Perfect for divers, this Alpina watch is a reinterpretation of its famous Seastrong Diver 300 Heritage Automatic. Water-resistant to 300 metres, this 42 mm design with steel case 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. As with any authentic diver's watch, the two push-buttons are screwed in. The Seastrong Diver 300 Heritage Automatic's engraved case back also reaffirms its nautical vocation. As an update this vintage look, Alpina has equipped its creation with the AL-520 movement, a modern automatic caliber with 38 hours power reserve. Similarly, the traditional hesalite glass has been replaced with an anti-scratch sapphire glass, meaning that the Seastrong Diver 300 Heritage Automatic is now as at home in the sea as it is in the urban jungle. To this end, the Alpina timepiece also comes with two straps, one in brown calfskin leather and the other in beige topstitched rubber.
