Anton Suhanov Racer Jumping Hour GMT

Creator of the first Russian triple axis tourbillon table clock, Anton Suhanov is an award winning watch maker. His Racer Jumping Hour GMT watch takes inspiration from the sports car dashboard. Some dashboards come with a tachometer on the left, a speedometer on the right side, and some additional indicators and numbers between them.

For the Racer Jumping Hour GMT watch, Anton Suhanov developed a unique dial structure featuring two retrograde hour and minute subdials. They are located on the left and right and slightly shifted down — exactly for one position on the hour scale of the dial, while the remaining central part of the dial is given away to other pointers.

The unique layout of the dial also spotlights some features inspired by the legendary “Marie Antoinette” pocket watch. Made by Abraham-Louis Breguet, this historic grand complication watch has two retrograde subdials of date and equation of time.

For the Racer Jumping Hour GMT watch, Anton Suhanov built a caliber with the indications based on the function of the retrograde indication of minutes.

At the beginning of a new hour, the minute hand jumps from the 60-minute to the zero position. This swift movement performs two actions: it switches the retrograde hour hand forward one hour, and then the hand remains motionless for an hour. This is exactly how behaves the hour hand of the “Marie Antoinette” watch.

And at the same moment the 24-hour digital second timezone indicator of Racer Jumping Hour GMT, installed in the window at 12 o’clock position, goes one hour ahead.

In the center of the dial, there is an unusual second’s indicator on a dynamic 20-second arc-shaped scale. If you take off the watch dial, it turns out that the seconds are indicated by a three-rayed second hand, similar to the one that was installed on the tourbillon axis of the foundation Black Clock. At the bottom of the dial, there is a date window.

The watch is equipped with the Su100.20 self-winding movement based on the ETA 2824-2 calibre. This horological engine also powers the innovative indication module developed by Anton Suhanov. The movement has a power reserve of 38 hours.

The indication module of the Racer Jumping Hour GMT is very complex. Comprised of 172 parts, it is comparable to classic horological complications as a perpetual calendar or minute repeater.

The watchmaker treated every detail of the movement and module with utmost care, using traditional techniques, including manual polishing of chamfers, engraving, polishing of recesses for screws, pins, and stones, spherical polishing of the shafts of the wheels and pins, perlage, fine straight, and circular grinding, sand-blasting, rhodium plating. The dial is finished using the anodizing, ruthenium coating, and guilloche.

The Anton Suhanov Racer Jumping Hour GMT watch has a 39mm diameter case made of stainless steel.

The unique design of the case is based on the principle of the regular Reuleaux polygon. This shape can be briefly described as a square with rounded sides. This shape hints at the aerodynamics, streamlined lines found in high-speed cars.

The other highlights of Racer Jumping Hour GMT include double screws for fixing the bezel, paired screws for the pads of the axes of the retrograde hands, plates with inscriptions and a scale of seconds, the double knurling on the crown and the whimsical shape of the conical holder of the button for switching second timezone indicator.
