Thoughts on a potential trade

[StairLight530!!]

I recently bought a BLNR on an oyster band from my authorized dealer (AD). While it's a great watch, I'm beginning to feel like it overlaps too much with my Sub 41 Date and black ceramic Daytona.

My realtor has expressed interest in buying the BLNR for $18,000. I'm considering selling it, recouping my money, and potentially getting the new Air-King for free with my AD's help within the next month. My friend has an Air-King, and I borrowed it for a few weeks and enjoyed it.

I understand the Rolex community may not be fond of these kinds of questions, but I'd appreciate some input. Would you make this move? Essentially, I'd be getting an Air-King for free with this decision.

My current collection includes a Sub 41 Date, a black ceramic Daytona, a Speedmaster 3861 Hesalite, and the BLNR on an oyster band.

What do you all think?
