The new hand-wound movement with a power reserve of three days, which powers the new Radiomir 1940 3 Days.
The new Radiomir 1940 3 Days has the system for stopping the balance which operates in conjunction with the device for zeroing the seconds hand: when the winding crown is pulled out, the balance wheel stops and the seconds hand, rotating in the classic subsidiary dial at 9 o’clock, is moved back to zero, so that the watch can be synchronised exactly with the reference time signal.
The sapphire crystal of the porthole on the back of the new Radiomir 1940 3 Days enables the construction and finish of the P.1000 movement to be admired while the polished bezel frames the classic Panerai black dial, with large bar markers and figures.
The dial has the sandwich structure invented at the end of the 1930s to maximise the visibility and legibility of the markings: two superimposed discs contain the luminous substance which shines through the holes in the upper one.
