Longines HydroConquest GMT
Diving watches are often purpose-built affairs, designed for monitoring the time underwater and not much else. The new HydroConquest GMT from Longines is an exception, packing a travel-friendly GMT feature into a timepiece with a 300-meter water resistance rating. It's powered by an ETA-based caliber L844.5 automatic movement with an independently-adjustable local 12-hour hand and a date window at 3 o'clock. The 41mm stainless steel case is consistent across all the variations, which include four sunray dial options. Blue and black dials get silver indices and hands, with rubber strap options in addition to steel bracelets, while the green and brown dials have gilded indices/hands and are optionally set on NATO-style straps.
