Officine Panerai presents the left-handed version of the Luminor Left-handed - 47mm, in which the winding crown and the device protecting it are at 9 o’ clock, on the left side of the case. Left-handed watches are very much part of the history of Panerai. The commandos of the Italian Navy had to wear several instruments on their wrists at once: not only the watch, indispensable for synchronising their attacks and for keeping track of the length of time spent in the depths of the sea, but also the compass and depth gauge. For convenience, some of them preferred to wear the watch on the right wrist, and for them Panerai created the watch with the winding crown on the left side, as can be seen in some rare contemporary examples which still survive today. The steel case of the Luminor Left-handed - 47mm has a unique detail which distinguishes it from the classic Luminor case: the caseband has a cusped shape, hinting at the form of a cushion case. This little detail, picked up directly from some examples of the period, tells the story which brought about the transformation from the Radiomir, created in 1936, with a classic cushion case, to the Luminor, more massive in its proportions and identified by the device protecting the winding crown.
