I was able to feel it was a redial by looking at the OMEGA font and the printing. However, I did learn that the texture of the dial/tone is also an indicator. I thought the finish wasn't too bad. But it is off from original examples. I did compare with pictures of original dials for the Omega Triple Calendar 2606, but the store price threw me off.
I don't particularly trust the store owner of this example, but his lack of knowledge has given me great deals on watches and pocket watches before. But no matter the price, a redial is a no go for me. Thanks again OF.
