Watchmaker Martin Braun, who recently started the brand Antoine Martin, has come up with a new concept that is contrary to what everyone in the industry is doing. Instead of building a watch with one of the most common frequencies: 2.5Hz (18,800 vph), 3Hz (21,600 vph), 4Hz (28,800 vph), or with a high frequency such as Zenith’s 5Hz (36,000 vph) or Breguet’s 10Hz (72, 000 vph)– he made a watch that oscillates at the slowest frequency possible – 1Hz (7,200 vph). It literally runs slower than any other wristwatch in the world.
By drastically reducing the frequency to 7,200 semi-oscillations (vibrations) per hour or 1 Hz, it would seem that the watch loses accuracy, however, Antoine Martin has figured out a way to offset the lower frequency by incorporating a giant 24 mm diameter balance which generates so much kinetic energy that it cannot be disturbed.
Furthermore, as a result of the slower rate of oscillation, the second-hand jumps more distinctively than a higher frequency watch. So, you can see the second-hand advance in two jump increments every second.
