I previously built a Rotate Watches kit but wanted to build something where I wasn’t constrained by kits. It would let me chase the look I wanted and ensure that I had figured out how sizing and part compatibility works.

Seagull St3600 movement (about to be replaced with a genuine ETA 6497), sapphire crystals front and back.

I’m currently designing my own case and dial in CAD and am planning on trying to mill my own parts as my next step.

Let me know what you think!

    I’m surprised you’re not tempted to have a logo or maker name on the face, like a potatoe, written in potato resolution.

    This is amazing! I Love the open back case.Thanks for posting!

      Thanks! I’ll be honest, when I got the case I found myself questioning why I wanted to try and make my own - I really like it…

        I want to try it too. My question is how did you get the measurements, the fiting of the case with the movement, and secondly did you make the dial? Or you bought?

          I started by selecting the movement that I wanted to use - the ETA 6497. I then looked up the movement dimensions. This movement is 36.6mm.

          I then looked for cases designed to fit a 6497. This is a pretty large movement (originally meant for pocket watches) and I wanted the smallest case possible. I eventually landed on a 42mm case from SK-watchparts.

          Different cases require different dial diameters. This one needs something the same size as the movement or very slightly larger. I went looking for something between 36.6 and 37mm. It needs to be designed for the specific movement so that the dial feet are in the correct location.

          Similarly, I looked up the dimensions nedded for the hands. The case opening is 34mm so I went with a 17mm minute hand so that it barely clears. A 15mm hand would probably look better tbh. The hands have different mounting diameters so I made sure to get ones that were listed as fitting my movement.

          I’m planning on trying to make my own dial next - I want to use a piece of reclaimed wood with a markings engraved and filled with coloured epoxy.
