Panerai Luminor PAM03312 44 mm Diamond Dial

The PAM03312 presents the Luminor in a 44mm stainless-steel tonneau case, with a black dial, Arabic markers and a small-seconds display. Alligator leather brings a dressed texture to the strap, while sapphire crystal and a see-through caseback keep the construction visually open. The fixed steel bezel, screw-down crown and 500-metre rating make its technical purpose impossible to mistake.

Power comes from the in-house automatic P.980, whose full central rotor winds one barrel for a 72-hour reserve. The 177-part movement has 23 jewels, a 28.2mm diameter and a 4.2mm height, with a frequency of 28,800 vph. Hacking seconds and six-position adjustment sharpen the setting and regulation story; the calibre also provides a date alongside hours, minutes and small seconds.
