Since I was able to take apart and successfully put together again the two Chinese Unitas based movement, I decided to be brave and try my hand at an actual Unitas movement. Since I have this old Unitas movement, which I got from buying two old watches off the Internet (the other movement is an AS movement), I thought I try working on this movement.
The movement is the Unitas 6325. This an old movement, introduced in the 60s or 70s. It is a 17 jewel movement. There is a 21 jewel variant, but I have the 17 jewel version. It beats at 21,600 A/h and measures 13 ligne. It is a manual wind movement and has a power reserve of about 48 hours. The movement offers the following functions; hours, minutes and small seconds (sub-dial at 6 o'clock position).
I will be posting the removal pictures soon (again as a reference), but for now, the movement in pieces.
The bottom plate.
The barrel bar, ratchet wheel, transmission wheel, click, click spring and center wheel.
The crown, stem, pallet and pallet cock.
The escape bar, escape wheel and 4th. wheel.
The barrel, cover plate, return bar, crown wheel, castle wheel, pull-out piece and screw (one-piece design), return spring and 3rd. wheel.
The movement is in bad shape and in need of a good cleaning. I have done some cleaning with Rodico, but I don't think that is the correct method. I will be talking to my friendly watchmaker and see what is his advise on the tools that I need to do a proper cleaning of the movement. I will also need to lubricate the movement once cleaning is done. Further advise will be sought.
