Omega always releases LE linked to a specific year. So it should be around 1950 to 54. For production purplses, Omega might have ordered dials before the Moulinsart issues reached to an end.
Thank you, Friendharry. I believe that is generally correct for Omega to have, where possible, a link to a year and this only makes sense in creating a LE; however, there are also some tenuous (playful maybe) links for example the Speedy Ann with 5957 pieces. There are a number of departures, I believe, which make it a rule of thumb rather than a given, eg:
Omega Seamaster 300 "Spectre" Limited Edition. Available in a numbered series of x/7,007 pieces.
James Bond 40th Anniversary Limited Edition Ref. 2537.80.00. Limited Edition number: x/10,007
Speedmaster Apollo XI 1969 Yellow Gold: 1014
Speedmaster Apollo XI 1980 Yellow Gold: 300
Speedmaster Apollo XI 20th Anniversary: 6000 (numbered 2000 USA, unnumbered 4000 rest of world)
Speedmaster Apollo XI 35th Anniversary: 3500
Speedmaster 50th Ann. (Gold seahorse): 5957
Apollo XI 40th Ann: 7969 (again the link in the last two digits)
I think the Japanese Mitsukoshi had only 300 pieces.
Thinking on your point, It may also possible that Omega were aiming for a 60th year anniversary of the publication with an LE of 6000 as seen with the 100 multiplier as in the Apollo XI 35th LE but cut short production on the breakdown of the deal as the stats would suggest. Or it could have been 2014 as Dubois and you suggest, citing how Omega settled on the LE of 2004 for the "Japan racing" edition. Either way, using the "German a Tank Problem" formula given the serial numbers seen to date with one sample in the 900s we are looking at circa 1000 pieces known predicated on consecutive serial end numbers alone.
I would hazard a guess that this would have Been slated as a LE rather than a numbered edition. Of course what we have here is neither a limited edition or a numbered edition. It is a true Omega blip, and until someone at Omega talks we will be continually guessing. However, in the meantime, the historical accuracy of the GTP formula is legendary, I just hope I have applied it correctly - we must have a statistician or mathematician member somewhere.
