ALPINA WATCHES

SEASTRONG DIVER GYRE

The Seastrong Gyre is the latest dive watch from Alpina, but there's a deeper connection to the ocean than 300m of water resistance and an array of ocean-hued dials.

The case is made from a composite that's formed by recycled plastic from fishing nets found in the Indian ocean, and the paired NATO strap is made from recycled bottles. Inside the case, there's an AL-525 movement, based on Sellita's workhorse, the SW-200.

The entire range consists of five models, and 1,883 examples of each will be made. There are two models sized at 36mm in diameter, and three models sized at 44mm to cover a variety of wrist sizes.

The watch is produced in conjunction with Gyre, a startup created by veteran watch writer Bernard Werk that specializes in turning ocean plastic into watches.
