      Today I show off what is probably the most accurate Seiko NH35 in existence.
      Let's see what this brand spankin' new Invicta does on the timegrapher:

      Oof. Ya hate ta see it. I know these numbers aren't anything to cry over for an 80 dollar automatic, but considering how these days microbrands stick this movement in watches costing hundreds more, and Seiko themselves with the equivalent 4R in watches costing even more, it's just not great. The rate itself to me is a trivial matter as nudging on the regulator is a trivial task. But what speaks to the quality of a movement in my eyes is the consistency of that rate in different positions. With 12 seconds per day difference across positions, middling amplitude, and fluctuating rate while static, albeit slight, is all just a bit "meh" to me. 
      Let's crack it open and see what we can do.
      .
      Hairspring seems to be pulling towards stud.

      Hairspring removed from balance and mounted on cock and we can see the full extent of the malformity. That collet is a good ways off from the jewel.
      Few hours of sweat later:

      Much better! Regulator now runs the full length of the terminal curve without disturbance and collet is centered on jewel.
      Let's check out what else I saw:

      Some places are absolutely flooded.

      While others just barely got any. A good thing I intervened. This thing needed to be redone top to bottom.

      Stripped apart, ready to get rid of the crappy factory lube job, and get a real, proper lube job.
      All put together, lubed, and few rounds of dynamic poising later:

      Massive boost in amplitude,  runs on rails and a measly 1 second difference across all positions. Wasn't lying when I said "probably the most accurate Seiko NH35 in existence." See for yourself.
      Isn't it at the moment a bit of a waste that this souped up NH35 is being trapped inside its Invicta skin? What do you think?

      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

      I have a seiko 7548-700f that I bought at a flea market for 15 dollars. Very beat up. Heavy scratches on the back near the lugs. Looks like the previous owner didn't know how to take a case back off properly. Last year during a battery change the screwdriver slipped and i hit the coil block. I managed to replace it without trouble. Starting a couple of months ago it started losing time. LOTS of time. I would take it off overnight and in the morning it would be 5 hours behind the correct time. Happens no matter what position the watch is in. I suspect that this is because the hole for the center wheel is not circular anymore. I know this means I need a service but I can not afford one. I am in highschool with no job. I have posted similar threads to this on several different sites, but no one is helpful. They tell me to get a job or to just pay to service it. What should I do? Should I learn to service it myself or is it even worth it?

      I'm about to start working on a Seiko 6602 and would like to be able to put it on the timegrapher before and after and see how well it works but i'm struggling to identify the correct lift angle for it.  It seems to be missing from all the general lift angle lists I've come across.  I've read in other posts that most Seiko's are either 52 / 54.5 but which is it for this movement, can anyone help please?

      Hello All.
      I'm a fellow watch enthusiast from the North-East of England. I hope everyone is keeping well.
      I recently bought myself a cheap watch repair kit, dusted off the old watch storage box and started to giving my watches the attention they required, it's been going quite well so far but do need some guidance with the correct steps of putting the workings and the case back on for my Accurist GMT Grand Complication, hopefully I will do a separate post on this with pics.
      Anyway hope everyone is having a decent Friday night.

    • The hairspring looks ok in the first photo you posted.  It that is concerning if the regulator causes excessive change when only moved very slightly. Better quality movements have longer hairsprings generally, which permits finer regulation. These hairsprings are reasonably long.    If you really wanted to, you could mount the hairspring alone on the cock and check that it looks right in terms of alignment with the jewel hole. Getting the terminal radius corrected can be tricky, but yours at least looks consistent.    In terms of your timing variations, the effect is being exacerbated by lack of amplitude. Don’t let this allow you to jump to the conclusion that the balance is out of poise. Get the amplitude up and see where you get to. I think your pendant positions are possibly showing excessive drop in amplitude. Given that this movement has been mucked about with previously, check the balance pivots aren’t bent, even though it has an antishock setting. 
    • I think that maybe because I tripped it off the lifting arm because i'd taken the hands off to remove the dial.
    • Here we go with another possible lot of 15 comprising.  SEIKO Ruby De LuxeOlma SportForlisMovadoRotaryBintimaCitizenParaNelsonUnitasRoamerTip TopAncre GoupillesTitan   Anything here worth repairing with a view to keeping or flipping?   I get a watchmaker to sort out most of my purchases. If its just a battery issue, strap or general clean I can do that, but I'm not up to the delicate repairs yet    
    • Hello all, My Name is Eugene and I am a watchmaker located in Atlanta, Georgia . I was full time software engineer and  part time watchmaker since 2000. in 2019 I quit my day job  and now my wife and me full time servicing watches. Dream come true!    
    • @JohnR725 @rodabod Stripped, cleaned, and lubricated again. When I originally got it, there was a small kink in the spring near the regulator, which I was able to decently fix I think. I examined it again today, and it looks like the terminal curve might be off, which I imagine is what is causing such significant timing changes when I try to regulate. A hair adjustment will easily make a 30 second change, but I dont know if that is normal or not. Photos attached. Dial Down: +1  254°  0.2 Dual Up: -7 236 ° 0.2 Pendant Right: -24 184° .1 Pendant Left: -31 194° 0.0 Pendant Up: -46 183° 0.2 Pendant Down: -23 191° 0.0 Dial Up again after: -3 238° 0.0 Time grapher at 44° and averaging on 20 seconds.
