The characteristic Léman case features curved lugs and a rounded, layered bezel. Due to the various crowns and controls, the watch has a distinctive technical character.

The case shows signs of use and hairlines, with somewhat more noticeable superficial scratches on the polished parts. The shapes of the case and lugs remain clearly recognizable.

These are particularly visible under certain lighting. The dial remains clearly legible.

Dial

Black dial with:
- Large Arabic hour numerals
- Luminous hour markers
- Broad luminous hour and minute hands
- Central second hand
- Date window between 4 and 5 o'clock
- 24-hour/GMT indication
- Mechanical alarm display
- Small seconds/function display
- Minute scale along the outer edge
- BLANCPAIN signature at 6 o'clock

Réveil / mechanical alarm function

One of the key features of this Blancpain is the mechanical alarm function.

Unlike an electronic alarm, the alarm signal is fully mechanically driven by the movement. The alarm time can be set separately and the dial includes its own indication for it.

This makes the Réveil GMT considerably more complex than a conventional automatic Léman.

──────────────────

GMT / second time zone

The watch also features a second time zone.

The 24-hour indication allows reading a second time and distinguishing between day and night hours. This is particularly practical for travel or tracking a time zone elsewhere in the world.

──────────────────

Movement

Blancpain automatic mechanical movement.

Through the transparent case back, the movement is visible. The rotor bears Blancpain signature and the “JB 1735” logo. The movement features a refined high-quality finish with blued screws and decoration on the rotor, bridges, and plates.

The mechanical construction combines normal time display with date, second time zone, and alarm function.

Frequency: 28,800 semi-oscillations per hour.

Timegrapher measurement

Measured deviation: +6 seconds per day
Amplitude: 295°
Beat error: 0.2 ms
Lift angle: 52.0°
Frequency: 28,800 A/h

The measured values show, at the time of testing, a neat amplitude and a small beat error.

A timegrapher measurement is a snapshot in one testing position and does not guarantee future accuracy or full technical condition of the movement.
