Perhaps these were isolated incidents but I have had other watchmakers report replacement bridges with numbers.

Both replacements came complete with movement numbers. In two instances over the years I have had occasion to replace escape wheel bridges in cal.

#OMEGA WATCH NUMBER SERIAL#

Omega never sold a replacement serial numbered bridge for repair, if needed they would supply a complete movement but this was done VERY RARELY. Omega simply added the dail and hands and installed the movement into the case. Most of the 432 movements were supplied pre assembled including the stem but not the dial.

The serial numbers will not indicate a actual date of production but will get you close + or- a year. That said, Omega did purchase and produce movements in batches especially chronometer grades. The statement that Omega did not make a 321 movement after 1960 is not correct at all, and in fact they assembled them from existing repair parts right up to mid 1968. But I also know he has been wrong many times in the past (sorry John please do not hate me my friend) mostly due to the bad record keeping by Omega prior to being sold to the Swatch group and the fact that they have not made an in-house case of movement after the 80's. Diethelm well and having communicated with him many times, I can say he is verry knolageable in most cases. (Being relatively new to TRF, I trust it is OK to link to other forums so long as the thread is informative rather than controversial.) Again, the 'part's bin' factor could result in a '65' caseback being used in the assembly of a watch in 1969.ДЇor an interesting discussion relating to this issue, check out this thread regarding cal. Note that some use the date engraved inside the caseback of vintage Speedies (i.e., 105.012-65) as the watch's year of manufacture. (My 105.012 Speedy just returned from its first repair, a 'mainspring transplant', after 40+ years of enjoyment.) Your 'precious' will give you years of reliable service regardless of its age. If you buy pre-owned, don't even worry about dating your Speedy.

If you buy a new Speedy Pro (which I have never done and do not recommend anyone to do), just use the date on your receipt and enjoy. I'm not a mathematician but the probability of the movement/bridge numbers providing any useful (i.e., accurate) information regarding date of manufacture is negligible in my opinion.ДЄnd how do we really date a Speedy Pro? Is it the date the bridge was machined and engraved, the date the movement was assembled, the date the watch was assembled, the date the watch left Bienne, or the date it was sold at retail? Likewise, a movement assembled in 1996 could sit on the shelf for years until being installed in a case in 2008. The parts bin could conceivably contain bridges manufactured and numbered in 1996, or any year since, creating the possibility that a movement assembled in 2008 might have a bridge number dating from 1996. 1863 has been in production since the mid-1990s. Obviously, the parts bin may contain a mixture of bridges produced over the years a particular movement was produced. It may be some time (even years) before an assembled movement is installed in a case.

No one takes the time or the effort to insure 'first in, first out'. Again these movements are randomly pulled for installation in the cases. Once assembled, the movements are 'put on the shelf' for later installation in the cases. Note that this selection process might permit a bridge to sit in a bin for years before being used. No one takes the time to remove them from the bins in order i.e., first in, first out. As they are machined and engraved, these individually numbered bridges are collectively placed in parts bins awaiting assembly into the movements.Дuring the assembly process, these numbered bridges are randomly selected from the bins and installed along with the other parts. (On later model Speedy Pros, this number is also engraved on the back of the 7:00 lug.) Most refer to this as the movement number but more accurately, this number should be called the 'escape wheel bridge' number. Here's the problem with using Ryan's chart (or any chart for that matter):Д®very Speedy Pro has a unique number on the escape wheel bridge.
