Are you asking me or Warren? If me, that shot is from a member who bought from an AD we all know. I've got a few shots of my vintage watches too, and they all look close to the shot I posted of the Speedmaster's symbol.
The crystal on my modern Speedie (3577.50) looks like this one: But the crystal on my vintage 166.0033 De Ville looks like this one:
Well actually it may be that neither of them is correct for a "old vintage crystal". It should look like the vintage Omega symbol. However Omega changed these during a time period that might be described as "more modern vintage" ( yes, I know, here we go again, what is vintage) Here are some shots.
What exactly is your concern with the symbols? Is it the happy feet? I've just checked my vintage De Ville again in decent light and the symbol is elongated vertically, without happy feet... as you say, matching the Omega symbol on the dial.
From my point there is no concern. For one thing, if someone wanted to copy these it would not be difficult at all.
Here is one on my Memomatic for comparison. This glass was fitted by Omega Bienne while in for restoration. Willie
Like on the dials, crowns and buckles, the Omega logo changed over the years. I don't think it matters much to collectors. While it's always nice to know that these were the original parts that the watch had when it left the factory, these are wear items that were routinely replaced during normal servicing. Would you really want a car with 50-year old windshield wipers or the orginal oil filter inside? I think not. Just give me the correct replacements. gatorcpa
Even if the car isn't driven the wipers are going to be cracked and nasty. Let's not even discuss oil & filter. Ya gotta do what you gotta do. gatorcpa
