In some models the solid and closed case-back is replaced by one with a transparent centre made of plexiglass, allowing the mechanism to be seen. The power reserve thus became a fundamental element in the DNA of the Florentine brand. In roughly 80 units, a Swiss-made Angelus SF240 mechanical calibre was adopted for the first time, with an 8-day power reserve. The crown-protection bridge is inserted and adapted to the middle case of the Ref. The luminescence now comes from a new low-radiation tritium-based compound which takes the name Luminor. In the process of assembling the overlapping disc dials, known as sandwich dials, the use of radium-based paste disappeared, and with it the name Radiomir.

6152/1 watch continued unabated in the 1960s. To improve the legibility of the dial, its layout was redesigned with just 4 large Arabic numerals in the cardinal points and 8 indexes at the hour markers.

To improve its function, Giuseppe Panerai modified the structure of the dial with the use of overlapping discs, known as sandwich dials, and the upper part in anodized aluminium with perforated indexes and numbers in order to make the radium paste more legible and luminescent. With this decision, regular supplies of Panerai watches to the Regia Marina took place.

Today's Radiomir watch retains many of the features of the Ref.3646: a large cushion-shaped steel case with a diameter of 47 mm, luminescent numerals and indexes, wire lugs welded to the case and a high-quality manual mechanical movement (at the time, a Cortebert/Rolex 618 calibre derived from a pocket watch was used) and a tanned, water-resistant leather strap, (long enough to be worn over protective clothing). This was followed by the creation of the Ref.3646, the instrument that we know today as the 'Radiomir' watch.
