I just returned from the UK and France. Visited a number of Omega boutiques, but none had the Globemaster in stock. The Oxford Street boutique in London had only had a single example, which had been sold. I'm keen to see if any of my local stores have it now I'm home.
And to follow up on my earlier question about exchange rates and so on: I think now is a fantastic time to buy a watch if you're visiting the EU. To my regret, I did not. But, for example, the Explorer 2 (ref 216570) is currently 7000 Euros, which would work out to at least a $2000 savings over US retail. The price at Heathrow duty free was also pretty good at £4458, also a pretty good savings over US retail.
To my regret, I didn't have time in Paris to buy the watch and having just recently bought the Spectre Seamaster my wife thought I should wait at least a couple more weeks before buying (yet) another watch. Oh, well.
C'est la vie!
