As part of its constant quest to innovate and to build on the extraordinary technical prowess of its mechanical watches, BALL Watch Company presents the new Engineer II Magneto S equipped with the revolutionary A-PROOF® anti-magnetic device.
For many years BALL Watch has focused its research and development strategy on improving the anti-magnetic protection of its mechanical watches. The accuracy of a mechanical watch is easily affected by the magnetic fields to which we are exposed almost constantly in everyday life. The briefest of contacts with an artificial magnet may be enough to magnetize an automatic movement and cause the complete stoppage of the mechanism. According to accepted standards in watchmaking, an automatic watch is deemed “anti-magnetic” when its operation can resist a magnetic field of at least 4,800A/m without its accuracy being subsequently affected by more than 30 seconds per day.
BALL Watch unveils its stunning new concept of protection against magnetic fields. Developed and patented by BALL Watch, the A-PROOF® device is a completely new approach to the protection of a mechanical movement. The preservation of the workings of a watch caliber requires it to be enclosed in a casing that protects against the influence of magnetic fields. BALL Watch equips its antimagnetic models with specially constructed stainless steel cases which resist ferrite corrosion. Until now, the anti-magnetic casing has taken the form of a soft iron inner structure, consisting of a rear plate and a ring surrounding the movement and the dial. Soft iron, reinforced by the shape of the inner case, channels the magnetic fields and prevents them from entering the movement, thus avoiding any adverse effect on the accuracy of the watch. This process helped endow the most highly-developed BALL timepieces with anti-magnetic protection guaranteed for up to 12,000A/m.
The A-PROOF® device is based on cutting-edge developments in terms of both materials and construction. In collaboration with its network of leading Swiss industrial partners in the watchmaking and microtechnology fields, BALL Watch carefully selected mumetal – a material never before used in watchmaking – for the development of its new anti-magnetic protection device. Mumetal is an alloy of nickel, iron, copper and molybdenum with very high magnetic permeability, which enables it to attract and deviate static or low-frequency magnetic field lines, against which other methods of attenuation are relatively ineffective. This alloy therefore has anti-magnetic properties which are markedly superior to those of the above-mentioned soft iron and is used to manufacture magnetic shields for industry, research or high technology. Mumetal protects a mechanical watch against magnetic fields up to an astonishing record intensity of 80,000A/m.
In addition to this revolutionary new material, BALL Watch Company engineers sought to bypass the constant imprisonment of the movement in an anti-magnetic cage which renders the caliber mechanism of a watch equipped with a transparent background invisible. BALL Watch Company has thus developed an ingenious diaphragm mechanism that extends or retracts at will by simple circular motion of the bezel. In the fully closed position, the diaphragm locks the mumetal anti-magnetic protection cage. In the retracted position, the diaphragm therefore disappears to reveal the movement at work through the transparent case back of the Engineer II Magneto S. A genuine industrial feat, the diaphragm is also machined in mumetal with a thickness of just 0.06 mm. This feat of precision and technical mastery demonstrates the avant-garde role that BALL Watch Company plays in watchmaking innovation.
Beyond this sensational technical ability, the Engineer II Magneto S boasts a powerful and striking look from the first glance, with a case in stainless steel and a robust 42mm diameter, with a thickness of 12.9mm. The subtle and understated black dial boasts a finely silk-screened graduation. The flange features the main minute markers and is separated from the rest of the dial by a green circle, the corporate color of the BALL brand, which is also used for the second hand. The bezel is perfectly chiseled so as to enable easy manipulation when activating the diaphragm of the A-PROOF® device and only enhances the bold character of the timepiece.
The basic hours, minutes, seconds and date functions are ensured by a BALL RR1103-CSL caliber. This Swiss Made automatic mechanical movement guarantees the model the very best of Swiss precision and quality. The accuracy of this caliber has been certified by the Official Swiss Chronometer Testing Institute (COSC). The Engineer II Magneto S is equipped with BALL’s patented SpringLOCK® system. This mechanism has been developed in-house by BALL Watch engineers to guarantee the accuracy of movement upon heavy shock impact.
The balance-spring is protected by a “cage” designed to absorb the energy created when the watch is subjected to external impacts. Such impacts can cause standard mechanical movements to vary by up to approximately 60 seconds a day. The Spring LOCK® system reduces their effect by up to 66%, thus ensuring that the caliber remains accurate. Watch wearers can now freely engage in various sporting activities (e.g. golf), knowing that accurate time keeping can still be possible under external shock impacts. As is the case with many of the brand’s classic models, the “RR” monogram is delicately marked out at the end of the second hand, subtly recalling BALL’s “RailRoad” heritage. The Engineer II Magneto S is adorned with a strap in Cordura fabrics and a pin buckle.
One of the company’s guiding principles is that a watch should be easy to read both by day and by night. In order to ensure perfect time reading with its mechanical watches even in total darkness, BALL Watch Company uses cutting-edge Swiss technology involving the capture of H3 luminescent gas inside glass micro-tubes on all its models. These micro gas lights are then added to the dial and hands of the watch. The powerful light emitted naturally and continuously by the H3 gas means that the time can be read in pitch darkness. Furthermore, this technology is a hundred times more powerful than other methods of lighting commonly used in watchmaking.
The watch’s exceptional qualities are rounded off by a screwed-in crown, an anti-reflective sapphire crystal, water-resistance to 100 meters and a shock resistance of 5,000Gs. The Engineer II Magneto S is the first BALL timepiece equipped with the revolutionary A-PROOF® device, which paves the way for a new generation of mechanical watches capable of facing the most adverse conditions.
