I can answer without photos.
This is a 1927 art deco period Ball/Hamilton size 16s
open face gold-filled (not gold) railroad pocket watch
with a 21-jewel, grade 999p movement. The value of
this watch is $525 to $600 retail.
Some sites that I recommend for selling are Offerup.com (local), Varagesale.com (local) , Wanelo.com, Bonanza.com, Ioffer.com, Etsy.com,
Ebay and letgo.com (local).
You can also go to invaluable.com or liveauctioneers.com and search their directory for an auction house near you and consign to them.
