Measuring elapsed times provides immediate visualisation of the desired function, but making it work is an additional mechanical challenge, because starting a chronograph disturbs the main gear trains. To alleviate this problem, Breguet has fitted its new Tradition Chronographe Indépendant 7077 model with two independent trains.

The first is the going train for the hours and minutes, regulated by a 3Hz balance and having a power reserve of 50 hours. For the chronograph, the second transmission has a 5Hz frequency to ensure more precise readings.

Normally, a second train implies a second barrel to provide the energy required by the chronograph. This approach nonetheless needs more space and above all means that the owner of the cheap replica Rolex watches must wind up the chronograph barrel spring as well as the going barrel. With the Tradition Chronographe Indépendant 7077 model, Breguet has introduced a new type of spring. The energy required to drive the chronograph is provided by the user when operating the reset-to-zero function. This energy is stored in a flexed blade spring. The system enables the user to start the chronograph instantly, without worrying about the energy available, because it will always be at its maximum.

The application of the blade spring principle by Breguet’s watchmakers has given rise to a number of innovations. A non-concentric going train has been associated with the blade spring so as to even out the torque and achieve constant amplitude and rate of the chronograph. A patent has been filed for the entire spring and train assembly. Instead of following its usual curve, the shape of the train has been calculated to transmit constant force to the chronograph.

In addition, the reference 7077 is fitted with a patented chronograph balance-wheel in titanium ensuring perfect symmetry with the movement balance-wheel. The two balance-wheels are the same size, despite their different frequencies, and their position is in tune with aesthetic considerations.

The chronograph function of this Tradition model is controlled by two pushers that are screwed in to keep out water: one pusher is devoted to starting the measurement, while the other stops and resets the chronograph to zero. It is this zeroing action that flexes and arms the blade spring, thus preparing the chronograph for a new measurement.

The titanium balance-wheel is also flanked by two brakes. The first, working off a cam, frees the balance-wheel when the chronograph is started and then holds it when the chronograph is stopped. In this way the balance-wheel is always in the ideal position and instantly reaches its proper amplitude. This innovative mechanism is protected by patent.

Among the features that recall the historical roots of the Tradition collection are the patented pare-chute anti-shock devices as well as the chronograph control which recalls that of the reference 4009 double-second observation timer sold by Breguet on January 6th 1825.

The style of this Breguet Tradition Chronographe Indépendant 7077 is noted for its symmetry. The engine-turned dial in silvered gold showing the hours and minutes is offset at 12 o’clock, while the chronograph hand is fixed in the centre of the cheap Rolex watches. The chronograph-activation indicator is at 6 o’clock. Directly opposite each other at 2 o’clock and 10 o’clock two retrograde hands respectively indicate the power reserve of the cheap replica watches and the chronograph minutes, while the two balance-wheels beat side by side at 4 o’clock and 8 o’clock.

This hand-wound timepiece is water-resistant to 3 bar (30m) and is fitted with a leather strap.
