Updating their classic dive watches in time for Baselworld 2016, Alpina created the Seastrong collection, which all share a vintage-inspired look. The 44mm stainless steel cushion-shaped case is available with a grey, navy blue, or burgundy uni-directional diving bezel with white luminous markers displayed on a rubber nubuck strap. The black dial is simple and uncluttered, featuring a discreet single date window at 3 o’clock and white luminous hours and minute hands for optimal legibility. The AL-525 automatic calibre movement operates at 28,800 vph to a depth of 300 metres, with 42 hours of power reserve. Plenty of time before you need to resurface.
