The Royal Italian Navy knows a thing or two about the need for a dive watch — which is why they turned to Italian watchmaker Panerai on the eve of World War II to outfit them with a durable diver to withstand the rigors of use by armed services.
This partnership started with the Radiomir and eventually yielded the Panerai Luminor 1950, a timepiece that has helped cast the foundation for Panerai while also becoming highly-adored throughout the watch world and beyond for its unique look.

The Luminor 1950 utilized many of the Radiomir’s details that were built for long durations underwater: a 47mm cushion-shaped steel case, luminescent numerals and indices, lugs made from the same block of steel as the case and the use of overlapping plates for the dial (known as sandwich construction).
