Breguet’s watchmakers paid particular attention to the styling of the Classique Tourbillon Quantième Perpétuel 3797 watch for a more intuitive display of the indications. The amount of information displayed on the dial can be confusing, so Breguet has added a third dimension. By lifting the hours and minutes chapter to the foreground, the timepiece draws attention to the essential information. A further glance takes in all the other indications. The reference 3797 does this with an offset sapphire disc. The opaque chapter ring with its metallic Roman numerals reveals the time instantly with the aid of the Breguet open-tipped hands in blued steel. Beneath the disc, an engine-turned hobnail pattern decorates the dial, overarched by the semi-circular scale of the retrograde dates.
The one-minute tourbillon at 6 o'clock complements the chapter ring. This complication proved difficult to construct because it is mounted on a slight dome. Despite the curve, its bridge is delicately chamfered and surmounted by a triple hand for the seconds. The subdial for the days at 9 o'clock is engine turned in waves. In the movement, a snail cam makes the days hand jump instantaneously. At 3 o'clock a blued steel hand points to the months on a dial engine-turned in a shimmering sunburst pattern. At its centre a blue sun shows the leap years.
At the back of the watch, a sapphire-crystal glass reveals the movement and the way the baseplate has been designed to throw the maximum light onto the tourbillon. The engravings thus give life to a trellis that seems to jump out of the movement, while the tourbillon’s ballet sets the tempo. The cases, in rose gold or in platinum, are finely fluted around their sides and the lugs are welded on. The engine-turned patterns, the unique number, hands in blued steel and the secret signature complete the features that identify a Breguet watch.
