EwatchpartsGenuine Compatible With Seiko (Sii) NH35/NH35A Automatic Watch Movement Date @3 White Brand

I use this "work horse" watch movement when building custom watches for folks on a limited budget. It never seems to miss a beat and doesn't require baby type handling when installing into a watch case. This is a robust movement from the start. And, it is very accurate if the time is taken to regulate its beat. If it had any drawbacks it would have to be the somewhat stiffness of the regulating levers. One has to be very careful not to slip and potentially damage the balance wheel while attempting to move the regulator arm. But once regulated, this movement can keep time with most swiss movements I have worked with...

Worked as expected shipped fast and great value!!!

I like this! It is holding up well and at least my copy is doing zero beat error and a +2 second. I was a little unsure on this unstamped movement, but everything checked out. I will say that it seemed top quality. Must be a bulk lot of movements that would normally be for building watches via a micro brand thing?

These movements are awesome. I bought two and put them both on the timegrapher to see how they came to me. One was -10 seconds a day with 0.1 beat error. The other was +4 seconds a day with no beat error. Buy confidently!Update: I was able to regulate one of the movements to dead perfect. Incredible value for this seiko movement.

No point in servicing these Seiko movements when you can just drop a new one in for such a low price. Well packaged and arrived quickly. I did change the rotor out for the original from my watch but that was it!

After a bit of research, found it was a pretty simple project to replace the NH25 movement that came in an Invicta dive watch I've had for several years but wouldn't keep wound with normal movement. In the process, I now also have manual wind capability. The movement comes with a long threaded stem in addition to the one shown in the photo. For my purpose, I trimmed the long stem, cleaned up the end of the threads, and screwed the crown from the original watch onto it. It still screws down onto the case to improve watertightness. Doubt it's still good to 300 meters, but then neither am I.

Ordered 4 of these movements, 3 I was able to time out correctly, but 1 was so far out of beat that I couldn't time out via my timegraph. Expect this when buying lower prices items.

I haven't installed this movement yet, or put it on the timegrapher. I will say that I recieved this movement 1 week earlier than expected. So that is a huge plus!I haven't decided if I will replace the entire movement or scavange the balance wheel assembly to replace the one I inadvertently damaged. If I use the entire unit I will update this review. Either way I'm happy.
