Henri Grandjean Rose Gold & Blue 5N rose gold case with polished finishing

The Case

Sculpted in 5N Rose Gold

The case is crafted in 5N 18K rose gold (Au750), chosen for its depth of tone and material stability. Its warm hue provides a measured counterpoint to the technical complexity of the movement, reinforcing both presence and balance.

Rose gold dial with blue hour indexes

The Dial

5N Rose Gold

Executed in 5N 18K rose gold, the dial offers a uniform, softly reflective surface. Blue-coloured indexes introduce clarity and contrast, ensuring legibility while echoing the chromatic language of the movement.

The Hands

Blued Steel in Motion

The hands are crafted in blued steel, finished with polished, domed and lightly hammered surfaces. Their deep blue tone provides visual precision while maintaining continuity with the coloured elements of the tourbillon.

In-house hand-wound calibre with 5N rose gold finishing

The Movement

A Unified Architecture, Coloured in 5N

The hand-wound calibre is finished in a 5N-toned treatment, extending the material language of the case into the movement itself. This chromatic continuity reinforces the coherence between exterior and mechanism.

Blue-coloured triple-axis tourbillon cages

The Tourbillon

Blue-Coloured Triple-Axis Cages

The Mysterious Triple-Axis Tourbillon features blue-coloured cages, rotating at differentiated speeds. Beyond their visual presence, these coloured components enhance legibility and emphasise the spatial complexity of the regulating organ.
