I wouldn’t sell either of yours off- those are some pretty perfect specimens and you will regret it after the honeymoon phase with your GMT wears off.
You also have the dilemma of matte dial or the service dial- which was an “upgrade” by Rolex if you ever sent it back to them for any kind of service- they just changed the matte dial to the newer gloss one with the white gold indices wether it needed it or not- and you had no clue until it came back to you. Luckily my ‘83 never went back to Rolex. The matte dial will cost you though.
The GMT’s are in a bubble. Anytime I post a WRUW pic of mine on any forum, I get PM’s asking to sell....it’s nuts. If you’re patient, the market will level back out and prices come down...probably during the upcoming recession (not being sarcastic), so have your gold bars ready to trade.
