The Piaget Gouverneur Moon Phase Tourbillon is not actually a new design, but a new version of the watch was introduced to the market in February of 2012. The original design first came onto the market in the 1990s. One of the most interesting features of the new design is that it has the thinnest shaped tourbillon that was ever created by any watchmaker. The case of the new is a circular 43 mm. The bezel is oval-shaped. The dial, center, and tourbillon are all circular shaped, along with the indicator for the phases of the moon. A”P” to signify Piaget is stamped into the design which rotates. The tourbillon is designed to be only 2.8 mm in thickness.
The total weight of the Piaget Gouverneur Moon Phase Tourbillon is 0.2 grams. The tourbillon rotates once each minute, so it works as a second hand. The dial of the watch is designed in silver and features a motif of sunburst guilloche. The dial is decorated with pink gold circles in 18 karat gold. The markers for the hour are also detailed in pink gold. The tourbillon is open in a matching frame. One of the most interesting and unique features of this luxury watch is that the moon phase indicator is designed to only need a correction for one day every 122 years.
The moon phase indicator of the Piaget Gouverneur Moon Phase Tourbillon is created in a small size, but is remarkably clear. The moon phase indicator is designed in the same pink gold. The flying tourbillon is created entirely by hand. It features a beveled and hand-drawn carriage. The bridges are designed in a titanium material with a circular-style grain. The finish of the watch is a Cotes de Geneve style, which is created in a circular design.
One of the special features of the Piaget Gouverneur Moon Phase Tourbillon is that the entire movement of the watch is a mere 4.5 mm in thickness. The watch is hand-wound and has a power reserve of 40 hours. The watch beats at an amazing 21,600 vibrations each hour of the day. Another interesting part of this unique design is that the caseback has a crystal window in sapphire which lets the wearer see the entire movement of the watch to admire how precisely it works. The case of this designer watch is available in 18 karat pink gold as well as an 18 karat white gold style.
