I have mine since 1988 and it had about 70% of my wrist time.
In 2004 unfortunately some water entered the watch and I sent it to Rolex for a service.
Only some years later, when I stared to look more deeply into the world of vintage watches, I discovered that they changed the dial. So, mine has a non-tritium service dial.
Honestly, this was very disappointing! π‘
Since then my first glance when I see a 16760 is for the dial and believe me, there are many with this service dial.
Best,
