Hey folks,

A few weeks ago I bought a Vintage Omega 2480 - 1 Automatic from a watch collector in Holland. Here are some specifications of the watch.

Model : Omega 2480-1
Diameter : 37 mm
Age : 1947 ( 11 mil )
Movement : Automatic bumper cal 351

So far so good, I wound the watch 10 to 15 times and it was working fine. During the first evening I've found out that the watch was giving me the incorrect time . I did some tests during the week and I've found out that that my second hand stops between 10 and 11. If i tick the glass or bumb the movment / winding , it wil continue. Sometimes the watch works great, but i Can't deny that the watch stops.

I went back to the previous owner but he tells me, that he never had any problems with the movement.

Now i'm wondering if someone in our community had some similar problems ? I went to 2 different watchmakers but they can't figure out whats wrong.

Thanks for helping.

Is the hand hitting something at that point anywhere inside the watch or on the other hands? Or maybe, could it be a gear tooth missing somewhere? In any case, if last service is uknown it's always adviceable go for it before a daily wear.

A watchmaker with experience in vintage watches can sort that out for you. By the way, wind the crown 10 to 15 turns is why it stops.WIND IT! Wind the crown 40 or so turns. If the watch is in at least decent condition, wind it that much will not do it any harm. Service history unknown? Have it serviced.

Mr Canuck is right. That bumper only winds in one direction, so you need to give it a good start, so winding a lot by hand will help that.

If that doesn't do it, off to the watchmaker.

Does it have a genuine Omega crystal? I have had the hands rub on some aftermarket crystals.

Thanks for your help.

One thing i forgot to mention is, when I'm setting the time correct it seems like there is a bit of play on the hands when I'm turning the crown.

That shouldn't be a problem. That movement has "indirect center seconds", which means there's an intermediate wheel for the second hand.

Thanks Tom,

Well it's more like that the whole dial section is wobbling from left to right when im turning the crown clock / anti clockwise. Should this not be locked ? I will post a video tomorrow maybe this will explain it better. Thanks everyone.

That implies the movement is loose in the case. Off to the watchmaker!

Most likely missing a case clamp.

You need to find new watchmakers.

Looks like case clamps are loose or missing.

Second hand is too long and it is a generic one, not original Omega.
Cut it short and bend it a bit may help.

No idea about case clamp.

May I ask what second sweep / hand should be on top ? I Guess the size would be something like this right it has the same 351Cal.?
