Yes, as has been mentioned, in your place I would be dying for a chronograph and a sport watch (e.g. diver). But apparently you haven't missed them up to now, so maybe you should stick with your dressy watch theme and branch out to other brands, e.g. a Longines Conquest or a JLC Memovox.

I have always been a big fan of a Speedy Sapphire Sandwich. I know it gets the criticism about not using hesalite but the gorgeous sapphire caseback makes it for me.
I'm dying for a sub 114060 but premium is a no go for me.
Two tone Rolex’s only remind me of Memeber’s Only Jackets, gold chains with chest hair showing and ugly Corvettes.
If you’re not a fan of chunkster sport watches like the subs, the Seamaster 120 is very sleek and sporty and would round out your Omega menagerie. Then spend the rest from dumping that DJ towards a Speedy.
This thread reminds me that I have lived decades past the best years of my life completely unaware that there are people for whom "what watch shall I wear in the pool" is a question they ask themselves. No criticism intended, I just never knew this was a thing.
