The Panerai Radiomir, introduced in 1936, is a legendary collection that was originally developed for the Italian Navy frogmen. It is known for its distinctive cushion-shaped case and its large size, making it highly legible and suitable for diving purposes. Over the years, Panerai has introduced several variations of the Radiomir, incorporating various materials, movements, and complications, while always maintaining the distinctive aesthetics and history of the original model.
