
