To 399 είναι κάσα 1950 με κόρώνα Radiomir?
RADIOMIR 1940 - 47 MM (steel)
A new chapter in the history of the most famous watch designed for underwater military operations
lives again in the new Radiomir 1940, two new Special Edition watches which are presented for
the first time in a special Panerai case of vintage inspiration.
Unlike the prototype and the examples which went into production at the end of the 1930s, some
historic Radiomirs made in the 1940s had a distinctive case in which the strap attachments were
not made of steel wires welded to the case but were formed out of the same block of steel as
the case itself, thus resulting in stronger, more solid lugs. The new Radiomir 1940 watches are
offered in this special case in the classic size of 47mm in diameter, and they incorporate other
elements inspired by the historic examples: the Plexiglas® crystal protecting the dial, the round,
cambered bezel, the cylindrical crown and the screw back.
