ISE Movements

The ISE caliber (Irreversible Schwarz Etienne) is an ‘inverted’ self-winding mechanical movement, based on the ASE caliber. Its inversion provides an original unveiling on the dial, its decentered micro-rotor, as well as its regulating organ whose variable inertia balance ensures precision and regularity. Operating at 21,600 vibrations per hour, it offers a comfortable power reserve of more than 86 hours. The properties of the ISE caliber allow it to accommodate various modules with complications including the innovative date revealing system of the ISE 100.01.

Additional information

The caliber ISE101.11 incorporates an innovative date mechanism:
1. The date mechanism is entirely visible
2. The jumper for indexing the date is positioned on a column wheel. This aesthetically superb solution reduces the size of the date disc teeth and increases the size of the numbers for improved readability.
3. The date disc is inclined at 10 ° making it more legible.
4. The date operates through a drive system, equipped with a safety mechanism preventing any risk of breakage (a technique used on perpetual calendars).
5. The quick date correction is performed by a lever with an 'all or nothing/on-off' mechanism to ensure a complete function with each user's pressure.
