I was offered by my local reseller to buy a steel 41mm Rolex Submariner never worn with a black dial for $13,500 (126610).

I went to the Rolex official store in Qatar and was offered to buy at the store two options of a rose gold 41mm Rolex Datejust chocolate dial jubilee band:
- without diamonds ($15,500)
- with diamonds on the dial ($17,500).

What should I buy? Any other recommendations are appreciated as well! As I understand classic black dial Subs holds value better and the bicolor Datejusts are not as good, but I like that Datejusts look smarter, because subs look too sporty for me. I’m leaning towards more formal watches.

Thank you!
