U-Boat Classico Stratos 40mm

The Classico Stratos reworks U-Boat’s essential Classico design into an unusually slim 9.5mm-thick case, just 40mm in diameter, making it easy to wear under a shirt cuff or a tuxedo sleeve. The AISI 316L stainless steel case keeps the brand’s left-sided crown and polished tungsten bezel ring, while the three-tier black dial with a visible ruby is lit with luminous beige markers. A U-shaped, fumé sapphire caseback window, sealed with seven external screws, offers a glimpse of the hand-wound mechanical movement, which runs at 21,600 vibrations per hour with a 42-hour power reserve. The watch is completed with a hand-finished dark brown alligator leather strap and is rated to 100 metres of water resistance. GTIN: 8051070194160.
