Omega constellation movement

Which movement is better, Omega 564 or 75 1?

Omega 75 1 movement is good.

1, Omega 564 movement, Omega top movement 564 old European abalone 564 observatory five-way adjustment, 24-diamond automatic single calendar rose gold movement. Brand-new movement, accurate time, fast calendar dial.

2. Omega 75 1 is the CAL of Omega. 75 1 is the last "collectible" movement of the Mechanical Self-winding Observatory. Daily life is full of magnetic fields, and most movements will be magnetized when they are exposed to magnetic forces for a long time. The oris movement is specially equipped with diamagnetic components, and has experienced an environment of 2250 gauss in the famous LabouratoireDubois laboratory. It is stipulated to be exposed to an environment of 200 gauss, and to be accurate within 30 seconds. The test results show that when the magnetic force exceeds 1 1 times, the travel time accuracy reaches one third of the allowable deviation.
