I think we need Desmond to adjudicate here, ‘cos now I’m getting confused, and i have been studying these for 11 years or more
certainly, from OAJTT, Omega themselves called these dials 12-sided sun Silvered brushed Dials for the .004 references. omega never used the term “pie pan”
but.....the dial shown has a distinct ledge Or step ( there was another thread recently here that discussed these step Dials)
In one of Desmonds essays,

Desmond called a very similar dial, again in a .004, a convex dial
Could it be that there IS a real distinction between what we have been calling “pie-pan” dials ( noting that Omega never used this term) ie
- a true 12-sided “pie pan” does need a step or ledge
- these other “pseudo” 12-sided dials, without a true ledge or step, maybe are not truly “pie pans“ after all, and should really be called convex dials?
another thought is that Omega changed the design sometime during the .004s lifetime, or simply changed supplier ?
