The Panerai Radiomir Replica collection, there are two main case styles: the Radiomir and the Radiomir 1940. The overall look of these two may be quite similar at a glance, yet if we look closer we see a handful of distinct differences.
The Radiomir’s case design evolved for even better performance. For improved resistance to tension and to prevent the lugs from detaching from the case under extreme pressure or impact, the Panerai Replica case and lugs were built out of the same block of steel rather than welding lugs onto the case.
The watch was called Radiomir – referencing the patented luminous material from 1916 – and it paved the way for the design blueprint of all future Panerai Radiomir copy watches.
While also 47mm in diameter, the case designs were based upon the evolved vintage Panerai watches with thick lugs and a cylindrical crown.
Both Copy Panerai Radiomir and Radiomir 1940 cases are available in a variety of sizes, typically 42mm, 45mm, and 47mm, although a few other sizes (always 40mm or larger) are sometimes used for special edition models.
