I have nothing better to do so I thought I would show a few pictures of my dial experiment. I haven't seen this done before, but then I didn't look too hard. I took a flat service dial and turned down the outer edge creating a step. It was my first attempt so I think I over did the step. Anyway I then had it refinished and re lumed. With a bit of adjustment on the cutting It might make a good looking refinished dial. Has anyone else tried this shenanigans?

 

Concentric Circles?

 

Those subdials look super deep.. did you press those too?

 

How exactly did you manage that?

 

Have you tried to attach the dial to a movement? I suspect the dial is too high to install the 3 center hands.

 

All I did was put the dial in chuck and turn down the edges. I didn't do anything else exept send it to the re finisher. He may have buffed it because my sharp step looks a bit rounded. It is a modern service dial that I bought new from Swatch. The back is flat. I had it on a movement but got sick of looking at it without the step. I figured that if I ruined it, no great loss. I could just buy another service dial. Here is the back.

 

I appluad the experimentation. For reference,

 

I think that next time, if there is a next time, I will also turn down the center also which will make the sub dials shallower. Now that I think of it, there won't be a next time.
