Quartz strikes again 🙂  So, a brand new Seiko 6G28 came with a dead battery from the store. Tested the battery, completely depleted, but not leaked. Replaced the battery with a brand new Renata 377, and it’s not moving. I can hear the stepper clicking about once every 2 seconds. Tried with brand new, just ordered Varta 377, same thing. I tried tapping the movement, the case, tried setting the hands forwards and backwards with the crown, but still it does not move. I’m looking at the manual, I don’t see any reset procedure. The battery seems to be the correct alternative to 626SW. Any ideas why a brand new watch won’t start ?

Hi give it a little jump with the line release tool, (cheap enough on eBay). It may be Down to sticky oil and being dimmed up. Thr line release tool will spin the mechanism round slowley a n free the train. Do this without the battery in then re fit battery and try again. It sometimes helps if you put a little oil or spirit in the train pivots before hand..   if it all starts up ok , that’s good but be aware the movement will needs a clean and oil.   Service.

Haven’t found anywhere to short + with -, and it’s also not in the manual for 6G28 battery replacement

Thank you, Sir, following your advice and looking at line release tools, I found some people having luck with using a demagnetizer. So I did, with the battery out, I put the back of the watch on the demagnetizer and pushed the button, and this started to move fast the seconds hand in a “jiggly way” and other hands started to advance. Then I run it again while pulling it away, to demagnetize it. Put the battery in, and now it works fine.

 

Thank you !

Shorted the battery? + to -. Is that required?

Typically on a street quartz watch with no complications reset is not required. Then hopefully M not reading that the way I am which is shorting the positive the minus which is shorting the battery out which is not recommended on watch batteries as they just don't have enough power to withstand.

The problem with brand-new watches are there brand-new to you but how long has it been sitting in the store the warehouse the factory etc. if the battery is dead well it's been several years and it also depends upon temperatures like it was a jewelry store under bright lights getting nice and toasty warm for several years that would be a bad thing for the battery and lubrication

But this is a brand new watch, bought by a friend of mine from Joma

Sounds like no warranty issue except you already opened up the watch. Companies usually get nervous about warranty issues if others have been playing with the watch.

Seems it can be somewhat serviced.

Interesting wording of somewhat serviced? That is a standard Seiko service guide implies that it can be serviced. But it's still a brand-new watch covered by some sort of warranty I would go that route first. Then maybe don't want to service the watch may be the just replace the movement

      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....
