The Breguet Tradition Chronographe 7077 separates timekeeping from chronograph operation into two independent gear trains, each with its own balance. That unusual architecture is visible on the dial side, alongside a compact hours-and-minutes display and the chronograph mechanism. This guide explains the layout, the reset-and-arm sequence, and what the currently listed references and specifications establish. It is a technical overview, not a report of personal handling.
What makes the Tradition 7077 unusual?
Breguet describes the 7077 as having “two completely independent gear trains, one for the hours and minutes, the other for the chronograph.” The timekeeping train uses a balance running at 3 Hz; the chronograph train has its own balance running at 5 Hz. Both are visible from the dial side, so the separation that defines the watch is also its central visual feature.
In a conventional chronograph, engaging the timing mechanism can draw energy from the timekeeping movement and affect its amplitude. Breguet’s stated design addresses that interaction by separating the two trains. The Fondation Haute Horlogerie also describes the independent 5 Hz chronograph train. Breguet says its higher frequency enables readings to one tenth of a second; that is the manufacturer’s stated capability, not an independently verified accuracy result.

How the dial and mechanism are arranged
The Tradition collection draws inspiration, according to Breguet, from Abraham-Louis Breguet’s subscription and tact watches. The 7077 carries that movement-forward approach into a wristwatch: the balance wheels sit opposite one another, while the time display and chronograph indications share the open dial-side view.

For the blue-dial version introduced in 2024, Breguet describes a hand-engraved gold dial with a Clous de Paris pattern and white Roman numerals. Hours and minutes appear at 12 o’clock; a 20-minute chronograph counter and power-reserve indication occupy opposing arcs. The current product page describes retrograde indications at 2 and 10 o’clock for power reserve and chronograph minutes, respectively, with the balances at 4 and 8 o’clock. Because descriptions can vary by reference and dial configuration, check the full reference and the specific watch shown rather than assuming every listed 7077 has identical indications or treatment. (Breguet’s 2024 blue-dial article; Breguet product page)
How the chronograph operates
The 7077’s chronograph uses a reset-and-arm sequence rather than simply starting whenever the wearer presses a start button. Breguet describes two screw-down pushers: the pusher at 4 o’clock starts timing; the other stops and resets it. Resetting also prepares the chronograph’s blade spring for the next measurement.

- RACING-INSPIRED DUAL-LAYER DIAL—— Inspired by racing dashboards, the bold dual-layer dial delivers depth and clarity, featuring applied hour markers and a CD-textured chronograph subdial for easy reading in everyday wear.
- HAND-WOUND MECHANICAL CHRONOGRAPH—— Powered by the ST19 hand-wound chronograph movement. This mechanical watch does not use a battery—manual winding is required for normal operation and precise timing.
- DAILY MANUAL WINDING RITUAL—— To keep the watch running, gently rotate the crown clockwise about 15–20 turns each day. When resistance is felt, winding is complete—an engaging, hands-on mechanical experience.
- FUNCTIONAL CHRONOGRAPH WITH TACHYMETER—— Equipped with a mechanical chronograph and tachymeter scale for measuring speed over distance, inspired by classic motorsport instrumentation.
- COMFORTABLE FIT & EASY STRAP SWITCHING—— 40 mm case diameter with a 12.4 mm thickness offers balanced wrist presence. Lug width is 20 mm, paired with quick-release straps (120 + 80 mm) for easy daily switching between styles.
- Reset and arm: Reset the chronograph. This flexes the blade spring, storing energy for a measurement.
- Start: Press the pusher at 4 o’clock to begin timing.
- Stop: Use the other pusher to stop the measurement.
- Reset and arm again: Reset the chronograph to prepare it for another measurement.
For the 2024 blue-dial version, Breguet says the flexed blade spring stores enough energy for up to 20 minutes of timing. The Maison also describes a non-concentric gear intended to smooth torque, a cam-operated stop system for the chronograph balance, and a second stop that halts the balance if there is not enough energy for a complete operation. These are Breguet’s explanations of the mechanism. (Breguet’s 2024 blue-dial article)
Specifications and listed references
Breguet’s current product page identifies the watch as manually wound and powered by calibre 580DR. It lists a 44 mm case, 420 components, and a 55-hour power reserve. The blue-dial article specifies 14.1 mm thickness for the blue-dial version. The current page lists three references; confirm the dial and case metal for the exact watch under consideration.

What is established—and what is not
The official specifications and Breguet’s 2024 technical explanation establish the listed construction and operating concept. They do not establish a writer’s personal handling or a measured on-wrist experience, so this article makes no such claims. Nor do those specifications amount to an independent test of the tenth-second reading capability. The 7077 is best understood here through its documented architecture: two visible, independent trains, distinct balance frequencies, and a chronograph whose reset also arms its stored-energy spring.
