Hi all,

I’m going to service a recent acquisition, this Marti four glass clock, or crystal regulator. As it’s been a while since I last took one apart, I can’t remember how to go about getting the movement out once I’ve removed the screws from the mounts on either side, as it would appear that the screws for the third mount, above the movement, are obscured. I presume I have to deal with the screw in the second picture to get any further, am I right ? If so, how can I loosen it given that a screwdriver goes in at an angle? Thanks for your input, photos attached.

Best regards,

JJ

I think you undo that bottom center screw, at which point the movement will rotate. You can see some squarish posts, as well as some notches in the back plate. Line those up and it should pop out

Think I'd just take the case apart and then remove the movement from the frame.

That is correct. No need to remove the bezel. I did this once and found later it wasn't necessary. The movement is attached like a bajonet.

I take the hands off and get needle nose pliers and pull the three or four tappered pine out that hold the movement to the dial and pull our the movement.

Many thanks gents for the good suggestions. In the end, I decided to investigate and see what the purpose of the screw I mentioned was. As I had hoped, it allowed me to remove the top cover of the clock, giving me access to the third set of mounting screws underneath, and then to slide the movement out without dismantling the case. Problem solved!

Regards.

When you start taking the movement apart you will see that the easiest way to remove it from the case is the one described by Bruce in post #2. No need to remove any parts of the case or bezel. It makes it also easier to put it back in.
