So many brands use movements based on the ETA2892 (e.g. Omega 1120, Longines L619.2, etc). However only some have full parts interchangeability because some brands modified their movements to have longer power reserve etc.

Is there a good source or easy way to figure out which 2892-based movements were "off-the-shelf" (i.e. the same except for the brand name on the rotor)? Or (probably wishful thinking) a source for which specific parts in a movement like the l619.2 were modified from original? Caliber corner and watchbase have been helpful and are great resources but they don't usually help on these specific questions.

Good people of r/watches, wondering if you can point me in the right direction. I like the Monta Noble and wondering what other similar pieces there are. Nothing against miyota, the sw200 or other common auto movements but I am curious about this specific 2892/sw300 niche. Vintage or new, microbrand or big brand.
