Apologies, it was Amazon I bought mine from. The exact one I got isn't available any more but this looks identical: https://www.amazon.com/dp/B00IOER6S8/ref=cm_sw_r_awd_QbZrwbY1AJR60
Search " demagnetiser " as those cheap Chinese ones are not something I would put a expensive watch over. Pay the coin and get a Cousins or equal quality. Cheap ones are 220v for the US boys
Just got one on ebay yesterday fro $10 worked great, I demagnetized all my watches accept one that keeps better time while is magnetized lol, actually my omega was keeping better time while magnetized too lol. -1s in 48h
Don't waste money on the cheap ones, good ones are only $95 from Labanda in Brissy. 240VAC for Aussie power points. As well as fixing magnetised watches, they are useful for demagnetizing tools, oilers, the plate in your skull, the list is literally endless. http://www.labanda.com.au/Watch-Jewellery-Tools-g2/Tools-Testers-s16/page1.html
I agree on getting good one but I was thinking what is there to loose $10 ? that was ok with me and it did work for me so I just saved $85
Believe me I am all for buying quality tools, but I suspect the only difference between those is the label on the front and $85, so I think you made the right choice. They are all made in the same factory and of course the $10 unit works with both 110 and 220 V. I have seen many reports from people who have bought the $10 unit and had great success with it. Remember as a watch owner, this is an occasional use item so there's no need to spend a lot on it. I use mine many times every day, so I spent the money to get a nice Grobet unit, but for watch owners and hobbyists it's really not needed. Cheers, Al
