Another great thing about the automatics with handwinding feature is that you dont have to worry about the overwinding. If a full charge needs, lets say, 40 turns of the crown and you give them 50 you wont break anything cos when fully charge the winding mechanism disconects.
A great movement... Pagani Design seem to be using this in the majority of their watches now.. Even the 7S26 was a great movement.. ..and my dad's seiko watch is still going strong to date since December 1999 without service. That's 23 years and 6 months to date with ongoing accuracy....without a service needed
To me this movement is one of the greatest ever. Very robust and reliable. I got a unicorn running +/- 1 sec a day, but my other two running about 10-12 and other 35. Shows you how wide the range is so I need to regulate it myself. At least its very precise!
Thank you so much for this informative video on the Seiko movement. I've read about several micro-brands and homage watches being equipped with this movement, and had wondered about the quality of the movement. Of course the "Seiko" name alone speaks volumes in and of itself.
My San Martin Ranger 36mm has the NH35 in it and is running at + 0.2 seconds a day out of the box. Great movement that's affordable and easy to work on. No negatives here!
I have had a Steeldive SD1969 with an NH35 for 18 months. With a little effort I managed to regulate the movement to 0 beat error and +2 sec per day. The amplitude of the movement is on the low side but this does not seem to have an obvious negative effect. The watch runs fastest with the movement upside down (watch face down). Should your watch run a little slow over the course of 24 hours, place it face down during the night and see if it catches up.
"Should your watch run a little slow over the course of 24 hours, place it face down during the night and see if it catches up" Interesting! I might try that! Thanks!
@@sumahama1981 That works for my watch that has an NH35. I have no idea if that's consistent behavior among all NH35 movements. However, you should be able to find a position in which your watch runs faster or slower than in does in any other position and you can use that property to your advantage.
The movement is a stunner. With care and an ability to move the regulator in hair's width increments, the accuracy can be brought down to within the Swiss qualification for a chronometer (-4 to +6 secs a day). My example is in a military watch and is around +3 seconds a day. This is better than some quartz movements. Quite how they cram all that synchronisation into such a small package is genius.
It is no better but still impressive for mechanical movement in this price range. None of mechanical movements can come close to quartz accuracy, especially if you want to use mechanical movement outside laboratory. The worst quartz movements have max deviation 1 second per day, no matter of its position or temperature. Even Rolex can't do it. My cheap (~20$) Casio F-91W has +2 /+3 seconds of deviation... per month.
Im relieved to hear that adjusting the day/date at the wrong time doesn't necessarily damage this movement. "Foolproof" sounds nice but there still is a warning. They were keen to say it "may damage" in the manual so probably okay if you slip up.
I had an omega seamaster 300 brand new the date stopped working. Maybe someone at the store changed the date at the wrong time in the evening. Nevertheless the warranty covered it and I was without the watch for 3 months. Never had a seiko break on me. The omega is a $6000 Watch.
@@SillyVintageWatcheshi sir. Can U explain the NH34 movement?. Too many GMT watches at the market use this movement. I need to know. ❤ Is it good to use around 4/6 years above without any service?
What about the pretty low amplitude of this Seiko movement. Personnally, I was unlucky with a 4R36 inside a King turtle. Even with a big watch price tag, the movement was unreliable. The regulation was not bad, but the amplitude was around 230° on the timegrapher with a new movement fully wind and the good 53° lift angle set, seem not good even for Seiko movement. The deviation was big when I was walking, but good for an office day.
Can I get some opinions on whether or not it’s perfectly safe to wind (even daily) an automatic watch? Personally I LOVE the connection to the watch that hand winding gives, but I obviously don’t want to put undo wear and tear on my watch either.
If you look at the balance wheel you can't see it moving. The engineering is that precise. But, when I look at other movements even the Rolex 3135, ETA 2824-2 I see the balance wheel wobbling as if its off balance, like a spin top that is running out of 'steam'. I am no expert, but I'm sure a wobbling balance wheel isn't good in the long term. I have the Marathon 34mm General Purpose Field Mechanical watch with the NH35 in it. The watch, which come in EAT-F06 quartz and NH35 mechanical is issue to military personal. I was told by a miliary ordnance supplier the mechanical version is issued to covert operatives for its reliability; and for potential use in ATEX/ hazardous environment zones.
Great video, thank you for this. The issue that weirds me out about these movements, as they are put into watches, is this: ....why doesnt anyone set them right? I have two watches running each of these movements, one is -7 seconds per day, the other +26 seconds per day. It is literally amazing how accurate these watches are......and wrong. Im not a watch guy but if they can get the movement to run at precisely +26 seconds per day, for over two years, is it not possible to test this before they throw it out of the shop?
One week later after adjusting multiple times the speed of the 4R35 in my King Samurai (SRPE35K1), I've finally hit the "sweet spot", and now it runs with only between +-5 to 10 sec. per day! I highly recommend you do it yourself with your own wristwatch tools kit.
Crazy how many people actually care about precise time. I normally set my watches 1-5 minutes fast and know that I am generally going to be on time wherever I'm going.
