GS looks kinda fun / different but not totally out there
Agree above it might not make total financial sense but then let’s face it the only sensible financial choice re watches was to buy 50 subs 20 years ago
Value might not be massively different, depending on condition, but the number of people looking to buy a BB58 is likely a lot greater than an SBGN027. I'd say it's only worth it if you fancy trying something different for a while. If you're looking to move it on I wouldn't bother.
Do it
