Panerai Mare Nostrum Titanio (PAM 603) .

It was officially presented in January 2015 at the SIHH (Salon International de la Haute Horlogerie) fine-watchmaking fair in Geneva. This model is a special limited edition of just 150 pieces, featuring an imposing 52 mm satin-finished titanium case and a tobacco-colored dial that closely echoes the design of the celebrated chronograph prototype made by Panerai in 1943 for the deck officers of the Italian Royal Navy. At the heart of the Panerai PAM 603 is the Panerai OP XXV calibre, a high-quality hand-wound chronograph movement developed on the prestigious historical Minerva 13-22 base. It is a column-wheel chronograph, the most refined and traditional technical solution for controlling chronograph functions, ensuring smooth and precise pusher operation. It beats at 18,000 vibrations per hour (2.5 Hz), a low frequency typical of great vintage calibres, lending its ticking an old-world charm. The watch is in like-new condition and comes complete with all its accessories.
