Diver 300 Heritage

Ships within one to two (1-2) weeks after purchase.

The Seastrong Heritage Automatic captures the golden age of dive watches, pairing Alpina’s mid-century tool watch DNA with modern engineering. Sized for presence but refined in execution, it delivers vintage diver charm with practical specs, dual crowns, and bold dial options.

Housed in a 42mm stainless steel case, each version features an internal rotating bezel controlled by the 2 o’clock crown, protected under a boxed sapphire crystal. The AL-520GR4H6 features a deep sunburst brown dial paired with a green rubber strap for a sport-forward execution. The AL-520BY4H6, by contrast, brings warmth and elegance with its black gilt dial and classic brown leather strap.

Inside both is Alpina’s AL-520 (Base Sellita SW200) automatic movement with a 38-hour power reserve, visible through a sapphire caseback. With 300 meters of water resistance, screw-down crowns, and sharp heritage styling, the Seastrong Heritage Automatic is a true diver with one foot in the past and one planted firmly in the now.
