Among Haas's unconventional pieces, double‑sided pocket watches are the most notable. The present lot is one of them. The front dial shows moon phase and basic timekeeping. The back with a semi‑skeletonised annual calendar, that is a Haas signature. The lever slide for activate minute‑repeating is on the band of the pink gold case. The bow has an additional function: when folded the bow to one side, the cover of the opposite side can be opened by pressing the pusher to the crown.
