Did you read what I said? Do you have a basic understanding of why a watch would get a new dial at 5 years old in a perfect watch when factory serviced?
Have you ever seen the variation in 321 service dials? Everything I stated is completly in-line with how Omega services watches and most likely stocks service dials.
Occams Razor dictates the easiest most plausible explanation is the most likely. The odds of a factory prototype is extremely low, and an extract will with 90% certainty disprove it, and I’m 99% sure the way extract will not prototype. The problem is an extract can be argued not to have this info or a prototype dial found its way into production.
At the end of the day there is no way to 100% prove one way or another. You can believe what you want but everyone else is thinking service or redial. I personally don’t believe it’s a redial, but another service dial from a small batch.
