Omega 166.0207 / 366.0843 cristal reference and second hand

jbw · Jun 21, 2026

Hi everybody.

I don't arrive to find the cristal reference for this model.
Do you have an idea?

Also, the second hand doesn't move, but minut and hour are ok.
do you know the reason please?

Thanks a lot
Jean-Baptiste

Emmy lists the crystal as: PX5289 for the gold one.

Second hand not moving means it needs a trip to a watchmaker 😀 The second pinion on the 1010 movement that is not part of the normal gear train, it is off to the side on another wheel. It is held in place by a little spring. IF this gear is not lined up correctly, or the pinion got bent, or the second hand was jammed on without a proper movement holder (or a million other causes!), it can not move.

Hello, thank you. I open it and I make it. It’s okay. The wheel was not higher enough. Thanks a lot. It helped me. Thank you!!!!
