Hi all. I have an Omega De ville which needs a new crystal. It’s a 166.0086 but can’t find it anywhere online.

Any assistance appreciated!
Cheers

You need an Omega PX5106 (That is the version with the gold tension ring)
There are some available on ebay. Maybe you can also find it somewhere else as well.

Amazing thank you! No way I would have known that! Looks to be around £100-150 on eBay. That sound about right?

Looks like the crystal has the follwoing dimensions:

Diameter: 31.60 mm
Height: 4.0 mm
(I do not have a parts account, so if someone has better info they might correct me)

Depending on how much value you put on originality, you can also get a generic high domed acrylic crystal with a gold tension ring for much cheaper. It will work but not have the little Omega logo in the center of the crystal.

Appreciate that. Thanks for responding.
