Hi, so I recently got a seiko 5 snk809 and it was working fine, I then decided to regulate it as it was losing about 1 minute a day. After I regulated it it was working fine then stopped so I shook it to wind it up and then it started working. After 5 minutes it stopped again so I wound it up and it would work but then stop after a couple of minutes. I checked to see if the watch was being winded and it was, so the watch had power but just wouldn't move, I dont know why this is, the watch has power but will only run for a minute or two when I shake it, this hasn't happened before to this watch, so if anyone could help that would be great. Thanks

Howdy, Well, this is my first effort of a watch repair. I have been fascinated with watches, clocks and all kinds of mechanical things since a young age. I decided at this time that working on watches would be a great hobby/interest to take up in my later years. I have already spent some time learning to refurbish and repair fishing reels in the last few years. So here is my first repair attempt. Interest in tinkering watches started when I dropped my Seiko SKX009KD diver to the tile floor in the bathroom. Was not too good an idea to put a watch on there with a towel thrown over it, pulled the towel and down comes the watch, face down on the tile floor. Needless to say, I picked it up and took a look, nothing seen. Then I shake it and hear a rattle. Not too good! So I did some research on the 7S26C movements. Read a lot of information and watched a lot of videos. Thanks to all that makes this information available. So I purchased a cheap watch tool kit from Amazon. I had other watches that needed batteries and some strap work anyway. I knew the kit would not be 'pro' grade, but it was a nice kit with all the basic tools needed. Back to the rattle, I figured the Oscillating Weight (OW) had become separated from the bearing. So I used the case back wrench in the kit and opened the back, and sure enough that was the problem. I looked on-line for a replacement OW but could not find any except one on Ebay for $35! So I decided, what the heck, I'll try to repair this one. So, here is what I did being a little mechanically inclined but never at this small a scale, I performed the following: 1) remove case back. 2) examine the OW, it was dislodged/loose from the bearing. 3) remove center OW bearing from center post. 4) place OW on a small anvil, then use a small pin punch from the kit as to carefully work the metal around the OW's hole as to make the bearing hole smaller. 6) After enough working with the punch, I took a smooth round stone and gently kept working the ID of the OW hole until it just would friction fit to the surface of the OW bearing. 7) carefully press fit the bearing into the OW, I knew too much pressure would ruin the small bearing races and ball bearings. 8) finalized fitting of the bearing to the OW by applying a very small amount of red Locktite thread locker using the end of a pin as an 'oiler'. 9) I then let the OW set for a day to cure the Locktite 10) install OW per alignment instructions in the 7S26C technical guide. At this time I also wound the mainspring up 8 turns to check the power, it ran for about 40 hours. 11) did not have any watch oil, so I used a very small amount of some 10W synthetic engine oil using a small pin as the oiler to lubricate the OW bearing ONLY. It appears to be a successful repair for now, watch been running great and keeping good time for about 2 months. I'm sure something else might have gotten damaged during the fall, especially the balance assembly, but then again the watch is working fine for now. I might use this particular watch to dive deeper into the 7S26 movement at a later time. Kind of happy for now. Got 2 other watches running with new batteries, fitted some straps and having fun with my new hobby. Look forward to learning some more. Now to find a 'bag o watches at a flea market and get busy. I know I'm going to need more and quality tools down the road, that's OK with me. Cheers, Chip ---

Hi all, i have no experience repairing watches but I am a pretty hands on and mechanical guy. I am looking for some advice for my Seiko SNZG15, 7s26 movement. It's a pretty cheap watch so I have a feeling it might not be worth taking to a professional to repair. I will explain what happened and I hope that someone here can offer some advice. I have worn the watch for three years straight. I was taking it off the other night and it slipped out of my hand and hit the floor face down. The Seiko emblem bent out from the face with the S still flush on the face and the o sticking out a bit, just enough to interfere with at least the hour hand. It's still ticking fine, but in my foolish curiosity I attempted to adjust the time. I don't remember which hand, but one of them came into contact with the emblem and got hung up. I was able to free it, but damage had already been done. Now I can't really adjust the time and the hour and minute hands are out of sink. When I turn the crown the hands don't move hardly at all, if any. I'm thinking that since it is still ticking and keeping time that the actual movement is okay, but maybe some gears related to adjusting the time are damaged. Any thoughts? Can you even get replacement parts for this movement? I have watched some of the videos on this movement and I think that if it were the gears under the calendar and date wheels I might be able to replace them and just remove the emblem. Thanks, Eric

I need to source a "Date Indicator Maintaining Plate" #0808-300 for a 7S26 "C" movement. I'm building a franken movement out of an "A" and "C" model and Seiko changed this plate. Any ideas as to sources? Thanks, RMD

At 7:34 in part 2 you were able to turn the gear train by turning the screw on the ratchet wheel. when I assembled up to that point the ratchet wheel wouldn’t budge but the gears can spin freely. Any suggestions?

Hello , I am from Houston. I have gotten in to modding watches particulary seiko skx007 , snk809. I'm not a professional I'm here to learn so I'm open to all suggestions. I will need help from time to time lol. BR, Haris

Hi There, I live in the UK and I'm learning how to service the Seiko 7s26 thanks to your Youtube Channel. I'm looking for parts so I thought I would join the talk to learn from others.

HI EVERYONE ...I had a Seiko5 SNZG15K1 ...I started playing around with the regulator and bought a timegraph 1000 ... anyways as I was moving the beat lever the hairspring stopped . I removed the spring , wheel and cock and the spring was a mess. I just want to know do these watches come ready to regulate or do you have to turn the brass stay bits on the end that hold the spring ..I think that the spring jumped on mine .but at the time I wasn't thinking straight and ran to disassemble it when I should of looked a bit closer back then ..Thanks Lenny...........

This is my first disassembly. The movement is a 7s26 from a Seiko 5 watch. It was running a few minutes at a time before disassembly. The oscillating weight was in two pieces. It appears the three pins(?) have all broken. My questions are: Can this be repaired? Is it as simple as pushing the broken pins out and replacement? What tool would I need to perform such a repair. I know I can replace the complete oscillating weight, but what fun would that be? Thanks for your time and knowledge,

Hi I saw the youtube about "Setting a watch in beat - watch repair regulating lessons"Great video. What I don't get is: How do I see the banking pins and the impulse jewel ? do I have to take some parts apart? Thanks
