Built for eternity

Since the 1930s, the OFFICINE PANERAI brand has specialised in the development of diving watches. As the first manufacturer, PANERAI presented a 200m watertight diving watch for the Italian navy even before WW2. Even back then, the easy to read luminous dials were a decisive advantage, which was protected as a military secret in the years before the war. Today, the strong lighting power of the dial pleases the observer in particularly low light conditions.


Compatible with the dial, PANERAI is delivering the Radiomir 1940 3 Days GMT Automatic Acciaio with a dark brown calfskin strap and beige seams with the name “Assolutamente”. This wonderful combination of the case made of polished steel, the black dial and the dark brown leather strap turn PAM 657 into a timeless classic. The best thing about this version is that OFFICINE PANERAI was able to unify all really important function in the flat clockwork in this timepiece.

Extremely comfortable

An important criterion for all PANERAI models are the best materials and functionality. In the Radiomir 1940 presented here, a 45mm case surrounds a perfect clockwork. The P.4001 calibre with a height of just 5.04mm is very flat. The case is based on a further development of the Radiomir 1936. In this version, PAN 657 is guaranteed to be watertight up to a depth of 100m. The fixed band attachments are studded. In doing so, the band on the watch can be replaced quickly and easily.
