The Panerai Radiomir Black Seal 3 Days Acciaio PAM00388 is the definitive entry point into the Radiomir family — a 45mm black PVD-coated steel watch with the in-house Calibre P.9000 automatic movement and three days of power reserve. Clean, powerful, and quintessentially Panerai.
Overview: What Is the PAM388?
The PAM00388 is part of Panerai’s Radiomir Black Seal line — watches that combine the classic Radiomir wire-lug case with the “Black Seal” designation, a reference to the Italian Navy’s combat frogmen (Gamma Group) who originally wore Panerai watches. The black PVD coating gives the 45mm case an imposing, stealthy appearance that aligns perfectly with Panerai’s military heritage.
Case: 45mm Black PVD Steel
The Radiomir Black Seal uses the classic Radiomir cushion case with its distinctive soldered wire lugs — a construction directly inherited from the original 1930s military watches. There is no crown guard (that is the Luminor’s signature), giving the watch a cleaner, more symmetrical profile. The black PVD coating is matte rather than glossy, which suits the utilitarian aesthetic perfectly.

The Sandwich Dial
The PAM388 features Panerai’s signature “sandwich” dial construction — two layers with the upper layer perforated to reveal the Super-LumiNova beneath. The result is extraordinary legibility in darkness: the numerals and indices glow with a deep, even luminosity that continues to be functional hours after being charged in light. The black dial with black PVD case creates a monochromatic look that is genuinely striking.
Calibre P.9000: Panerai’s Flagship Automatic
The P.9000 was Panerai’s first fully in-house automatic movement, developed at their Neuchâtel manufacture. Key features:
- 72-hour power reserve from twin barrels
- 28,800 vph (4Hz) beat rate
- Automatic winding via bidirectional rotor
- Hours, minutes, small seconds at 9 o’clock
- Date display at 3 o’clock
- Hacking seconds for precise time setting
On the Wrist
At 45mm, the PAM388 is a large watch — but Panerai’s cushion cases wear smaller than their diameter suggests. The lug-to-lug measurement is moderate, and the thickness is well-controlled at around 15mm. On a larger wrist (17cm+), this watch sits magnificently. On a smaller wrist, it may overwhelm — but that is part of the Panerai proposition. These are unambiguous, unapologetic watches.
Verdict
The PAM00388 is one of the best-value Panerai references available pre-owned. The in-house P.9000 movement, signature sandwich dial, and black PVD case make it a definitive expression of the Radiomir aesthetic. Pre-owned examples trade for $4,500–$6,500 — excellent value for an in-house Swiss automatic of this quality and pedigree.
