Why three barrels to achieve the eight days power reserve?
The three barrels are exactly what we needed to achieve the optimal stability for the amplitude of the watch for an eight days power reserve. As you know, one of the famous movements used in our watches was the Angelus eight days movement and our legitimacy to create long power reserve watches comes from here. So we worked backwards. If we want to have an eight days power reserve, what is the most logical and robust way to achieve this? It was the three-barrel configuration you see today. How does a GMT indicator express Panerai’s identity? The use of the GMT indicator in our watches is related to the understanding of our client base. The Panerai owner is an adventurer and a traveler. The GMT hand allows for you to always have a sense of orientation, regardless of where you travel. As such, it is in spirit similar to the compasses we’ve created to guide divers through the water at night. Eric Klein, the head of Richemont movements, seems to be particularly inspired by Panerai.
