is the SBGN027 new or used? And is the goal to raise funds asap or not? GS is still more niche than Tudor (and high end quartz, prob more so again) so I'd have thought if cash release was the goal, the Tudor is more "liquid". You could ask Subdial or Watchfinder what they'd offer for the GS and for the Tudor for a quick comparison?
A quick look on Chrono24 suggests you can get a new GS for around £2.4-2.5k without much fuss so I suspect any second hand one is going to be worth less than your 58....
