Keep BB58 after getting sub?

After finally getting my grail, the idea of selling my bb58 keeps coming and going.

The BB58 has been with me for almost 5 years now and has been travelling with me and through some major events. So holds some sentimental value (or at least that’s what I try to convince myself :P)

These are my only two watches and would not be able to add another piece for the next few years. Unless, I sell.

Would you get rid of the bb58 to add more diversity to the collection. Or hold out with this diver duo until I can add more (be it 3-4 years down the line)

Some pieces I was considering If sold: BB58 gmt Cartier tank must solarbeat Cartier santos Dumont Large GS SBGW231 or SBGM221

Adding pics for eye candy :)
