Aptly named for its resemblance to a can of tuna, the NMK920 Tuna SKX007/SRPD Watch Case Bundle: Black 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.

Such a gorgeous Tuna conversion case. Will purchase more for future builds. Still waiting on my "Nemo" bezel insert from ebay. That would be a cool offering. Love me some orange and blue.
this tuna case is really well build and a good quality one
Great case, wish I would have known to use a flat bezel insert off the bat though, a sloped insert leaves an unsightly lip.
I looked at other options but the big thing that I noticed on an original tuna and this case is how seamless the shroud fits with the case on the underside. There are no gaps between the case and the shroud. I had to watch a lot of videos and look at pics of other tuna conversion cases to see that all the others are just a shroud on a basic case. The gaps underneath can be unsightly and I would think uncomfortable. The Namoki tuna case looks amazing! It’s a heavy piece but well built. I was concerned that I couldn’t chose my own crown and bezel but the combo is really beautiful. Looking forward to an awesome build!
