n iconic design from the Lucca-based maison is reinterpreted in its chronograph version, featuring a titanium case, tungsten bezel, and a new “waffle” patterned dial available in three shades with an extraordinary hypnotic effect.

Titanium, a robust metal known for its high strength and exceptional lightness, is used in its Grade 2 version, combined with the indestructibility of tungsten to breathe new life into the timeless, clean lines of the watch designs by Italo Fontana.

Three versions with a 45 mm case feature a high-quality sapphire crystal protecting a three-level dial. The top layer showcases an attractive waffle pattern in black, grey, or blue, framed by a matte tungsten bezel that makes the watch virtually scratch-proof.

Indestructibility and lightness harmonise with the matte finish of the case and bezel, giving the new chronographs a certain sobriety and classicism, elevated by the elegance and originality of the new patterned dials.

The intriguing dial motif is interrupted by three sub-dials for the chronograph function, plus an additional 24-hour counter with a red hand. These counters are designed in contrasting colours: black for the grey and blue versions, and grey for the black-dial version.

Produced in limited, numbered editions of just 299 pieces per colour, the signature oversized crown of all U-Boat watches is positioned on the left side of the case. It features a trademark large crown cover secured to the case with a protective latch.

Accompanying this is a patented discreet pusher for easy crown extraction (located at 8:30) and two additional pushers for chronograph activation and reset, positioned at 8:00 and 10:00 respectively.

The case back, precision-sealed with seven screws, ensures water resistance up to 100 meters and offers a captivating view of the Swiss Sellita SW500 movement and its personalised rotor through a sapphire crystal window laser-cut in the shape of a U.

Completing the range of new chronographs is a strap with a titanium buckle, crafted in Alcantara rubber with a leather lining. With the three new Classico Chrono 45mm models, U-Boat reaffirms the Classico model’s status as a leading chronograph watch and an enduring icon of elegance and timeless design.
