A dark night on the Mediterranean Sea. The Italian commando diver kicks smoothly through the depths, hidden in the gloom \u2014 black wetsuit, black goggles, black face paint. On his wrist, a giant blacked-out-steel dive watch, the lume glowing brightly in the dark night. This is the Panerai most watch enthusiasts know and love. But while the storied Italian brand did make watches for the Italian military in the 20th century, modern Panerai stands for so much more. There\u2019s the action hero kind of Panerai \u2014 like the Luminor, which has appeared on multiple muscled celebs over the last decades. The dress-watch kind of Panerai \u2014 a black-on-white sandwich dial that\u2019s a tuxedo\u2019s best friend. The tool watch Panerai \u2014 a hulking yet beautiful piece of steel that can withstand corrosion, UV rays, and pretty much anything else mother nature throws at it. And now, Paneristi, as fans are called, have another Panerai launch to soak up. The new Panerai Submersible QuarantaQuattro, an instant classic in 44mm that seems destined to reach well beyond the diver crowd to an even wider group of active individuals. This is the new Panerai, blending military tool watch, luxury-level finishing, beautiful aesthetics, and everyday wearability. Not just for a dive watch enthusiast \u2014 for a do-it-all adventurer who wants a watch capable of everything and ready for anything. The Submersible line of Panerai timepieces are made up of survival instruments first and foremost: a unidirectional bezel, oversized crown guard, and 300m of water resistance means they will easily handle any dive, hike, ride, or surf session. The new QuarantaQuattro thrives because of its size. At 44mm, this new version hits the \u201csweet spot\u201d for many collectors. It\u2019s 2mm bigger than the smallest 42mm version, lending it that this-is-a-Panerai heft; but dropping 3mm from its larger 47mm cousin means you don\u2019t have to have arms like Stallone to rock it well. The resulting watch, with its (new and improved) date window at 3 o\u2019clock and small seconds subdial at 9 o\u2019clock, is pristine and perfectly sized for adventure: SCUBA in the morning, exploring town at midday, and black-tie cocktails at night. Its P.900 caliber automatic movement has a three-day power reserve (though this summer we doubt you\u2019ll take it off that long). Its rubber and fabric straps are made using upcycled materials, to the benefit of the planet. Both white and black dial options with stainless steel case and bezel are perfectly suited to such pursuits \u2014 as is our personal favorite, the Carbotech case with blue dial. This new carbon-fiber-based material is lighter than titanium and scratch- and corrosion-resistant. Its bezel is DLC-coated titanium. Any of the three is just the right watch for your next adventure \u2014 whether that be a nighttime dip in the Mediterranean, trimming sails in the Caribbean, or just nabbing a cocktail in the harbor bar.
