Watch collaborations tied to sporting events can get pretty predictable. Change a dial color, engrave something on the caseback, make a few hundred pieces… boom. Alpina seems to have gone further with its new Seastrong Extreme Automatic x Route du Rhum Destination Guadeloupe. Created around the 13th edition of the solo transatlantic Route du Rhum sailing race, the new Seastrong is limited to 313 pieces and uses Alpina’s compact Extreme case. It measures 39mm across, 40.5mm lug-to-lug, and 13.4mm thick, with 300 meters of water resistance and a sapphire crystal.
