Cases that fit Orient 46943 Movement

Hi, I have an old Orient Blue Mako that still runs decently, but the day dial is broken. (This is after I tried to get it repaired one time)

So, if I remove the day dial button located at 1 o’clock position. What case or size case would fit this movement, Orient Cal. 46943?

I hope to do some heavy modding (new case, new bezel, new bezel insert). I found a dial and hands from theyobokies.com
