Hi,
Sorry it took so long to reply... I've been at repgeek too much lately and forgot I posted this topic!
I did receive the watch in the end, only five days after I made the purchase - so it seems as if they are pretty reputable!
The watch looks just like the ones in the photos - not the real one at the top, but their own pictures that they have taken. I have since moved the bezel to a better position (stupidly with superglue, which almost cost me some layers of skin on my fingers), but it's a pretty good watch, although I know that the proper sellers from here, RWI and repgeek sell better watches for less money than topswiss.co.uk!!
I'm not sure if it's really swiss ETA, as I don't know much about these things, but it's definitely an automatic movement.
I'm not sure if I can recommend topswiss whole heartedly, as I wouldn't want to say definitely go for it and then someone gets gipped, especially as I'm sure they probably use asia clone movements and the watches are overpriced if so - but my purchase worked out very well, so I'm fairly sure that they are good people.
