- The 2022 edition of the Seastrong Diver 300 Heritage embodies everything Alpina stands for: an athletic feel powered by state-of-the-art technology and vintage undertones in step with its heritage, inspired by the 10 Seastrong, the brand’s very first Super Compressor. This new watch stars something of a first for the Maison, too: a green face paired with an original green rubber strap. Thanks to its two push-buttons – one to set the time, the other to programme its mobile rehaut – the latest addition to the family stands out as the ultimate automatic dive watch, measuring 42 mm across and water-resistant up to 300 metres.
