Another great watchismo find.
This somewhat indistinguishable wristwatch has a very special feature, the hidden compartment containing a scroll on rollers under the dial and movement. By pushing a little release button at the bottom of the case, the watch opens up to reveal the notepaper rolls which can be adjusted by two roller knobs.
