The black dial is constructed in Panerai’s famous “sandwich” style, and has large linear hour markers and numerals. The chronograph hands — orange for minutes, blue for seconds, and a smaller orange hours hand in the subdial at 3 o’clock — are designed to be easily distinguishable from the central, white hours and minutes hands. The small seconds run continuously in a subdial at 9 o’clock. The flange around the dial displays a 15-minute scale for the regatta countdown, with the five final minutes distinguished in orange, along with a tachymeter scale that is measured in knots, which enables a sailor to determine the speed of his boat over a defined distance.
The large Luminor case, 47 mm in diameter and made of light-but-strong, hypo-allergenic brushed titanium, includes Panerai’s familiar lever device for protecting the winding crown. The bezel has a contrasting brushed finish. The caseback has a wide sapphire crystal window that offers a view of Caliber P.9100/R.
The new movement is identical to the base caliber P.9100 in architecture and diameter (13 3/4 lignes) but is a bit thicker than its predecessor (9.55 mm) and has more parts (328 total), both owing to the addition of the regatta countdown function. The bi-directional rotor winds the springs of the two barrels, providing the watch its three-day power reserve. The chronograph functions, along with the device that controls the backward-moving minute hand for counting down, are all controlled by a column wheel. The variable inertia balance oscillates at 28,800 vph.
As one would expect from a timepiece meant to be used as a professional sailing instrument, the watch is highly water-resistant, to 100 meters. It comes on a sporty rubber strap with a brushed titanium buckle, along with a replacement strap that can be changed using the provided tool in a system patented by Panerai. The Luminor 1950 Regatta 3 Days Chrono Flyback Titanio is priced at $18,800.
