Seiko Reveal Prospex ‘Save The Ocean’ Antarctica 2022 Monster and Baby Tuna

Seiko Prospex 'Save The Ocean' Antarctica 2022 Monster and Baby Tuna

At this point the Seiko Prospex ‘Save The Ocean’ line may as well be its own subcollection. It’s been expanded year on year since around 2018 when Seiko first created a partnership with Fabien Cousteau, grandson of the legendary explorer Jacques-Yves Cousteau (he of red hat fame). Last year saw ‘Save The Ocean’ renditions of the Samurai, Turtle, Monster and Baby Tuna. It’s the latter pair that have returned at the start of 2022 with updated designs for the Prospex ‘Save The Ocean’ Antarctica 2022 collection.

While the overall appearance of both watches is different because, you know, they have completely different cases, the core theming between them is the same. Textured blue dials that evoke images of freezing, iceberg filled water with the imprint of penguins between 6 and 10 o’clock. It draws attention to the fragile ecosystems of Antarctica and the unique life and biodiversity that they support.

Seiko Prospex Antarctica Monster 'Save the Ocean' SRPH75K1

As for the individual watches, the Monster is as big and brash as its namesake, measuring 42.43mm in diameter with a chunky bezel with big notches. While it is large, it’s not egregious for a tool watch and with short lugs that give it the appearance of an integrated bracelet it sits well on wrists that would normally be too small for a watch that size.

Seiko Prospex Baby Tuna ‘Save the Ocean’ SRPH77K1

The Baby Tuna is actually larger at 43.2mm due to its shrouded bezel, despite it being a ‘baby’ version of the even bigger Tuna from 1975. It also has its own distinctive elements that separate it from the Monster, a knurled bezel, smaller date window sans cyclops lens and differently shaped hands and hour markers.

Seiko Prospex 'Save The Ocean' Antarctica 2022

Inside each watch is effectively the same calibre, the 4R35 in the Baby Tuna and 4R36 in the Monster. The difference in reference number reflects the placement of the day/date functions on the two watches as they’re otherwise identical with automatic winding and a 41-hour power reserve.

More than just the calibres are similar between the two models in the Prospex ‘Save The Ocean’ Antarctica 2022 collection, as they are closely matched in price too. £480 for the Tuna and £490 for the Monster, both of which are £30 more accessible than their 2021 counterparts. While it’s not the most exciting new release, as it effectively comes down to an updated dial, anything that puts penguins front and centre is alright by us.
