  1. Hi there,
    For the Schild AS-1130 movement, can you tell me, please, how many turns of the stem detent screw are normally required to allow withdrawal of the stem?

    I wish to remove the movement of one of my watches to align the minute hand, but I understand that if I turn the screw fully counter-clockwise, the detent will separate from the movement and I don’t want that to happen! I’ve tried two full turns but not enough. How far can I go?

    Lovely clear photos, BTW: many thanks.

      • Christian: Many thanks. After 1.5 turns the stem frees up and I lose the ‘click’ between fully in and setting position. I’ll try what you suggest.

  2. How did you tighten the loose hour hand Christian? There is probably a proper technique, but all I can think of is putting it on a firm steel block and giving the centre a very light tap with a flat punch. This is probably NOT the way to do it, so I’d be interested to know how you sorted that. I’ve come across one or two cases of hour hands that just won’t get a good grip of the canon pipe.

  3. I don’t know them, but it seems they make / made decent watches using decent movements. Looks to be not-tiny either despite its obvious vintage?

  4. Not having a famous brand name on the dial would normally send this watch “over the edge”. As you point out both the movement, dial and case are of proper quality, and it is great to see that it got a new lease on life.
    Interesting read!

    Godt arbeid! 🙂
