Radiomir 1940 Oro Rosso

"The P.999 is a mechanical movement combining reliability, robustness and precision and featuring the special structure with wide separated bridges that characterizes all the other Officine Panerai Manufacture calibres. With a 12 ligne diameter, equal to 27.4 mm, and a thickness of 3.4 mm, the P.999 calibre is slightly smaller than the other Officine Panerai calibres making it ideal for models which are smaller, both in diameter and in thickness, than the historical watches. With 19 jewels, a single barrel providing a 60-hour power reserve and small seconds at 9 o’clock, the calibre is made up of 154 components and beats time at a frequency of 3 Hz: this means that its balance wheel makes 21,600 alternations/hour. Equipped with adjusting screws, the balance wheel is protected by an Incabloc® anti-shock device while the regulating system of the flat spiral is of swan’s neck type in the pink and red gold version of the movement."
