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

NMK 920 Tuna - Blue Steel Finish

I ordered this unique style and finish and it has a vintage feel. I paired it with the white wave dial, domed sapphire crystal, and blue rubber strap. The dial is at the 4 o’clock position. It was really a great build and one of my jewels in my collection. Namoki Mods has so many offerings and styles in different modding parts that it’s sometimes hard to chose. They have been helpful when I send my order in to make sure the parts are compatible.

Great product for a great price

As described, this case fits well with skx components for the bespoke look I was looking for.

Tuna case

Awesome case! Second one I have bought. I swapped the black shroud onto the stainless one for a more OEM look! And I love it.

Seiko stealth ‘tuna’ case

What a fantastic case, big and tooly but very wearable!

The finish and construction is fantastic, bezel action is great too, very Seiko like.

My only criticism is the space between the lugs is limited and fitting thicker rubber straps was difficult, only recommendation would be to extend the lugs slightly or remove some steel from the case to create a touch more room.
