DELIGHTFUL DERIVATIVE


The revolutionary Panerai P.2005 watch movement set a standard for diving watches, thanks to world-reknowned accuracy, a GMT function, manual winding and three spring barrels that accumulates enough energy to operate the watch for at least six days.

One delightful derivative of this calibre (the movement of the watch) is the Luminor 1950 Tourbillon GMT 47 MM Titanium. This watch combines tradition, sports qualities and exclusivity, along with durability characterized by a strong yet light case created in Grade Two titanium.

The new Luminor is distinguished in particular by the tourbillon, a device invented by horologist Abraham-Louis Breguet at the end of the 18th century in order to eliminate errors of rate (faster or slower variations in time indication) caused by changes in the center of gravity, inaccurate workmanship, the thickening of the lubricating oil and the consequent varying friction in the different positions assumed by the watch. Luminor 1950 tourbillon gmt 47 mm titanium (Pam306)To do this, Breguet made a cage containing the balance, escapement and related pivots which rotated continuously on its own axis. In this way the deviation which was found when the balance was in a particular position was cancelled out once the balance was in the opposite position. For more than two centuries synonymous with great difficulty of construction and in recent years adopted only in wristwatch models of the highest quality, the tourbillon has fascinated generations of enthusiasts and constitutes an important challenge for many engineers.

The challenge to Panerai was to create a watch incorporating tourbillon technology, yet present the Italian company’s own unique take on the French timepiece feature. In traditional tourbillons the cage with the balance rotates on a plane perpendicular to that of the base of the movement and it usually makes one complete rotation each minute. In this Luminor, however, the cage rotates on an axis parallel to the base of the movement. Furthermore, it makes two revolutions per minute and this (combined with the particular arrangement of the cage itself) makes Panerai’s take on the innovation better adapted to compensate for running errors due to position, which in a wristwatch are very much more numerous than those found in a pocket watch.
