Use the minute’s hand to set the time. Make the hour jump as many times as necessary by turning the crown upwards to activate the retrograde minute. Setting the minute’s hand can be done clockwise or counter clockwise, but you must respect the following guidelines: – When the minute’s hand is located between 40 and 60 minutes, setting the time counterclockwise is possible only up to 25 minutes. Beyond this position, the hour disk will shift and the counterclockwise setting of the minute’s hand will be blocked. In that case, only a clockwise setting of the hand is possible, and the hour disk will go back to its central position. – When the minute hand is at zero, an anticlockwise adjustment will cause the hand to disconnect from the mechanism to protect the mechanism of the watch: the minute hand will jump to 10 and come back to zero. The hand is disconnected, and the counterclockwise adjustment will not harm the mechanism. To reconnect the minute hand to the movement, turn the crown downwards: the hand will jump to 10 then come back to 0. The hand is reconnected, and you can now set the time clockwise and counterclockwise.

When the watch is stopped and the hand of the power reserve of the watch shows the power reserve has run down, manually winding the mechanism by winding the crown upwards allows to put tension into the mainspring and restart the mechanism. When it is worn, the watch winds itself constantly thanks to the rotor. You can see the level of the power reserve thanks to the hand on the power reserve indicator. The horizontal line in the last zone of the power reserve indicator shows the power reserve is exhausted. In that case, you must wind your watch manually. When doing so, the hand of the power reserve indicator will progressively go back up to the maximum graduation. NB: on the Tiefenmesser model, the power reserve is displayed on the round openings at the bottom of the dial. Each opening corresponds to a graduation. When only the last opening remains red, it is necessary to manually wind the watch.

For the timepiece with the date only

This position allows setting the date by winding the crown upwards only. If you rotate it the other way, the crown won’t change the date. To preserve the watch’s mechanism, the automatic change of the date does not operate simultaneously when the retrograde minute jumps from 11:59pm to 0:00am. The date change happens between 12:00 am and 01:00 am.

On some of our models, the 316L steel of the case and/or of the butterfly folding clasps is coated with PVD (physical vapor deposition). This is a surface treatment method used in the horology industry to achieve tinted metallic coatings with a high resistance. PVD being a coating material, it is possible that the stainless steel under the PVD arises in case of shocks, deep scratches or regular friction. The warranty does not cover such cases, inherent to all coating materials.
