The Radiomir was originally created for the Italian Navy. When Panerai needed to meet the increasing military demands of 1940, their designers set to work on designing a new and improved case for their Radiomir watches. The Radiomir 1940 is a perfect example of what they achieved. The cushion-shaped 45mm brushed titanium case is accentuated by the brown face and dials and indicators of a brighter hue. The leather strap adds to the overall look of the watch.
