Compass size

[Ginner]

Odd question I know, but are all dive compasses the same diameter. I have a cressi console with the pressure, depth and compass, the compass is broken(the bezel ring fell out on a recent dive), so I need to replace just the compass hence the question, will any make compass fit in the console housing. Thanks

Looking at the selection I have - no, they are not standard.
