Buler lcd digital 1970's watch

[liger03]

Can someone please tell me if I can get a replacement movement for a
Buler Ladies lc quartz digital watch from about the 1970's. I have a module number on the instructions of SSIH 4315. If they are obsolete is there any other movement that would fit. With thanks

Take picture showing the button positions and measure the diameter of the inside of the case in mm. Probably 25 or 20.
