Ball Watch Engineer II Magneto S With New Antimagnetic Technology

At Baselworld this year, Ball Watch Co. announced the Ball Engineer II Magneto S, a new mechanical watch with a patented magnetic protection system. Ball s new technology, known as the A-Proof device, shields the movement from magnetic fields up to 80,000 Amperes per meter (A/m).

Magnetic fields are a real danger to mechanical watch movements. The effects of even a relatively slight magnetic force can throw off the timekeeping of a balance. When a movement has gone through a magnetic field, it may start to gallop, changing almost overnight from even timekeeping to excessive speed. To that end, watchmakers have employed various technologies to protect movements. Usually, for a watch to be considered anti-magnetic, it must be able to withstand a 4,800-A/m magnetic field and gain or lose no more than 30 seconds per day. The usual method of protection C and one that Ball Watch has used in the past C is to shield the movement in a soft iron cage. This protects the watch up to 12,000 A/m.

The Ball Engineer II Magneto S rethinks the materials used to guard against magnetism. Inside the Magneto s stainless-steel case, the movement is surrounded by a shield made of mumetal : an alloy of nickel, copper, iron, and molybdenum. Known as the A-Proof device, this substance shields the watch up to 80,000 A/m. Ball Watch replica hublot big bang uk calls this a completely new approach to the protection of a mechanical movement.

Although A/m measure a different magnetic field than Gauss do, the 80,000 A/m that the Magneto can sustain is roughly equivalent to the 1,000 Gauss that the Rolex Milgauss is known to protect against.
Additionally, Ball s Magneto includes an exhibition caseback, which has not been possible in traditionally protected anti-magnetic watches. A diaphragm mechanism underneath the sapphire crystal caseback can be irised open or shut by rotating replica omega seamaster planet ocean the bezel. When it s open, you can see the movement, and when its mumetal plates are closed, the http://www.hhibt.com/cheap-panerai-luminor-uk.html caliber is entirely protected.

The Engineer II Magneto S has an automatic RR1103-CSL movement. It is COSC-certified as a chronometer. To protect it against shocks up to 5,000 Gs, it also uses Ball s patented SpringLOCK system. It is water resistant to 100 meters. For timing, it has a standard three hands and a date window at 3 o clock. The stainless-steel case is 42 mm in diameter, and has a screw-down crown. The watch comes on a black cordura strap. The price in Swiss francs is 2,900.
