Chubsmaster
路One aspect that could help clarify the discussion (at least for me) is the number of watches being discussed. It's seems there are only a few, perhaps as few as 7. I have read conclusions stating as many as 70 to 100 or other statements that seem to indicate there are many watches. But we keep coming back to one, two, or as many as seven.
From our discussion here, I think we have agreed that any watch with only a dial is illegitimate, so my assumption is that we would only raise evidence from a watch that has all elements except the case and 5.5mm pushers. Again, those are very few. There may be many watches with only the AS dial but if we agreed that they are not legitimate then we can ignore those, correct? (I am assuming the 286, 288, 416, 461 and 468 all have every element except the 5.5mm pushers, which we are referring to as the AS Demarchi group.)
The reason I bring this up is frankly, it is problematic to me to draw conclusions about an entire production based on an oddball watch or two. I now understand why people approach this with scepticism.
Also, did you have a follow up discussion with Omega regarding the other elements besides the serial number? I myself would not be able to draw a conclusion about whether a watch is authentic based on this one discussion with Omega. Omega simply did what everyone does when evaluating a watch, they went to the most obvious data point, which was the serial number. No sense looking further if the first data is incorrect. So once you determined the 416 was a normal speedmaster shipped to De Marchi, what did they say next? (I apologize if this was already discussed.)
From what I have read thus far, the 416 does not have an extract from Omega stating it was transformed but the 468 does have an extract saying it was transformed. Is this an accurate statement?
I am not sure about 286 and 288... I don't know the movement numbers.
Attached is the invoice where 416, 461, 468 and 469 come from.
Dials and bracelets are correct. The other important element is the number of the watch itself.
I am not aware of many AS with 5.5mm that have numbers above 400 (like #476, delivered in Torino in May 1976). The pieces identified as "De Marchi's" all have high numbers, no repeated numbers have been found, so there are around 70 watches that could be AS 5.5mm or AS 5mm. Actually to my knowledge there are more AS De Marchi's 5mm identified above the 400 number, than AS Bienne 5.5mm... This last statement justifies the relevance of the AS De Marchi watch.
In my opinion there is enough supporting data, and well defined boundaries.
Yes, there is room to be "skeptical", and we all have an individual "threshold".
The "skeptical" view can be applied to many other vintage Speedmasters (60's/70's racing dials variations grey/black, Ultraman, straight writing/racing dial for Japan, grey/blue dials, Meister, moonphase dial variations, etc, etc...). For many of these watches you only need to replace a dial, or a caseback (not even both components), with no worries about a limited edition number, in some cases not even worry where the watch was originally shipped too, and do so on a Speedmaster from the same era, to create "something".
The AS De Marchi watch, for some reason, has been scrutinized far more than others, which is ok, so, as a consequence, more work has been done to sustain where we are on the AS De Marchi... Far more research as compared to many Ultraman or Racing dials watches that have been sold in recent years.
I am only sharing my thoughts, not trying to convince anyone.
Take care
