I would like to recommend you to plan a visit in Geneva to visit this great exhibition, presented under appointment, by Jerôme Maier.
Thanks to him and to Véronique Briand. I enjoy all his explanations and the 1 hour visit tour.
Here is the leaflet
Travel table clock with alarm clock in the smaller sub-dial. I like the hands +++
First HU "Heures Universelles"

then large second hand to coordinate officer's pocket watches to the Marine chronometer fixed on the Boat command cabin.

Then new case in inoxydable steel
and Overseas collections starting with 222 in 1977, Overseas 1 in 1996, Overseas 2 in 2006 (presented) and Overseas 3 in 2016 (not exposed).....
