Alpina presents the Seastrong Diver 300 Heritage in a new dark green dial paired with a color coordinated green rubber strap. Measuring 42mm in diameter and water-resistant to 300 meters, the watch’s two-piece stainless steel case mounts two screw-down crowns; one for time setting and winding, the other for rotating the inner rotating rehaute specifically for timing a dive – or any other event up to a one-hour limit.
This retro-inspired design revisits the brand’s Super Compressor 10 Seastrong dive watch, first introduced in 1969. While dive watches have long tended to have neon bright yellows and safety orange dials, Alpina dove head-first into the current trend for green colors with this quite dark seaweed-green dial and British racing green strap. Bold hands are luminous, as are the indices on the inner bezel. 
As with external bezels, diver down times are shown with by Seastrong’s internal black rehaut, which can be adjusted using the upper crown positioned at the two o’clock mark. Unlike most internal bezels, the Seatrong’s can be rotated in either direction before being locked in place by screwing the extra crown down. 
The stainless steel case is polished and brushed on the sides with a solid steel case back engraved with Alpina’s namesake Alps as well as a trident as a nod to the nautical nature of the watch. Inside is the Sellita-based AL 520 automatic winding movement beating at 28,800 with 38 hours of power reserve. Price: $1,695.
The watch is the first Streamliner limited edition H. Moser has created for a partner. Price: $119,000.
Under the hood L’Epee builds a tiered movement with an eight-day power reserve shaped to the bodywork.
