Rolex Submariner No date perhaps? Anyway, > 4k US$ ...sorry.
Great watch, classic, great resale value.
'below' such a Rolex, I 'd go for a Omega Seamaster as well.
Tag Heuer isn't that bad. My first expensive watch(1000,- guilders!) was a Tag Heuer in 1986 , a 1000 quartz.
BTW my old man is a professional watmaker for over 40 years now . His favourites are Rolex, JLC and Patek.fwiw.
I also like the Oris divers collection.
