This watch is also known as:
BR01TurnCoordinator , BR01-92TurnCoordinator , BR01-92 .
The watch is based on the turn coordinator found in an aircraft's cockpit - this instrument indicates flight symmetry, without which the aircraft slides or slips.
The turn indicator is a gyroscope used to visualize the rate of turn (roll) and features a bearing that moves in a curved tube to represent the aircraft?s sideslip.
The bearing functions using gravity.
The imaginative watch designers have borrowed this graphic and designed a display that closely mimics that very instrument: there are 3 discs - the upper, larger disc displays the hours, the smaller disc beneath, displays the minutes.
The central disc turns at the rhythm of the seconds.
