Launched in 2019, the Seiko x Prospex Diver’s wristwatch made to commemorate the 40th Anniversary of acclaimed Japanese anime Mobile Gundam Suits. Regarded as a global icon since its introduction in 1979, the Gundam series continues to be a major success generating over US$ 600 million in 2018.

To commemorate the important anniversary, Seiko launched a series of limited edition timepieces via the high performance Prospex diver’s watch. With three watches launched, each themed to represent the main robots in the anime, the three watches consists of a Spring Drive GMT as well as a pair of “Tuna” dive watches. With exceptional performance, Seiko’s innovative “Tuna” dive watches earned its nickname due to its peculiar and oversized case construction. Bulky and packed with a punch, the dive watch has an impressive depth rating of 1,000 meters without the need of a Helium gas escape valve. Impressively, the Seiko “Tuna” bears over 20 patents, including an innovative titanium outer case (give the watch a “Tuna can” appearance), as well as the L-shaped single-crystal gasket (which defeats the purpose of a helium gas escape valve).
