The latest version of the U-Boat Classico with a tungsten bezel is characterised by a long vertical window - at 9 o'clock on the black dial - displaying today's, yesterday's and tomorrow's date. At 4 o'clock, on the other hand, is the AM and PM indication. Other stylistic details include the beige hue of the SuperLuminova-treated hands and the double bar indices positioned at 4, 8 and 12 o'clock. The satin-brushed 316 AISI steel case, 45 millimetres in diameter, houses the U-28 calibre, a self-winding mechanical movement with customisation to U-Boat specifications, visible from the back through the smoked sapphire crystal cut in the brand's U shape. Guaranteed water-resistant to a pressure of 10 atmospheres, the watch is fitted with a dark brown calfskin leather strap, worked and finished by hand, with a steel pin buckle. Last but not least, the innovative and patented crown release system located at 8 o'clock for easy adjustment of the date and time.
