Its winding mechanism uses a micro-rotor rather than a complete oscillating weight. The micro-rotor is an art mastered by Hysek and used on most of its creations; ensuring it performs as well as a traditional rotor is a particularly delicate feat of watchmaking.
This feat is very much in evidence here. The micro-rotor is made from a heavy metal, allowing the IO Automatic Manufacture to boast a power reserve when fully wound of up to 62 hours, despite taking up only a very small space within the movement. This allows the latter to be slimmer, whilst also accommodating the large barrel required for this kind of duration. The micro-rotor will also enable Hysek to leave space in the movement for modular or integrated complications to be added. In short, the IO Automatic Manufacture is a timepiece with a promising future, opening up a new creative era for Hysek
