SEIKO Hands Not running at Proportionate rate

[Chronopolitano]

Who else has seen this?
On some of my Seikos. the hour hand does not always land on every hour perfectly. On most, but not on all 12 of them.

When I use the crown to fast forward the hands, I noticed the following:

When the minute hand moves, the hour hand is occasionally not moving - for about the duration of 5 - 10 minutes - and then suddenly "jumps" as if to catch up.

So, for example, the time reads: 3:30, so the the hour hand points to 17.5, as it should.
But then, even when the minute hand is at 3:37, the hour hand has not moved at all - still pointing to 17.5

Then all of sudden, at 3:40. the hour hand jumps to be where it should be.

All this has the effect of the hour hand not always nailing the landing on every hour marker on the hour.

Why does this happen? Is this a Seiko problem? I have not seen this on any ETA movements.

Isn't this just play in the wheels? Is this a new or an old, not recently serviced watch?

Not sure - but they're new.

Oh, maybe I modded a few.
Did I screw up?

What did you mod? If you did not take the movements apart, or put a lot of strain on the hands, I cannot imagine that you caused this.

I forget which models - some SNZH, SRP, etc.
No, I did not mess with the movement. It was usually swapping only dials and hands.

But I have seen new Seikos also with this same problem, so I don't think it's just me doing all this.
Are the hands slipping on the post? If so, why?

[Martin]

If the hands were slipping on the post, they won't catch up. So it must be in the gears somewhere

Not seen this on ony of mine. Had three, but only one at the moment...

Ah so!
So then, maybe those eBay grey market Seikos that start bidding at $0,99 are factory rejects after all?
But that's weird too, since so many of those are also perfectly fine.

No pattern here.
Maybe they're all mixed in for all sorts of reasons..

I doubt whether rejects reach the market. Seiko would have better control than that.

[Seriously]
