The green Seamaster is often nicknamed the “Seaweed”, a colorway that has quickly become one of the most desirable modern Seamaster variants among collectors.

Fun fact: The laser-engraved wave dial was reintroduced in 2018 as a tribute to the original 1990s Seamaster worn by James Bond, bringing the iconic pattern back with modern ceramic technology.
