The Radiomir PAM00643 (aka: PAM643, PAM 643), seen from the bench
The Panerai Radiomir PAM00643 is a 45mm black ceramic case watch embodying military instrumental design principles from the 1930s. It features the manual-wind Panerai OP X calibre, a cream sandwich dial, and a threaded onion crown. The case combines ceramic and stainless steel, achieving both lightness and structural rigidity, while the fixed ceramic bezel resists scratching. Water-resistant to 300 metres, this model represents the Radiomir collection's "basic and essential" philosophy without superfluous decoration. The watch lug width is exactly 27mm.
