So, the original trader contacted me again, willing to continue negotiations for the Mark II.
Additionally, I've been contacted by another potential trader to trade for a 2254.50. I think this trade would require some cash on my end. I've wanted an " Electric Blue " Seamaster for a long time: there are a few titanium and stainless models with the Seamaster and Speedmaster bracelets that I would love to get. However, the 2254.50 is a classic.
