Alpina launches the Seastrong Diver 300 Automatic Calanda, its first timepiece made with a 100% recycled stainless steel case. The watch, named to pay tribute to the Calanda, the first ship to fly the Swiss flag, uses recycled steel sourced from the shipping industry and made by Thyssen Krupp. Alpina pairs the watch’s 42mm case with a recycled plastic wristband.
The Geneva-based watchmaker adds the new dive watch to its expanding lines of eco-friendly models. You might recall that Alpina also launched the Seastrong Diver Gyre Automatic collection in 2020. That watch features a case made largely (70%) from plastic fishing net debris. In addition, that model’s strap is made using recycled plastic bottles while its box is made from recycled plastic.
Available as a limited edition of 300 units, the Seastrong Diver 300 Automatic Calanda’s case is polished with a satin finish, while its unidirectional rotating notched bezel is brush-finished. Alpina embeds the hour and minute hands with vintage beige luminescence and tips the seconds hand with a red triangle Alpina logo.
Alpina sets the watch’s matte black dial with appliqué indexes that have also been brushed with the vintage beige luminescence. Fit with an AL-525 Sellita-based automatic movement, the watch is water-resistant to 300 meters thanks to its full screw-in case back and crown. Alpina embellishes the caseback with mountain peaks placed under a trident in a nod to the watch’s seaworthiness.
As noted above, Alpina has paired the watch’s recycled case with a recycled plastic (PET) strap in grey and black. Each watch comes in a case entirely made from recycled plastic, alongside a single-page warranty and a certificate of authenticity printed on FSC Recycled-certified paper.
