I was thinking of going Swiss too, but everywhere seems to be out if stock. A lot of people recomend sticking with the Asian, as they seem to be very reliable compared to most other one movement, then if they die do a swap then.
You can pick up a good ETA from a reputable dealer that hasn't been played with (ie straight from eta) for around £100 so would be better to wait till if you need it and swap it over then, at least from what I've learnt that's my plan anyway!!
Got a response back from Anguses people today saying delay will be just over a week due to the recent crackdown for QC picks.
