Seiko 5 rotor

[Seiko23]

Hi

i have a Seiko snz809, it is a week old and there is a rattle when it is moved up and down like the rotor is slightly loose, I’m just curious if this needs fixing or if it’s just how it is?

 

thanks

Some ball bearing are more lose than others. If the auto winding work fine, there is nothing to worry.

Unless  it is impacting  something  I would  let it be.

Hi The question is how loud is the noise, If its grating  it needs looking at if its just a swishing noise and everything is working as it should leave it alone. From where did you purchase it and is it new as in it has a warranty ?.

Had the same issue on an Invicta (It has the Seiko NH35 movement). Rattled and didn’t sound smooth. Also the watch stopped occasionally through the day. I could see through the clear case back the rotor was moving but it was obvious in certain wrist positions it wasn’t smooth. When I removed the case back to check what was happening, the rotor fell out! The screw obviously worked itself loose. Refitted it and it’s been fine ever since. Two minute job.

That is when it's a loose screw.

Even when it's not some owners, often new to mechanical watches, are bothered by noise that the balls bearing sometime makes.

I just installed an NH38 (time only version of the NH35) into an older Seiko watch. It rattles a bit, but no more than it did before, and a lot of it is the bracelet. It's not an especially quiet movement. If you've ever worked on anything with the "magic lever" automatic works, it's a chatty little guy. I have a 2824-2 on at the same time (experimenting with regulation), and it's noticeably quieter in comparison.

If its a week old then the bearing should still be ok. I've come across watches where the screw holding the rotor came loose and caused the rattle. Is yours a display back? If yes, you may be able to see if the screw is loose thru the caseback.. its the one right in the middle.

These Seiko do have a noise when shaking but only if you shake it so that the automatic weight moves...(that causes the noise). If you bought it new from a shop then go back and ask to compare with another similar one.... If you bought it online and it came from Asia ........  good luck as anything could be in that case.

"There is a rattle when it is moved up and down like the rotor is slightly loose" 

I told him what I did to fix my NH35 equipped watch with the exact same symptoms.
