Grandeur Monocle Aureum

Grandeur

Monocle

The world's first Jump Flap Hour. Four meteorite stones, 335 pieces, each one numbered.

The Monocle hour aperture over the meteorite hour ring
01  ·  The hour

Through an aperture.

One window glides across the meteorite hour ring for sixty minutes. The instant the hour is spent it snaps back, and the next numeral lands whole. Grandeur's patent-pending JumpFlap™ Hour Module, a world first.

The silver guilloché fan and the retrograde minute hand
02  ·  The minutes

Minutes that fly home.

A single hand fans across the silver guilloché sector from 00 to 60, then flies back to zero in the same instant the hour jumps.

Two displays, synchronised inside one module, read as a single gesture.

The meteorite case ring seen from the side of the Monocle
03  ·  The stone

Cut from a meteorite.

Hour ring, case ring and micro-rotor are cut from natural meteorite. The case ring is bored from a solid block of the stone, a world first you can see from the side of the watch.

Every slice carries its own Widmanstätten figure, formed as the metal cooled over millions of years. No two Monocles are, or can ever be, alike.

The exhibition caseback and the meteorite micro-rotor
04  ·  The calibre

Wound by a stone that fell from space.

A re-engineered Calibre 5000A automatic carries the Grandeur module and the world's first micro-rotor cut from meteorite. 28,800 vibrations per hour, around forty hours of reserve.

All of it is on view through the sapphire caseback, with the edition number engraved on the ring.

The Monocle at night, numerals and minute scale glowing
05  ·  After dark

The jump still happens.

Numerals and the minute scale carry lume, so the aperture and the fan glow through the night. On the hour the window flies back, whether or not anyone is watching.

Four stones. 335 pieces.

Aureum, the GPHG entry, in thirty-five pieces. Azuris, Nox Violetta and Noctis in one hundred each. Every dial a different slice of the same fallen metal.

Not an evolution of timekeeping. A declaration.

A jumping flap hour, retrograde minutes and a meteorite micro-rotor, in a case ten millimetres thin.
