The substance of my comment however remains, as I cannot like the timing of a thread that advertises and discusses in detail a watch up for sale only 3 weeks later --- whether you own the watch or the auction house selling it. For optical reasons, I would have made the same post as you, which is technically interesting, but only after the sale was done. But it's up to the moderators, not me, to decide whether this post should stay.
In any event, glad to know you are confident everything is original with the watch -- in which case, it's definitely a nice example of a Tudor. I look forward to more contributions from you on this forum ;-) Cheers.