I tried that back when I was in the world several times and it eventually drove me insane. Don’t know why but I’m the type who has to have my watch say the correct time. Of course I have to leave earlier. : )
True (to some degree). As far as I remember, two plastic wheels are used for the date mechanism. They are not relevant for the timekeeping part of the watch. In the date, they even make sense, since they don't require lubrication and are exposed to very little wear. I would also suspect that they are lighter than wheels made from metal, and therefore help with accuracy during date changes and help increase the power reserve. But that's my assumption.
I have six watches with this movement. Three seikos and three micro brands. You get more value from micro brands with sapphire crystal and over 100m water resistant. Unique designs with the same movement. Just do some research on the micro brands you are looking at.
I have Seiko Monster 2nd gen with 4r36 and there is some plastic part inside ( for date i believe). Can you explain why and how it affects other parts and the mechanism in general? Thanks

Hi, thanks for your comment! The SKX never came with the NH36 /4R36. It always came with the 7s26 and that never had hacking or hand-winding. But you can swap the 7s26 in your SKX for a NH36, I made a video about it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JzrTXkieUN8.html
Got a Zelos Hammerhead V3 with Seiko NH35 movement inside. All seems to work fine except i feel no resistance at all while hand winding the crown. The hand wind basically spins almost freely. Please advise if this is a problem or if this is how it winds ..
Indeed, the hand winding is very very light. You don't get much feedback, even if the watch is fully wound. If the watch runs out of power, does it start right up if you pick it up and start winding it?
@@SillyVintageWatches it doesn't work. I got it checked at a service centre and they confirmed a part broken in the movement. Zelos is sending me a replacement NH35 movement.
The way you ask, I would generally say yes. But the two movements are hard to compare to each other since they sort of belong to different price categories. To answer you more precisely: they both do well in their respective categories.
I own several Swiss watches with the SW-200 movements. They are solid and reliable except for one caveat, they are susceptible to overwinding. If they are overwound, there is a risk of shearing the teeth off of one of the gears.
According to watchcaliber the nh35 caliber are made in Japan or in Malaysia and is written on the rotor( it writes Japan or Malaysia close to the center of the rotor).Most of the nh35 that I have on my watches doesn’t have that sign at the rotor (the same with that movement at the video)That means that they are clones that they are coming from china? What is going on? I’m confused if you have an answer I will appreciate it! Thanks
Hi! I have a Spinnaker that runs on an NH35 movement and I'm troubled by an issue. My watch runs wildly. Within 15 minutes, the time fluctuates (if that is the correct term) like it's getting delayed by 5 mins then it's going to advance by 5 mins. This keeps on happening within the span of 15 mins. There is even a time when it stops running while it's powered up and on my wrist.
I have exactly the same with a new NH34 movement. Also the amplitude is between 165 and 179 and the beat error is 1.1. I wonder what is wrong, but I suspect their quality control is also not fully up to par
Adjust the beat error as close to 0 as you can and then adjust the rate as close to +/- 0 sec per day as possible. Then see how many seconds per day you are off on average and correct for that. If you want to go crazy you can adjust in several positions and various temperatures and find a happy average that works for you. I can with a little effort regulate my watches usually to within 0 to +4 seconds. You do need a timegrapher, a dust-free room with clean air, and the tools to open and regulate the watch. You will also need a new case back seal and seal lubricant.
Seiko movements have a reputation of being watches that just keep going and going. However, I would service them about every 6-7 years or as soon as you recognize a change in performance. With cheaper models that utilize cheaper movements, like the NH36 NH35 NH34 or NH38 you can get away with having them run longer and then replacing the entire movement altogether.
The problem would be that labor even without spare parts will far exceed the price of a new movement. An NH35 can be had for $35 to $50. The pallet jewels will certainly wear over the years. The oils used will become dirty and eventually increase wear on the pivots. An NH35 should be capable of running a decade without service or movement swap.
@@rosomak8244Well, unless you are hobby watchmaker capable of servicing and replacing wear parts, an NH35 is a throw-away movement because having it serviced will cost more than several new NH35 movements. Who is going to pay as much for an overhaul as he would for a new watch? An HH 35 is $40 retail price movement. How much is the wholesale price? As for degradation, yes, of course. But yeah NH35 movements can and often do run for over 10 years reasonably well without s service. It's also unlikely that a person will wear only watch all the time during that long a time period. What's acceptable as far as accuracy and pecsion go is an individual matter. The NH35 is a very simple movement. Something much more complex like a 7750 will usually need to have some parts replaced every 5 to 7 years or bad things will happen. I'm not saying you should not service an NH35. All I;m saying is it's not a fiscally reasonable endeavor for most people under normal circumstances. Yes, you don't thtoem out a a $1,000 movement because it needs a $600 service, but who will pay $200 to service a $40 movement?
The NH35/36 has a power reserve of about 41 hours. If the watch stops, it's usually good to give it a couple of turns by hand. The automatic winding takes a couple of hours of movement to fully wind the watch to its full power reserve. If the watch is not worn for long enough during the day or is not moved enough, it can not recharge itself on a daily basis and might stop at some point. If the watch is older than 5-6 years, it might also be due for a service, depending on its condition.
Most days I'm pretty sedentary (like on the computer or reading or watching TV) and the problem I've had with the 7s26 is that the automatic function isn't efficient enough to keep it wound. Does the NH36 share that same automatic mechanism?
