I'm in a hunt for PAM651 but they are pricey as hell.
Also, there's plethora of beauty vintage art deco desk clocks from Cartier, JLC, Chopard etc.
And just yesterday I found an extremely cool example from VC that I had no idea about (it's a link to the auction I was checking). See lots 53 & 97-99.

If you have a pocket watch there's nice choice of cool stands that make them basically desk clocks
