This is an extremely rare Universal, UFO watch, known more elegantly as the "Prince" and offered at two very high end jewelry stores circa 1936. Above pictured in an Hermes advertisement and lacking a Universal Geneve signature on the dial, and in the OP, pictured with the co-signed dial with Boodle & Dunthorne, Liverpool.
Gilt on black dials were quite unusual as well, offering a nice contrast for what appear to be gilt hour markers and solid gold leaf hands.
While Hermes and Universal were known partners, this is the only example of a Boodles watch that I have ever seen, having searched through everything in my database and on the net.
Can anyone in the UK direct me to a newspaper or other archive that might contain an original Boodles Ad for the watch, circa Christmas 1936?
