First part of the disassembly, fixing and reassembly of my new Seiko 7T32-7C20 Flightmaster Chronograph that  recently bought as defect.

 

The damage was caused by trying to manually setting the date at around 11:30PM, when the watch usually starts to change the date automatically.

 

Enjoy the first part of the video.

Excelllent, I am really enjoying this. Thanks for providing such a useful guide. I can't wait to see how it progresses.

I am uploading the second part, it is taking the whole day thanks to my crappy upload speeds (almost 4Gb on max 1MB upload... make your calculations on how much it takes...), and I will post the link as soon as it is done.

That's a really nice looking watch! Jealous [emoji4] [emoji16]

I seem to be buying nice watches that need work but can never work up the nerve to open them up.

I've got 2 x 7s36 , 1 x 7t34 and 2 x miyota 3u62 that are vying for attention.

My main problem is i don't have a permanent workstation. Do you?

Hell, if the video is 4Gig I would use half my monthly bandwidth allowance just to watch it, may pay to process the videos  through compression software.

Just adjust the resolution that you want from the cog wheel and let YT do the rest.

Fantastic work. I am not envy .Have a 7T34 that i should dig into someday next week . And a Y187 that has a problem with a contact . But all the plastic. Ujk:)

Yeah. When I saw what was inside my 7t34 I immediately closed it up again. Also a ym62 that keeps stopping. Edited by ro63rto

And finally, the third and last part of this series of videos... Pointing out how I repair the movement replacing the date driving wheel and how I repair the hour wheel, instead of replacing it.

 

Have fun!

 

Another great vid George by following your vid I have also successfully serviced/repaired a 7T32.PS when you strip how do you store the parts because I found the magnetising of parts from the stepping motors a problem.

Hi CB, my take on it, or the way I do, I stick the motors to a piece of rodico and carefully find a separate container (maybe a compartment parts tray with lid) to store them and the other electronics (non washable) parts...each in its own compartment. Then I clean all the other parts accordingly. I don't worry much about magnetism since eventually they will all be exposed from the natural working on the watch. Some people demagnetize the parts they wash but I find it an iffy thing with the equipment at hand.

 

 

George, excellent videos, I have not words to thank you enough since I haven't yet worked on this movement but have one waiting for treatment! Big thanks to you for a wonderful job and post.

 

Cheers,

 

Bob

I also use some rodico. I never put the rotors in the washing machine, I just clean them with the rodico very carefully. As per where I store jem: I have a small compartment plastic box with lids: a small piece of rodico keeps them safe from broking if it falls on the ground.

      Down the rabbit hole!

      By fnick · Posted

      Hi all Thought I'd show my small and trying to keep under control watch collection! Apart from the Enicar all were under £12! At least if I destroy them in the process then I won't be too worse off. A few pics to start off with First of all my first attempt. A Thuya pocket watch. It was only running face down and would stop when vertical. So now it still works face down and only slows down when vertical so at least an improvement! 😄  I only have a generic watch oil at the mo so that won't help but I'm hoping to get some more appropriate oils in a couple of months for my birthday. I did have to get a crystal for it since it didn't come with one. It didn't look as though it would friction fit (and I don't have a crystal press in any case) so I glued it to the case with PVA. So far so good. Next up above are a sekonda and citizen automatic. Both non runners. Both with broken balance wheels amongst other things. I'm hopeful the citizen will start when I get the new one I ordered but the sekonda is being kept for spares and trial of new techniques. And finally the Enicar and the timemaster. Both running when I got them. I wanted to get running watches so that at least I stood a fighting chance of still having a running watch after the service! It was all going well on the Enicar until I dropped the balance wheel during reassembly...😔. Unfortunately they are quite expensive to get so for now I'll won't do anything with it but I would like to fix it at one point. The timemaster is still running (yeah!) but I managed to break a dial foot during the deassembly. First repair attempt failed so now I am looking at soldering it back on... So there we go. My initial foray into this great hobby. Thanks for sticking with this tale so far.  I'm hoping that once the balance wheel arrives for the citizen I will be able to say I bought a non runner and fixed it! So fingers crossed. Thanks for looking, Nick

      Like losing Ranfft. That was a wake up call. We took his website for granted. Miss him terribly.

      Its 4 o'clock in the morning here in the Uk, i cant sleep, i dont sleep, not much ever really. My brain never shuts off to rest, I'm just a constant thinker, i have to be very tired to be able to sleep,  i guess eventually it will be my undoing and my health will suffer because of it I'm sure. But while I'm here i want to get as much out of life as i can, and give as much as i can, to help,maybe to make a difference to someone's life if that is within my capability,recent events have made that need even more clear to me. I'm not sure where I'm going with this or why i bring it up , or if its relevant to want i want to talk about its just in my head right now. What i do want to talk about is something thats been on my mind for ages. I like to be prepared,  I'm not fond of surprises because surprises take control away and i am a bit of a control freak at times. This forum, Our Forum if i can call it that, is here because of two reasons. The guy that created it and keeps it funded and the people that joined it.  Without either, it would not exist, and lets face it one day it won't ( I'm a realist and i talk about things others dont or who are afraid to in other words folk that dont particularly prepare for the inevitable). How many of us visit here regularly ?  How many among us almost depend on the forum as a way of socialising because they are stuck at home and how many of us has it become part of a daily routine to check in and see if they can offer advice or get help with something they are working on or just to have a chat and engage in some banter. The members here are in the thousands and thousands have disappeared over the years many had just a fleeting visit. But there are a good few of us that know each other quite well and visit regularly. I dont know about you but i wouldnt want to lose that communication with you all, in all honesty it has become an important part of that side of my life and helps to feed my passion for all things watches. Some of you may think differently and thats ok, some of may stop and think # what would i do " Without Our Forum " #

      Gamblin Gamsol for cleaning?

      Naptha appears to be a general name and its content can be varied depending upon what it's specific use is. Lighter fluid as an example can be light or heavier also with other ingredients to help it burn. Try sesrching for benzine ( as opposed to benzene which is linked to causing health issues ) . There are other fluids such as ethanol that you could try and also methylated sprirts, mostly ethanol with a small percentage of methanol added. Experiment with any new chemical to see how quickly schellac dissolves in its presence. I have tried a few things but hexane is not one of them, i understand it does evaporate very quickly.  Be sure sure to check out any safety data on chemicals you try. Toxicity of fumes and flash point information, ultrasonic machines can heat up fluids even without a heater function. And of course always ask here for personal opinions when trying a new substance.

      What tools does ebay have to offer this week.

      By GuyMontag · Posted

      I have that set and really like it. I prefer that crystal holder over the one that came with my Bergeon claw tool and any time I use the claw I use this one instead of the Bergeon one, just an additional bonus with this tool.
