    You need to pull off the hand first. it is a press fit. You almost need a special puller so as not to damage the thin dial. There is a recess in the center that dose not support the dial. Then the dial lifts off and the retaining screws will be visible. It is a while since I last opened mine.

    i have removed the hand but the face (dial) does not lift off. the bezel and the face plate turns in unison to set the vernier to zero before use.

    The "thin dial" that you are referring to is the face plate or the hand?

    Sorry , there is a retaining ring around the edge of the dial that need prizing out. The dial plate is thin.

    I have a digital caliper.
    My late fathet left this for me. Its still very accurate. Ir needs a crystal replacement. Probably keep it after cleaning it and put the crystal back. Any help is much appreciated.

    I am going from memory. And looking at the drawings in your duplicate post , i suspect the dial plate is held on to the body with glue/double sided tape. I would put a small hook tool through the hand hole and gently pull. You should be able to see where the dial is attached by the flex in the dial. A little warmth from a hot air gun(just warm,not smoking hot) might help the glue to let go.

    Looking at the spare parts, the dial is not glued on. The outer circumference has locating tabs to keep it in place. i believe the aluminium knurled bezel is heated to expand and slipped over the bottom piece thst is mild steel. when things cool down, the bezel grips tightly agsinst the bottom piece of mild steel and they rotste as one unit.

    Push the bezel from underneath.
