Great Dial

Lovely dial, and the quality is great, fits perfect and the watch looks great with the new Chapter ring as well.

Using this mod part for: SNK803

The details on this dial are absolutely gorgeous and the attention to detail here is second-to-none. These dials are true works of art and I am really excited to have one of them in my latest build. Perfect in every way and the lume is such a fun surprise when the lights go out.

Beautiful dial, brilliant service!

Fell in love with the dial as soon as i saw it, Adriel graciously agreed to assist with the mod work, the output was absolutely gorgeous, i’m thinking i’ll swap out the strap for a darker shade and a more formal look but i can already see this being a regular with my brown brogues. Thank you once again Adriel for your patience with me and my order! :)

Using this mod part for: Vostok 100

I was looking for a wave pattern dial for a playful paddle-in-the-pool theme. This seems to me to be perfect in every way.


Seigaiha Dial (No Date)

Using this mod part for: Turtle

First look... I love it.

Using this mod part for: SNK809
A very beautiful dial!

I made this watch for my wife using a SNK809. The watch turns out better than I thought thanks to the beautiful Seigaiha Dial. It was matched with gold fish bone hands and blue silicone strap.

The next project will be using the Stardust dial. Can't wait.

Once again a unique piece of craftsmanship

Finally I have all the pieces for this mod. It looks so much better than the photos. I just didn't manage to put the intended trident seconds hand but I think the project is completed overall. I just wish the lume on the dial could last a little bit longer like the Kanagawa wave which lasts throughout the night. Overall I would rate it 9.5/10.
