Case features


The first views of the calibre once the case back is removed.

The movement is held in the case through the tension created by two screws pushing the movement down towards the bezel. To remove the movement, the stem is first removed and the screws loosened so as to allow the movement to be turned until the screws aline with a cut out in the case which frees the screws and the movement to be extracted.


The stem is released by pushing on the button in the centre of the image.

The button is part of the setting lever on the under side of the movement holding the stem in place and linking to the setting mechanism.


The crown tube is screwed into the centre of the case with a star shaped key. Inside the tube is a further rubber seal.

The triple lock crown screws down onto a tube which has seals on the inside and well as a seal on the outer surface. There is also a seal on the bottom of the inner surface of the winding crown.


Once the movement is removed from the case the stem is then returned to the movement for dismantling.
