  1960 NASA pyysi Bulovalta tietokoneisiinsa kelloa. Näin Bulovan kelloista tuli osa 46:tta eri Nasan tehtävää. Myöhemmin NASA etsi Apollo-lentoja varten astronauteille sopivaa rannekelloa, vaihtoehtona olivat Bulova ja Omega. Kilpailun voitti sveitsiläisen Omegan valmistama Speedmaster, josta tuli virallinen kuukello. 

  Omega Constellation ST 368.0852  Caliber 1011 kello on yhä erinomaisessa kunnossa .Kellon pohjassa on kohokuva observatoriosta, se tarkoittaa, että kello on läpäissyt sveitsiläisen kronografi testin ja tarkkuus on erinomainen mekaaniselle kellolle. Minulla on myös esite kellosta jäljellä.

 OMEGA Caliber

1000 Miesten automaatti, joka tuli tuotantoon 1969. Koneiston valmistaja oli Lemania-tehdas. Tuotanto sarjalla päättyi 1984.  koneiston mitat: koneiston halkaisija 27,90 mm ja korkeus 4,25 mm.
17 kiveä, Inca-iskusuoja, heilahdustaajuus 28.800, käyntivara 42 tuntia, kalenteri, keskisekunnin pysäytys nuppi ylösnostettaessa, rukkauksen hienosäätö.
1001 Sama kuin 1000, 20 kiveä, cronometrikäynti-testattu
1002 Sama kuin 1001, ei cronometritestattu.

1010 Parannettu versio kaliiperista 1000.
1011 Sama kuin 1010, 23 kiveä, cronometrikäynti-testattu
1012 Sama kuin 1011, ei cronometritestattu.

1020 Sama kuin 1010, day/date kalenteri
1021 Sama kuin 1011, day/date kalenteri, cronometrikäynti-testattu
1022 Sama kuin 1021, ei cronometritestattu.

1030 Sama kuin 1010, mutta vedettävä koneisto, ei automaatti.
1035 Sama kuin 1010, mutta vedettävä koneisto, ei automaatti, ei kalenteria.

 Omega – Calibre 1011

Calibre 1001 and 1002 are best avoided, except by those who can repair and maintain them. Much discussionabout early 1000 series calibres has occurred above and so no further attention will be paid to these calibres.Incidentally, during the preparation of this article.The date model calibre 1011, with an additional six jewels added to the upper and lower winding system over the base calibre 1010 will always carry the COSC “Officially Certified Chronometer” appellation on the dial. 

This is one major way in which to determine, without opening the back of the watch, if it left the factory with a certified movement. Naturally, it’s essential to see pictures of the movement to ensure that movement dial and case belong together and also to gain some impression of the condition of the movement. 1011s were sold between 1972 and 1979 in a range of cases including the C-Shaped with knurled bezel and the famous integrated bracelet line. 

Many of the cases were sealed with four screws and it’s important that you do not succumb to protestations about the difficulty of opening these cases. In collecting these calibres, it’s essential that you confirm that they are marked on the movement as chronometers. 

A well looked-after and regulated calibre 1011 will serve you well – a neglected one may cause you much trouble. Make a point of asking about service history or choose to purchase recently serviced examples of this calibre.

Are they collectible? I believe good examples that have been treated well will increase in value over time, particularly the solid gold and stainless steel examples with rounded-square dials and integrated bracelets. Models 368.0852, the Octagonal model 368.0855 with the rounded square dial opening with 14K solid gold bezel and integrated steel/gold bracelet, and the rounded case 368.0850 are selling at the level C-Shaped calibre 564s were sold two years ago and represent good value.

Kronometrillä tarkoitetaan kellon koneistoa, joka on läpäissyt puolueettoman sveitsiläisen tarkastuselimen, "C.O.S.C" (Contôle Officiel Suisse de Chronomètres) tarkkuustestit. 

Näissä testeissä koneistoa testataan eri asennoissa noin kahden viikon ajan ja jos tarkkuus on riittävän hyvä, saa kello COSC sertifikaatin ja voi käyttää nimitystä "Certified Chronometer". 

Founded in its current form in 1973, the COSC is a Swiss non-profit organization that tests Swiss-made chronometers. COSC is an acronym for the organization's French name, Contrôle Officiel Suisse des Chronomètres.COSC testing generally applies to watches manufactured/assembled in Switzerland. 

Notwithstanding, the normative standards are set by international agreement and are the same whether they are nominally labeled ISO or DIN standards. Some German, Japanese, and even non-certified Swiss movements can surpass the normative requirements. 

The Japanese have largely abandoned the accolade, replacing it with in-house testing to a slightly more strict standard as with, for example, the Grand Seiko. On the other hand, the Germans have set up their own testing facility in Saxony at the Glashütte Observatory where the DIN 8319 standards, which mirror the ISO standards used by COSC, are employed. 

At one time the French provided similar large scale testing at the Observatory at Besançon, however, today only a very few watches are currently tested there and carry the accolade "Observatory Chronometer."The COSC was founded by five watchmaking cantons (administrative divisions, similar to states in the U.S.A.) of Switzerland: Bern, Geneva, Neuchâtel, Solothurn and Vaud, together with the Federation of the Swiss Watch Industry (FHS). 

It encompasses the laboratories/observatories that had been created independently of each other from the late 19th century.Three laboratories now test the movements submitted by individual watch manufacturers to be granted chronometer status. 

They are in Biel/Bienne, Geneva and Le Locle. The Geneva and Biel laboratories are almost entirely devoted to testing Rolex movements. Although not all Rolex watches are chronometers, Breitling has claimed that since 2000 all of its production is COSC certified. Omega also has much of its production certified. 

Thus, based upon the movements used by Rolex, Breitling, and Omega, the movement calibers that obtain most of the COSC certificates are the Rolex 3135 (since 1988) (and variants 3155, 3175, 3185, 4130) and 2235, the ETA 2892A2 (and variants) and Valjoux 7750, each of which operates at 28,800 beats per hour.
