Louis Moinet reveals the brilliance of blue

The brilliance of the colour blue features prominently on Louis Moinet’s Deep Blue 20-Second Tempograph., which is available in a Limited Edition of 60 pieces.

Sometimes, the detail of one mechanism changes the whole feel of a piece: decked in blue, the dynamic and contemporary spirit of Louis Moinet’s 20-Second Tempograph really comes to the fore, “mirroring the spirit of Mr Louis Moinet’s (1768 – 1853) timepieces in his day,” enthuses Jean-Marie Schaller, Louis Moinet’s CEO. “The ethos of our Ateliers is embodied in this 20-Second Tempograph. It’s a thing of extraordinary mechanical beauty: an innovative piece that’s been constantly refined over the years – and its retrograde mechanism is an unending source of fascination.”

The watch is by no means blue all over, though. On the dial, blue has been used, sparingly, just on the time-telling components: the seconds hand at 9 o’clock, the legendary 20-second retrograde mechanism between 1 and 2 o’clock, and the hour dial. On the back, the oscillating weight also offers up its guilloché design to receive this new, deep blue décor, resulting in a scintillating interplay of shapes and hues.
