Hi Gary Nothing specific on the 1406U but have the 1407 1405, and according to Ranfft its close in design to the Zenith 135 so I popped that one on too. There are manual watch winders out there they are like a small spring loaded clamp I have attached images. They come in different sizes to fit the crowns. cheers
Hi, yes it is a 718 movement. Never come across this problem before. The watch is keeping great time but every day the date change changes an hour forward so one day will change at say 1am, the next 2am and so forth
Just so I understand clearly first it's an hour off then you reposition the hands it's one half hour off?
As it's the calendar parts shall have to take the hands and dial off and see what's going on.
Then it's hard to go beyond this because which movement is this? But we could guess if the hands are actually tracking it's probably not a Canon opinion the problem perhaps. That takes us back to something to do with the the calendar parts which are under the dial unfortunately. Then we can't even look for a tech sheet if one even exists without a movement identification. But more likely have the watch hasn't been serviced in a long time that needs to be done.
Just in case your part doesn't work the last link has one. Big part of the problem might be for people identify the watch perhaps. It actually goes by several different names. Then as far as I can tell from looking at bestfit online and the Site below there's only one set bridge.
I snipped some images out of the physical bestfit book at one time there was what was called the fingerprint system used to setting parts to identify your watch. In this case will use it to see what your parts are supposed to look like. Unfortunately the snipped images won't print out the correct size but at least you can look at the shape and see if it matches..
The second link has a listing of all the parts. The third listing which watches have your set bridge and its and the last listing in case you want to buy one it looks like they have it in stock.
