This is something I really only found out last night, but thought I would share. When doing a project, try and keep it as consistent as possible. Mixing features is not a problem, as long as they all blend...
What happened, was I tried to put the Snowflake dial into my vintage sub. I thought, why not have the nice clear dial, in the case I like to wear? Well, I tried it, but strangely, felt that it just didn't go. I think the problem, was the square indices clashed with the more curved sides of the older case design, and the color of the dial and markers looked 'too new' for the aged case. Not something I would have previously considered, but a very noticeable effect, in that, for no apparent reason, it 'looked wrong'. Not wrong in the sense of mixed parts, but wrong in an aesthetic sense...
So for anyone planning or working on a project, I would say be consistent in your plan. If you want modern, keep it all modern, if you want it vintage, keep it all vintage, and remember that not all dials will work with a certain case-shape
