This year, the Tonda Métropolitaine Sélène is making a reappearance as a special edition featuring a new colour scheme.

THE LUNAR DANCE ACROSS THE DIAL

With its two bronze-coloured lunar discs, which appear and disappear behind the wisps of a cloud, the Tonda Métropolitaine Sélène has the hallmarks of a conventional moon phase model. Despite this classic appearance, this timepiece features numerous distinctive touches executed thanks to the expertise of the Parmigiani Fleurier Watchmaking Centre, making it a true original.

Its russet-coloured moon radiates the magical glow only witnessed on exceptional nights. It is magnified thanks to its surface made up of craters — known as lunar seas — obtained by applying successive layers of transfers, a complex process which involves great skill. Much more than a simple representation, this is a genuine embodiment of the moon on the wrist.

A MOTHER-OF-PEARL LOTUS FLOWER

The aesthetic power of the piece resides in the lotus flower adorning the centre of the dial, which emphasises the inherent femininity of the complication. This flower, which blooms at night, just as the moon appears, also symbolises the female gait. It is said in certain cultures that every step a woman takes produces a lotus flower.

It is created using mother-of-pearl lace designs measuring barely 0.2 mm thick, applied in two layers. The first underlying sheet is varnished then satin-finished, providing a contrast with the upper polished layer. The alternating satin-finished and polished surfaces produce a captivating reflection, which is further enhanced by the inherent depth effects of the two mother-of-pearl layers.

In 2017, two dial colours – a pastel pink and a subtle sky blue – will be added to the existing versions in Abyss blue and white. The colours of these two special editions are obtained by applying a varnish to the back of the underlying mother-of-pearl sheet, which suffuses through to the surface, enhancing the reflections generated by the material. The bezel, which is set with 72 brilliant cut diamonds, and a "pearly white" leather strap, enhance the rich, lustrous texture to envelop the wrist. The indices, in 18 carat solid gold, stand out elegantly from the dial.

The richness of the Tonda Métropolitaine Sélène resides in each of its individual details and its overall integrity. Operations carried out by hand, never substituted, give it a perceptible and unique value.

THE MOON PHASE COMPLICATION

The PF318 movement and its moon phase module were entirely manufactured in the Parmigiani Fleurier workshops. The moon phase operating principle is based on a gear moved by the hour wheel, which rotates at half the speed of the gear. This means that the gear drives the moon disc every 24 hours via a flexible blade integrated in the centre of its wheel.

A corrector at 9 o'clock enables the wearer to independently index the moon in relation to the day and date in order to match its phase to the geographic reference location. This moon correction device features a safety system thanks to the blade, which is flexible to prevent irreparable damage to the gear in the event of incorrect operation.

The PF318 self-winding movement has a power reserve of 50 hours and excellent isochronism thanks to its two series-mounted barrels that regulate the power reserve. Visible through the watch's transparent case back, this calibre is entirely circular-grained, decorated with Côtes de Genève and bevelled to the finest haute horlogerie standards customarily applied in the Parmigiani Fleurier manufacture.
