Need help removing Omega 1430 winding stem

Hi there,

I am new to the forum and have a great Seamaster 1340 that I inherited from my dad. The crown fell off the stem and I need to remove the stem to properly mount the crown back on. I can not see where the release for the stem is on this watch. Any help would be greatly appreciated.

Best Regards,

Paul

Helpful as usual.

I would if I knew how. You said you knew how, but wouldn't.

Thanks for the hint Canuck and thank you for correcting my dyslexia.

I did bring it to an Omega certified watch maker and spent $500 for a new crystal, reattaching the crown, and a new battery. One year later the crown unscrewed from the stem again. It is not broken, it was just never re-attached properly.

Being an engineer that designs and builds semiconductor metrology microscopes that have a precision in the sum-nanometer range, I think I can handle this challenge.

It is clear to me that the stem needs to be removed for me to properly attach the crown as the stem can not be held still while in the watch. I am sure this is what happened last time the service was done. I know I need to remove the stem, hold it still, and re-attach the crown with high strength thread locker.

I have not found any clear information on line on how to remove the stem and do not want to be hasty and start unscrewing parts that are holding other critical pieces in place.

I am not trying to take work away from qualified watchmakers who clearly know more about these time pieces than I do, I am just trying to fix something that was never repaired properly in the first place.

Thanks,

Paul

The key missing link was the 255.111 part number. Got it. Thanks.

Paul, once the stem is out, use some fine pliers to hold the stem as close as you can on the upper end. Then it can not snap, when you screw on the crown with some pressure. One drop of Loctite on the stem will do it. Needs a bit of drying time . But you know this.

Thanks for the tip. I have heard these can be brittle.
