happy to share my observations of pre-purchase and post...
It seems that stock allocation has been sparse, when i was buying watch in first week of June i did a lot of searching and it seems like independent ADs maybe would have 1-2 stock items, you could either see that on website if they publish this info or when i call them and ask... I also found difficulties with Mappin & Webb who had one in stock, it was sold and when i asked to call me back with re-stock forecast, they never did.
Then post-purchase I noticed that Omega stopped selling it on their website and in July i called Omega Regent St in London and asked about its availability, they said sorry last piece was sold recently and they could not answer when or if they will ever get it in stock....
