The Panerai Luminor Luna Rossa Regatta 47mm is the biggest of the trio, and the substantial case, which measures 19.94mm thick, is resplendent with Panerai’s Carbotech case construction, which involves layering carbon fibre and then bonding the structure with polymers. The end result of this complex case material is that the Luna Rosa Regatta itself is relatively light, although its size is the largest of all replica watches currently on the market. 
Housed within the Luna Rossa Regatta’s distinctive case is Panerai’s Calibre P.9100/R, a self-winding movement that benefits from no less than 328 parts, 37 jewels, two spring barrels, Incabloc anti-shock device, Glucydur balance components, 72 hours of power reserve and 28,800 (4Hz) vibrations per hour.
What’s more, the highly spec’d movement hosts a large number of practical functions aimed at aiding the members of Team Luna Rossa on their storied endeavor to break the America’s Cup record. Finally, in addition to hours, minutes and small seconds, the Luna Rossa Regatta also features a regatta countdown, flyback chronograph and a zero reset seconds.
The Panerai Luminor Luna Rossa Chrono Flyback 44mm differentiate itself from its larger brethren by being finished in a black micro sandblasted ceramic case that measures 18.40mm thick. The obvious benefits of ceramic are two folds, as the material not only gives a near peerless level of scratch resistance, it is also obviously lighter than steel.
The Luna Rossa Chrono Flyback sports Panerai’s Calibre P.9100, which is basically the same movement as that found in the Regatta, sans the regatta countdown complication. As a result, Chrono Flyback still benefits from 72 hours of power reserve, 37 jewels, 302 components, flyback chronograph and zero reset seconds.
Last but surely not least, the Luna Rossa GMT’s case measures 15.65mm thick, making it the slimmest best watch of the trio. The Panerai Luminor Luna Rossa GMT 44mm is hewn from hard-wearing and lightweight titanium, which is then given a Diamond-Like Carbon (DLC) coating to achieve its black aesthetic.
Inside the hardwearing case you’ll see Panerai’s Calibre P.9010/GMT movement, a self-winding workhorse that offers customers 72 hours of power reserve, has 199 components, 31 jewels and, like its siblings, runs at a smooth 28,800 (4Hz) vibrations per hour. The trio is equipped with a “Ponte Vecchio” black calfskin leather strap with contrasting white stitching, all leather straps are decorated with trapezoidal wiredraw titanium buckles and buckles treated with black DLC coating.
