Hei.
Jeg har en Ploprof600 fra 1970.
Den har caliber 1001, men ser at 1002 er den ”normale“.
Noen her som vet noe om hvorfor noen av ploprofene har caliber 1001?
"-MOVEMENT
Prototypes are often seen with the 1000 calibre movement but in later iterations and with the retail watches the 1002 movement was standard.
This was an enormously robust movement. Probably one of the very last movements exclusively designed by Omega and it was a high beat 28800vph with instantaneous date change at midnight and first issued in 1968.
This was a very common movement with over 370,000 made but it experienced occasional longevity problems. So when a watch was presented for service a movement was swapped out in its entirety.
This has given rise to over 60% of sampled watches having undergone a movement swap."
The aim of this website is to assist watch collectors in correctly identifying the Omega Seamaster 600 Ploprof in all its variations.

1000/1001/1002 er fra 1968-69.
1001 og 1002 ser ut til å bli "forbedret" utgaver av 1000.
De var opprinnelig brukt i Constellation linjen tror jeg, men gikk også i andre klokker.
1001 var "Certified Chronometer" 5pos/5temp. utgaven.
Det er sagt at det var de siste
inhouse urverk Omega produserte på grunn av kvartskrisen som startet skiftet mot bruken av modifiserte ETA urverk.
-"The 1000 series was one of the best-selling of all Omega self-winding calibres. More than 1.5 million were used not only as certified chronometers in Constellations, but also the uncertified movements in Seamasters, Geneve and Speedmasters.
The certified chronometer calibre 1001 was the first of the series to power Constellations. Cal.1001 is a 20 Jewels automatic movement adjusted to 5 positions and temperature. It has a power reserve of 42 hours. Designed by Kurt Vogt under Alfred Rihs, it was an impressive 4.25mm thick. Apart from its high frequency (28,800bph), it incorporated a number of technologies, such as a hacking feature to allow more accurate time setting, instantaneous date and a thinner rotor to slow down and create less stress and wear on the winding mechanism."
