Dial size for Omega Cosmic Moonphase (2486 vs 2471)

Regarding the placement of the dial feet I can only assume they are located in the same spot on both dials as either dial attaches to a cal 381.

A 2486 dial is larger that's for sure, the difference in mm I cant say but here's a pic with from left to right a 2471, a 2486 in the middle a 2606 on the right. The difference in size can clearly be seen and although I've never tried it I'm certain the 2486 dial will not fit a 2471 or 2606 case.

Also important to note is the difference in design between the larger 2486 and the smaller 2471 and 2606 dials. A 2486 dial always has the minute track outside of the date track and with a 2471/2606 it is always the date track outside of the minute track.
