Advice on pricing used 14790ST

[edlorpi]

All, I would like to ask your assistance in pricing a watch I am helping my employer sell. The watch has been worn and used. Unfortunately the box, papers, manual have been discarded. I did have him pay for a certificate of authenticity from the AP Boutique on 57th St in Manhattan / NYC.

The model number is 14790ST.OO.0789ST.09, E-series - Caliber 2225 36 Jewels, and described as Dark Blue Big TAP. AP 10 Index Dial, stainless steel case and bracelet with 11 links at 12h and 7 links at 6h - and no spare links, appears to be sized for 6.5" wrist.

He has the travel case (or is it AP service case?) and the certificate of authenticity as well as the receipts from AP for the watch with serials for both the watch case and the movement noted. The watch has not been repolished, runs and keeps time properly, winds without issue. I don't know if it has been serviced or not so I'd guess not. I'm told he acquired the piece in the early 2000's.

What would be a fair asking price for it? He believes it isn't worth his time selling and was quoted in the $3-5k range. I'd like to help him sell the watch.

Thanks for your help!
