BASE1000
·- limited edition of 500 (the serial number of each one movement must exactly fit into a determined range 39.180.xxx - 39.181.xxx)
(it is mandatory to obtain a specific extract of archives from Omega)
Well, it seems like this information is not completely correct. Marco Richon writes in his book 'a journey through time', that beside the 500 watches from Bienne there was a special edition issued by the Italian market itself, which carries on the outside of the caseback the 'i' for Italy and the omega sign in a circle as well as the engraved number in between.
Data gathered by various collectors in Italy suggests that Omega Bienne, in fact, produced only about 350 pieces of this model by his own, whereas another 150 were produced under license by Fratelli De Marchi, the Omega licensee in Italy, Torino at this time. Because no two of these watches have ever been found that share the same limited edition number.
Collectors of the very early Speedmasters know about this kind of license-partner-watches, because nowadays it makes no sense for example to order an extract of the archives for a 2915 or an early 2998, as Omega will not provide any further information than the fact, that the watch (not specified!) was produced under license of Lemania at l'Orient and delivered to this or that country under this or that date.
The Fratelli De Marchi Apollo Soyuz are similar kind of license partner watches. The museum can not recognize from the Omega factory records which of the outgoing Speedmaster became one of the limited Apollo Soyuz series in Italy. The records do also not contain any note about the engraved consecutive numbering on the caseback. It seems only clear that the factory delivered the relevant movements in summer 1975 to De Marchi and that they carried numbers around 32.xxx.xxx whereas the Biel assembled models carry 39.xxx.xxx movements and were delivered to the agents not before 1976. To my knowledge this watches went to Italy as well. I have never heard or seen anything about a different destiny than Italy.
After all the 'Fratelli De Marchi' matter is one of the very interesting but still not completely unveiled question around the mysteries of this famous and very first LE Speedmaster. However there is no doubt in what mstanga says, that this watch shows up extremely rare, maybe one example every 3 years. This makes it more than likely that no more than 500 items in total were issued to the market. Let me compare the Soyuz with the ST 345.0809 moonphase from 1985 with also no more than 1300 unites produced. Although this watch is similar collectible and iconic, it can be sourced any time if you are ready for an international transaction or/ and to pay a serious amount, whereas the 500 Soyuz 's disappeared practically from the market.
