Panerai Luminor PAM01678 44 mm Blue Dial

The PAM01678 combines a blue matte dial with a 44mm bronze tonneau case, Arabic markers and a leather strap. Super-LumiNova supports the luminous display, while sapphire crystal and a see-through caseback expose the contrast between the watch's warm exterior and its mechanical interior. A fixed bezel, screw-down crown and 500-metre water resistance give this composition a serious saturation-diving specification.

The automatic P.980 is an in-house calibre with a full central rotor, one barrel and 72 hours of power reserve. It has 177 parts and 23 jewels, measures 28.2mm across and 4.2mm high, and beats at 28,800 vph. Hacking seconds and adjustment in six positions add precision to a compact movement whose small-seconds and date displays keep the dial informative.
