The "X-Reference" Mystery: Apollo XI 20th Anniversary with Gold Cal.863 & 345.0808 Case

Archer

The OP has not yet returned, but I'll lay out what I believe is the most likely scenario for how this information came to be on the form he has received.

First off, these X references do exist, and I have run across them many times. I am currently in the process of finding out more information on these from Omega - hope to have some answers tomorrow. But one thing I will say is that I have never searched on a serial number, and had the X reference come up.

The OP asked for a "deep dive" on this watch, and as someone who has done this many times, I know what the process is the person who did this would have followed. But first just to explain, the Omega Extranet has different ways of finding information, with three major areas where a search can be performed:

The first is a search by serial number, which will bring up a watch reference (PIC) number, and from there you can see all the details of the parts used for that reference. Note that this is the only search that will tie whatever information you get to a specific serial numbered watch.

The second is a search by reference (PIC) number.

The third is a search by individual component - this can be a part number for a case or for a movement. Once you pull up that specific part, you can search for the assemblies that part is used on.

So based on the logical steps, this is what likely what the technician did:

1 - Used the Omega Extranet to check the serial number. He did that and it returned the standard Speedmaster:

Serial number: 48272416
Article ref: 35925000

The case for this is 055ST1450808. But inside the case back the watch he has in his hands has 3450808...

2 - So the technician went to the section of the Extranet for a component search, and put in the case back number 3450808. That pulled up a case back, and there is a menu on that item that allows you to search for all cases, watches, movements used that are associated with that component. If you search on the case back, and select cases, then use that case result to search for watches, it comes up with the X number:

So the actual serial number pulls up a different watch - why I cannot say. But the claim the OP has made that the serial number is related to this X reference is not correct IMO. By serial number, it's not the X reference that comes up, but the 35925000. So the X reference is at this stage only tied to the case, not the watch serial number.

So what are the differences between these two watch references aside from the case?

The original dials were different part numbers:

X reference was dial was 064TP1472003.

3592 reference was 064TP3052001.

The bracelets were different:

X reference was 020ST1447805.

3592 reference was 020ST1498840.

The OP has neither of those on his watch, (1479/812) but since bracelets can be changed I don't put much stock in using that for any sort of determination.

Everything else is the same - hands, case parts (except for the case back).

When I look at the image that the Extranet pulls up for the X reference, it's grainy, but to my eye the Omega logo on the dial is an older style, narrow logo. The logo on the 35925000 is the more common rounded, modern Omega logo. That more modern logo is what is on the OP's watch, not the one from the X reference.

So why was this X reference put on the paper? Well clearly there was something different in the case back, so the deep dive required an explanation for that, and that is what the technician gave the OP. Unfortunately it has lead them to believe that this watch is something that I don't really think it is.

I would be interested to see if inside the case back both case numbers are present - 1450808 and 3450808. I've seen that before.

For me this is a 35925000, and nothing more, at least at this stage.

I think that it will remain a dream to find a particularity to this one...

it s a 3592 as the others as described

For me, following the country you can find different sets and documents

Unfortunately, the set sometimes doesn't match the watch, so it can't be used for identification. I also had a 3592 with a complete 20th anniversary set; either the authorized dealer made a mistake during the sale, or these are sets that were later reassembled, which is more common.

These do not indicate that the watch is a special edition, modification, or anything like that, but watches where the information was not able to be tied to a specific reference (PIC) number.
