Rejoice for those who like it small, the first ever Seikonaut @ 36mm! Including the side notches and crown, it goes up to 40.5mm and 43mm, respectively. Thus, giving this 36mm case a 40mm presence on wrist. Small, yet a huge statement.

Additionally, you will get an extremely crystal clear view of the dial and hands you would think there was no crystal in place. This was achieved by having both the outer surface and inner surface of the sapphire crystal coated with clear anti-reflective coating, also known as double sided AR coating. A simple procedure that brings new joy to visually appreciating your own mods.

Together with an integrated bracelet designed specially for this case.

**Designed to fit all of our dials (28.5mm) and original NH movements (grey dial holding spacer). Not suitable for GMT NH34 movement.

My Tiffany Seikonaut 36mm

Stunning case and bracelet, great quality. Amazing super-fast shipping and delivery is outstanding. It looks so classy. It looks better in person. I cannot thank Lucius enough, thank you for precutting the stem to fit my Seiko NH movement. This is my favorite watch mod from all my previous ones. Perfect size, the 36mm wears like a 40mm. Thank you. Jorge from CT, USA.

First Build - Amazing Case and Bracelet!

This is such a well-built product. It looks and feels like a high-end luxury piece. I recommend getting the solid case back to shave an extra 0.6 mm off the profile for a perfect fit on the wrist.
