Hello Everyone,

I recently bought myself a cheap repair kit and I successfully changed the battery on this watch that was dormant in a drawer for about 4 years!

However, the problem is I haven't done something right as the day sub dial is ticking away same as the second hand sub dial!, I'm sure it isn't meant to do that.

I'm obviously putting it back together incorrectly and also the two little white plastic cogs you can see in the pics, I can't remember where they go?! If someone please can talk me through the process it would be massively appreciated or any pointers, advice would be great. Thank you

Hi  The movement id (miyota 6U70) is that correct? .  I am not able to find the tech sheet for this movement but have attached one of a close relative in the hope that it may provide you with a little help.  The errant gears will have some  significance with you problen.

Hi Having trouble locating a tech sheet on the plate which is removed there will be a number  such as 2N50  or  1L12y or somthing like that . the number on the movement BU70 or 6U70 turns up nothing .   If you could post the number off the loose back plate we may be able to locate somthing,

Please disclose the caliber, so the relevent datasheet and a schematic diagram can be searched for. Once your post leaves the recent topics billboard, it will take another activity on your thread to get your post on the board again, so updates or new pictures become a useful tool to get on the board and that is where responses to you gets prompted. If no luck finding the caliber,you can post a topic to help identify the movement. Keep us posted on your progress please.

Hello I can't seem to locate the plate's tech sheet. It doesn't seem like the numbers 2N50 or 1L12y produce anything. Additionally useless is the movement number BU70 or 6U70. We could find the information we need if someone could provide us the number from the loose rear plate.

    • Hi guys. @VWatchie Those images are self hosted (not hosted on this server). Do a look at the page source and you will see this. I’m afraid, I can’t have control or backup images not hosted on this server. ( They seem to be served from here: https://qehvsw.bn.files.1drv.com/) This server is backed up fully every night and the database is backed up and versioned every hour, all stored off site on Amazon S1 platform. It’s hard for us to lose data. Ive got a huge overhead of space on this particular server the site is served from so no worries there 🙂 Sorry all for lack of response so far, I have been extremely busy and am embarrassed to say that priorities had to be set in place for a while.  Be assured that i’ve got constant monitoring and alerts should the site be in an extended problematic state (down etc) and work on these issues if they arise.
    • Web sites are cheap. Message board are easy. Hosting both is less than 100 usd a year and small advertising would cover most of that.  In the discord group we did some 15 min poc and threw up a couple of different message boards on a domain i host.   The real value is the data / information / hive mind While I'm a rank amateur in watch repair the information and assistance on this board is invaluable. The members on here are friendly, entertaining and a wealth of knowledge This is what needs to be preserved  --Jeff

    • HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....
