Decades before it became a watchmaker, Panerai began making underwater tools for the Italian Navy in the 1910s, registering a patent for its self-illuminating “Radiomir” material in 1916.
Panerai still maintains a relationship with Italy’s Marina Militare, though it’s not the official supplier of critical military tools it once was. Still, that original spirit of innovation lives on today at the brand, as evidenced by the crazy amount of tech packed into Panerai’s latest dive watch, the Submersible GMT PAM01495.

How polarizing
Panerai’s style and tricky history have long made it a polarizing brand, but in this watch, the Italian-Swiss watchmaker is leaning into another type of polarization.
The PAM01495 is powered by Panerai’s in-house Calibre P.4001/S movement. First unveiled in 2021, the skeletonized P.4001/S is one of the brand’s most impressive calibres, and arguably one of the most advanced GMT movements you’ll find anywhere.
It boasts a 12-hour GMT complication with an AM/PM indicator, a jumping local hour hand powered by a patented GMT spring, a seconds hand that resets to zero when pulling out the crown, an offset microrotor to keep things thin ‘n’ pretty, and two mainsprings providing three full days of power, tracked by an indicator on the fully exposed rear side of the movement.
