Aptly named for its resemblance to a can of tuna, the NMK920 Tuna SKX007/SRPD Watch Case: Brushed Finish is our take on one of the most original and iconic (some would say extreme) dive watch designs released by Seiko. Now you can cook up your own Tuna in any style you like.
Not just a pretty face, the Tuna was (and still is!) an engineering marvel designed to solve issues professional divers faced at extreme depths, producing many industry firsts – it’s iconic shroud, vented straps and L-gaskets just being a few. If you want to learn more about about the history, design and legacy of the Tuna, we did an excellent Dive Deep article that you can find here.
