Had a look myself yesterday.
The Omega museum was still quoting CHF 75 -

However when you click through the link it says CHF 120 as stated by Gatorcpa above. Pretty disappointing as I've been meaning to get a few.
The thing I'm not sure about is whether they add VAT on top?
Can you opt to pay in CHF and hope for a better exchange rate on your credit card?
