hello everyone, i gave my partner this very well kept omega. i wanted to know more about the movement and how it works. two or three times a day she has to reset the time because it stops. she winds it by turning the crown and it starts again. is this normal? isn't it automatic by moving the wrist? thanks.

Hi. This Omega movement looks like it may be missing the rotor/weight for the movement. Cannot fully confirm unless you tell us the caliber number or have better pictures of the caliber/movement. But I can already see where the rotor may be attached, which is needed to wind the spring. You can also wind the watch with the crown, but I am assuming your partner is not winding it enough to keep it running for a long time.

Looks like a manual wind watch to me. Try winding it for 20 turns or so or until it gives some resistance. Then see how long it runs. Can you take focused photos of inside caseback and also of the movement so we can read the numbers- your photos are very blurry.

It’s not automatic. Just a hand winding movement. Automatic movements have a rotor, and usually say automatic on the dial.

She needs to keep turning the crown until it can’t be turned any more. Then it should run for more than a day.

This looks like a caliber 620, which is a manual movement. You can also tell that it’s not automatic from the flat caseback as there’s no room for a rotor. It needs a service if you have to wind it multiple times a day.

Manual wind 620, should get at least 40 hours from a full wind if the movement is in good condition.
