To pay tribute to its historical collection Alpina has launched since 2016 the “Seastrong Diver Heritage". Water-resistant to 300 metres, this new 42 mm design with steel case has no room for novelty or unnecessary complications, but the moving inner flange lets you measure your immersion time in hours, minutes and seconds. Practical and timeless, its black lacquered sunray-brushed dial features gold plated luminescent hands, creating the contrast required to make it easy to read, even in the low light of the deep sea.
