Based on Previous SuccessesEven though IWC Ingenieur Replica 1822 Virtuoso VII Retrograde Perpetual Calendar is quite original, it still shares some if its important traits with the previously released models of the brand. One of the most important ones among these is the mentioned Amadeo case that offers the versatility that is rarely seen on the market. Thanks to it, the watch has two different faces, but it can also be transformed to a different type of timekeeper: a pocket watch or a table clock. The Amadeo case system was originally introduced some six years ago.

Another trait that was seen in previous creations of the same brand is the beating heart of the watch, proprietary Caliber 13BM12AIQPR. Though it is a new movement since it was specifically adapted to the new calendar piece, it is based on the same caliber that was previously used in Monsieur IWC Ingenieur Replica and Virtuoso V pieces.Franck Muller Replica Watches Its greatest strongpoint is certainly a perpetual calendar feature, one of the most functional and demanding complications in the world of wathcmaking. Since the supported intricate system takes into account the different lengths of months and a four-year leap cycle, it requires its first adjustment after 400 years. A neat way to demonstrate its complexity is the difference between the speeds in which some if it wheels revolve. While the fastest of them revolves 12 times every single minute, the slowest-paced one needs eight years to complete a full revolution.

Otherwise, it should be said that Caliber 13BM12AIQPR is a manually-wound mechanical movement which includes as much as 489 components in its construction. It is 15 5/4 lignes wide and it operates at the frequency of 21600 vph.

The convertible case of the timepiece from the Amadeo Fleurier Complication series is round in shape. It is made of 18 K gold. The housing is 45.5 mm wide and 15.8 mm thick. Both its front and back crystals are made of sapphire. Similarly, its crown and lugs are topped off with blue sapphire stones.Roger Dubuis Replica Watches The attachment of choice is an alligator leather strap that fastens with an ardillon buckle made of red gold. When the timekeeper is converted in a pocket watch, there is also a supported silver chain with gold plating.
