Good morning everyone. I am trying to find the Omega crystal number for my Dynamic (1969). Omega Vintage lists the case ref# as 166.0039. I have gone to Otto Frei and they list a 166.003 with corresponding omega crystal 063PZ5143 (no cyclops, white ring). They cannot confirm that this is the correct crystal due to the additional 9 in the case ref#. Additionally, they are out of this crystal. So, if it is the correct crystal, I still need another source for it. Thanks in advance for any help or suggestions.
