1970 Constellation Crystal - Can you help?

[BertieBoy]

Hi,

newbie here - been considering this omega from a UK seller, only thing bugging me is the crystal.. can anyone confirm if the crystal from this year/model is accurate as it looks quite rounded and not flat crystal, maybe this was the original al style I am not sure but appreciate help!!

also is the original acrylic or glass?

It's an acrylic crystal and has a slightly domed profile.
I see no issue with the crystal based on this pics.

Mine for reference.

I can't see any issue from the photos either, no guarantee it's original though - being UK it's possible it's not, as only aftermarket crystals are from UK
