Hi everybody! Looking for a Speedy of 1986. The serial number can help to date a watch when it came without paper it seems. I found different kind of grid. https://est1897.co.uk/omega-serial-numbers-how-old-is-your-omega-watch They told that for Speedy, it's a bit different scale, with small gap compare to the other model. Between 47-48.000.00 one a source, 49-50.000.000 from an other. Moreover, between use of movements number listing, and case number, I’m a bit lost. Can anyone light me in this point? Perhaps some people with 86’s Speedy with papers to compare with the grids? Thanks in advance
Yes that site is brilliant and comes closer to the production date (probably) than the good old Speedmaster serial table http://chronomaddox.com/romans.html where an ‘86 should have a serial no of 47.XXX.XXX but below 47.25X.XXX. That table is not entirely accurate. I have a Speedy with serial 47.133.XXX with a production date in april 1985 according to the extract from the Omega archives.
