Sportier expression, the Marine Chronograph 5527 enriches the collection with a "flyback" chronograph function. The seconds are measured by means of a large central hand, while two counters, arranged between 3 and 9 o'clock, display the chronograph minutes and the small seconds respectively. This architecture preserves the legibility of the dial while infusing it with greater rhythm. Seconds display The seconds display makes it possible to follow the passage of time with precision. Depending on the construction of the movement, it may take the form of a central seconds hand or an off-centred small seconds display, integrated into the architecture of the dial. Chronograph The chronograph makes it possible to measure short intervals of time with precision, independently of the time display. At Breguet, this complication is part of a pursuit of performance, legibility and mechanical reliability. Calendar The calendar displays the date on the dial, generally by aperture, hand or disc. Simple in appearance, this indication requires precise integration both into the movement and into the balance of the dial. Bevelling Bevelling consists in chamfering and then polishing the edges of the movement components. This finish highlights the contours of the parts, catches the light and reveals the precision of the work devoted to the smallest details. Stretching / dressing Stretching and dressing prepare or finish metal surfaces through the regular working of the material. These operations create clean, flat and even surfaces, essential both to visual quality and to assembly precision. Guilloché Engine-turning engraves regular patterns into the material using a hand-operated lathe. At Breguet, this expertise structures the dial, catches the light and reinforces the legibility of the indications. Straight stripes Straight stripes are a decorative finish formed of regular parallel bands on the movement components. They structure the surface, soften reflections and highlight the geometry of the bridges.
