I tried selling my skeleton watch and got nowhere

Skeleton watches are a hard sell secondhand. The market is smaller than for regular dials. Most buyers want something they can read at a glance. i've had better luck selling to enthusiasts directly than on general marketplaces.

What brand and what price range are we talking about? That makes a big difference.

Photos matter a lot with skeleton watches. Flat lighitng makes them look like a jumble. You need strong directional light and a macro shot of the movement so buyers can see the finishing. Most listing photos I see are terrible.

Fourteen hundred for a two thousand dollar skeleton is going to sit. Skeletonized pieces depreciate harder than solid dials because the appeal is visual and subjective. Buyers who want that look often just buy new.

Agree with NineVolt. Also the 'is it broken' questions never stop. The open movement confuses casual buyers. Try a watch forum classifieds section instead of the big general sites.

Did you include a video of it running? That helped me sell a skeleton once. A ten second clip of the balance wheel moving kills the broken question immediately.

Good point on the video. I'd also add service history if you have it. Skeleton movements are delicate and buyers worry about prior work.

Honestly at fourteen hundred I'd rather put that toward a new one with a warranty.Not saying your price is unfair, just that the buyer pool for used skeletons is thin.
