Rolex Explorer II Trade

[brochris]

Hello Everyone, I am fairly new to this forum but I am in desperate need of help. I have a trade that I am seriously considering and just wanted to get some opinions. I have an Omega Seamaster Planet Ocean XL 45mm version and a Girard Perregaux 1945 Vintage Ref. 2583 that I am thinking about trading for a Rolex Explorer II (White Dial) 2001 Model. I love the Omega but it is just a little too large for my wrists. The 42mm fits perfectly and the GP is a beautiful watch but the resale is horrible; however, I am a little hesitant on giving up the GP just because of the movement; the brands history and the fact that in the "watch world" it is a highly respected brand. Value wise, it seems to be a pretty even trade. The seller is selling the Explorer for about $4000 and he values the Omega at about $2500 and the GP at $1500. Please let me know your thoughts.
