An NH movement and a 28.5mm dial go into the RC1163, our steel Nautilus-style case, brushed on top and polished on the sides. The case cover in the box is brushed silver to match, and the crystal is flat sapphire with clear AR. Add a bracelet to the order if you want the set; either way, your Seiko mod is silver from case to case cover.

Had this plan inspired by the sbbn049 Tuna that got realized thanks to this case and the T1000 bezel, it's absolutely beautifully made.
Everything fits perfectly and the finish is very good.
Combined the Tuna case with the T1000 bezel and it's super nice. This mod wears exceptionally well for the diameter the numbers say it is. Absolutely recommend for anyone considering a Tuna build.
Great case, awesome customer service!
Did a build in this 6105 conversion case and I'm really satisfied with the quality and tolerances.
