Just won a Rolex - which should I choose?

I just won a sales contest at work and they are giving me a $20,000 budget to go pick out any Rolex I’d like.

I currently own a Breitling Navitimer (steel, blue face, leather), Breitling Superocean (steel/rose gold, black face, silicone band), and an Omega Speedmaster (steel, black face, steel bracelet).

I do not know the Rolex brand well as this will be my first Rolex.

Watches I’m finding in that $20k range are a two-tone Sea Dweller, or two-tone Sky Dweller. I really like the look of both.

I am a taller guy and have large wrists and like the larger, chunkier watch size.

(Note - I’d like to maximize the $20k budget. If I spend $14k I don’t get to keep the extra $6k)

Would love to get anyone’s thoughts! Which is the more sought after watch? Which is the more impressive watch? Which holds best value for investment for my family?

What Rolex would you buy if you were handed $20k?? TIA!!
