Whose watchmaker has checked it over?
It’s a 30 year old watch - so the usual cautions apply. A Rolex service is expensive.
How are the bezel, Crystal, crown etc.
I love the model. It was my first Rolex, and I’ve owned a few of them over the years, but the smaller size of crown on these and the older GMT’s, compared to the divers is the reason I no longer own one.
Do you have details of the amplitude and time keeping?
