Would anyone consider Tiffany Factory Geneva?
So, I am going to answer your question in a sort of generic way; sort of as an answer to a lot of possible speculation... and this is my sort of my reasonably educated guess only. I have looked and looked at rattrapante movements from this approximate time period. There are a lot of brands which seem to have used an ebauche with the same style and basic mechanical function at the watch in the original post.
Yes, I can find a couple of Tiffany marked movements which look generically like it. As I said, I can find a lot of branded or attributed movements from the time period with the same basic layout from pinion locations, to lever and bridge shapes, to location of column wheel and on and on. It seems that someone/some maker was building the basic ebauche for a lot of people.
My impression of the "Tiffany Factory" was that anything very complicated they turned out started somewhere else??
This has always been my problem with Swiss watches. When I started collecting with my dad and in my early years on my own, this problem was enough of a frustration to keep me away from Swiss. Now it is becoming sort of an intriguing frustration.
I learned a long time ago from my old man that, just because someone calls an unmarked watch a Patek and shows you a marked Patek that looks pretty much the same, unmarked watches with lesser finishes are never Pateks...until somebody offers to buy it whips out Patek money...then it doesn't really matter to the seller anyway...it matters to the buyer and the seller just counts the money.
