Used no box or papers on this. 222.60.46.20.01.001 OMEGA SEAMASTER Planet Ocean http://www.authenticwatches.com/omega-planet-ocean-22260462.html A friend of mine wants to sell this & I can not find a used price anywhere for it. Want to make him a fair offer but tough when there are no comps to evaluate. Is this watch that rare in the market? Thanks guys I appreciate it.
