I have a 2000 Link Quartz (model WT1110.BA0550) with the Black face. I've attached a picture. I would say it is in fair/good condition for being 15 years old. It retailed for $1,695 in 2000. Does anyone have an idea what this watch might be worth these days?
According to actual sold prices on eBay (as opposed to asking prices), anywhere from £270/$420 - £515/$800 depending on condition. Those going for the higher prices were described as "mint" or "immaculate". You can check yourself by searching for "WT1110" on eBay and selecting "Completed Listings" only.
