Mecanograph

Mecanograph reflects the synergy between an exclusive Louis Moinet chronometer-certified movement and the brand’s incomparable aesthetics.  

Conceived by Louis Moinet and produced by Concepto, Mecanograph’s remarkable Calibre LM31 is on show through both the half-dial on top and display-back underneath, making this timepiece as spectacularly eye-catching as it is technically innovative.

Mecanograph indicates hours and minutes with signature central Gouttes de Rosée hands, as well as small seconds displayed by a Goutte de Rosée hand on a distinctively shaped subdial at 9 o’clock.

While the right half of the dial boasts stylish and emblematic Côte du Jura guilloche, the left half is pure mechanical beauty, with the escapement, screwed balance, lever and gear train of the 182-component, COSC-certified, automatic movement on display along with the anthracite-coated mainplate and bridges.

The display-back offers a fresh perspective on the wonderful movement. The bridges, anthracite-treated and enhanced with 26 jewels and blued steel screws, are adorned with a Côtes du Jura motif, as is the bi-directional winding rotor mounted on a high-tech ceramic ball bearing.

Mecanograph’s case is in either grade 5 titanium or grade 5 titanium and 18k rose gold, and features the Louis Moinet signature six-screw bezel and interchangeable crown tube system.
