Hello Phillipe and welcome!
Page 456 of "OMEGA A JOURNEY THROUGH TIME" (AJTT) shows a very similar clock, case and movement.
However, the Chinese lacquer dial shown is not as detailed and ornate as yours but is in the same style.
Researching the movement, it is either the 59 8-D SCS CLEF bull 20 p or the 59 8-D SCS T1 CLEF bull 20 p.
Movement was built in the mid-40's (44-47) but could have been cased and sold years later.
Very beautiful, but not really to my taste as I was in the Army and this is more a Navy man's piece!
Joking aside, quite a nice clock!
