Help: What would you choose next?

[subdownunder]

I have a problem, a nice problem but a problem all the same.

My current collection of watches consists of:

Rolex GMT Master ii (2009)
Rolex Explorer 2 Black face (2020)
JLC Reverso 976 (2013)
JLC Master Calendar Moon Phase (2019)
Omega Speedmaster (hesalite) (2019)
Tudor BB58 Navy Blue on steel
Omega Speedmaster reduced Mark 40 White face Japan Special (1995)

Now my problem.

My son who recently graduated wants to buy me a watch ($10K'ish) as a thank you gift for supporting him through University.

He is buying this mum an LV Bag (easy). but I cannot think of a watch I want at this time that will both compliment what I have collected or fill a gap.

Can you help me explore the options by suggesting what you would choose and why?

Many thanks
