A while back I put together a watch with the case #1 from Ofrei. The dial was 28.5mm. I really did not care for the dial, it did not really pop out. I would call the style "70's Timex". If you take the TZ watchmaker level 1 class you will start with this watch case. I looked around and did not see any other dials that were 28.5mm; but of course by today's big watch standard this is very small dial. The Ofrei #1 case is 37mm or 38mm. I also found the generic SUB which case is 40mm or Explorer also use the 28.5mm dial. I think "FoxInt" can help find both of the Sub and Explorer cases.
Here is a photo of the Ofrei #1 watch case, dial and hands:
The dials I made are simple and with silver markers in the Calf-Style. The numbers are 3mm tall. The dial feet will fit the ETA 2824-2 and if shortened the ETA 2892-2. At 6 it says "AUTOMATIC" and at the bottom at 6 "SWISS MOVT". I also made some small initials for 12 position and I think these are 2mm or 3mm. Here are the four color dials I made:
