7-DAY POWER RESERVE
We are remarkable for offering several models with a 7-day power reserve, a valuable asset in a mechanical watch of this calibre. This is achieved by the use of two barrels in the movement. The actual winding springs are made from the unbreakable and self-lubricating material Nivaflex. Our power reserve indicators are on the movement side of most of our watches, visible through the sapphire crystal case-back.
