Oyster Perpetual or Tudor Black bay GMT

[Mo_Mo_86]

Newbie here 👋🏻

Just wondering what everyone’s thoughts would be on this scenario...
So I am currently saving and will be saving for a few more years to come for new watch. I currently have a Tag Heuer 2000 Sport Coke bezel as my work/beater, an Omega Speedmaster Automatic 3513.50 as my evening/dress piece as its more polished than brushed in terms of finishing compared to my other two, and my weekend/sport watch is a Tudor Black bay Burgundy ETA that I adore. I would like to add a Rolex to my collection one day. Realistically I won’t be able to go much above £4k and will want to purchase new. Technically that leaves me looking at the OP range, more specifically OP39 and white dial. I do however have a desire to add a GMT to my collection also, but my budget wont stretch to a Rolex GMT MII or Exp II. So my question is..
Do I get the OP39 or if Tudor releases a new Polar or different bezel variant GMT (maybe in a 58 size case too) in the next few years do I get that?
I know it will be subjective to the individual but I am curious to hear your thoughts.

Thanks in advance 👍🏻
