Panerai Luminor Submersible 1950 3 Days Power Reserve Automatic Bronzo (Video)

Among Panerai’s Luminor Submersible collection of military-style diving watches, the one that most evokes the brand’s Italian navy origins is the Luminor Submersible 1950 3 Days Power Reserve Automatic Bronzo 47 mm, with its dark, military green dial and bronze case.

Bronze is a material readily associated with sailing, diving, and other nautical pursuits due to its use in vintage yachts and ships. The bronze used in this watch’s case is CuSn8, an alloy of copper and tin in its pure state, which is both structurally strong and highly corrosion-resistant. Over time, the material’s warm tone will develop a patina as it reacts to external agents such as air, humidity, heat and wear, rendering each watch unique to its owner and his or her experiences.

The large case (47 mm in diameter) has the familiar, trademarked Panerai locking-bridge crown protector and is water-resistant to 300 meters. The sapphire exhibition caseback is anchored by a ring of titanium, a material chosen for its non-allergenic properties.

What differentiates this Luminor Submersible model from its predecessors is a new feature on the dark green dial, an arc-shaped power reserve indicator at 4 o’clock. The dial also has luminous, applied hour markers, a date window at 3 o’clock and a small seconds subdial at 9 o’clock. The studded, rotating bronze bezel, with 15-minute scale for timing dives, is designed with a patented system that ensures the ratchet moves precisely from one click to the next.

The watch (which Paneristi will likely refer to by its reference number, PAM00507) is powered by Panerai’s automatic Caliber P.9002, produced at the brand’s manufacture in Neuchâtel, Switzerland. Composed of 237 parts, it has a rotor that swings in both directions to wind two series-connected spring barrels, bestowing upon the Submersible a lengthy three-day power reserve. It also includes a device for zeroing the seconds hand so the wearer can synchronize the watch with a reference time signal.
