Epanoui Posted December 14, 2006 Report Share Posted December 14, 2006 Well I finally got my noobmariner today and it seems to be having an issue. 1st, and this might be unrelated but I thought I'd mention it first just in case it is related, I noticed the crown is rather flimsy and really weird feeling. Almost like grinding metal, just really rough. When screwing it back again, it feels like it just catches on everything. And I noticed once, on the final turn of screwing it back in, the minute hand moved ?!? lol. So I had to unscrew it and set the time again. 2nd, and this is the main issue, my movement seems to stutter. The second hand specifically "skips" rather weirdly, but it always seems to catch back up with itself. I can't describe the problem very well in words, so I uploaded a video of it. It's a dark video but I think you can clearly see what happens, watch the whole thing. And also note that it doesn't matter where the minute and hour hands are, it happens everywhere around the clock, so I don't think it's getting hung up on those. LINK: Movie Link LINK: It's a large file, 27mb, so try right clicking and using "save target as" on windows or "download linked file" on mac. I've uploaded it to YouTube as well, the second link, and it's lower quality but I think you can still see the stuttering. Any help is appreciated! Cheers.

Highflyingclive Posted December 14, 2006 Report Share Posted December 14, 2006 A Rolex LV that I bought in a Chinese street-market had a stuttering second-hand. It didn't affect the timekeeping but it drove me crazy. So I gave it to my brother. I don't like him very much. Quote Link to comment Share on other sites More sharing options...
tvt Posted December 14, 2006 Report Share Posted December 14, 2006 That is most certainly NOT normal in any way! The second hand should have a nice smooth sweep. As far as screwing it in goes, well welcome to the world of reps. You often will find that things like screw down crowns simply lack the silky feel or quality you might hope for, but they generally function fine. Sounds like you have a bad movement and it should be replaced no questions by the dealer. Quote Link to comment Share on other sites More sharing options...
NRG Posted December 14, 2006 Report Share Posted December 14, 2006 Unfortunately stuttering second hands with the 21j Asian movement is normal, it's the nature of the design. The Zigmeister has posted about this before. Be slow and careful when operating the 21J, I broke a clutch return lever in the keyless works on my first noobmariner, you sort of have to ease the stem out with a back and forth jiggle for the keyless works to engage properly. I've serviced both of mine and they work much better but straight out of the box they are not so good. When screwing the crown back down I've found it best to press it down and screw it back wards until it sort of settles then screw it down properly. The grinding you feel is dirt/debris, when the threads are clean and oiled with stem grease it feels very smooth. Quote Link to comment Share on other sites More sharing options...
Epanoui Posted December 14, 2006 Author Report Share Posted December 14, 2006 Thanks for the replies guys! I talked with the dealer and he said he has heard of these symptoms before and will send me a new one after the new year. As it does still keep the time (I think) I'll still wear it and just try to ignore the stuttering. Also, as far as the crown, can I just put a droplet of oil on the screw? Or is that not how it's done? Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted December 14, 2006 Report Share Posted December 14, 2006 21j Asian movements beat at 21600bph; roughly 5.x ticks per second. So, the seconds hand does not 'sweep' smoothly. If you want a smoother sweep, a 28800bph ETA will do the trick... Quote Link to comment Share on other sites More sharing options...
NRG Posted December 14, 2006 Report Share Posted December 14, 2006 21j Asian movements beat at 21600bph; roughly 5.x ticks per second Exactly 6 times a second Ubi! Unless is knackered! Quote Link to comment Share on other sites More sharing options...
tvt Posted December 14, 2006 Report Share Posted December 14, 2006 Guys, watch the viedeo, he is not talking about a rough sweep, he is tralking about some crazy stuttering effect where the second hand stops for a second or two and then jumps forward again. I have never had this on ANY watch (even cheap asian movements) and I certainly would not call it normal or acceptable. In may not be uncommon as those Asian movements are low end, but I sure would not accept it. I'm glad to hear the dealer will correct it.

swdivad Posted December 14, 2006 Report Share Posted December 14, 2006 My swiss 7750 does that, but not as pronounced! That's a major stutter you have there. Quote Link to comment Share on other sites More sharing options...

No. Quote Link to comment Share on other sites More sharing options...
cls Posted December 14, 2006 Report Share Posted December 14, 2006 Looks like a symptom of the second hand slipping. The hand itself is just not tight enough on its pinion. Alternatively, the wheel may have been pressed down when setting the hands and the gears are not making good contact. Hooray for TZ watch school.!

2005SUBMARINER Posted December 14, 2006 Report Share Posted December 14, 2006 the original miyota 8215 movement japan is very choppy ! so acpect those asian reps to be a lil choppy . if you want a smooth sweep like UBI said spring a few extra $$$ & go ETA Quote Link to comment Share on other sites More sharing options...
Pugwash Posted December 14, 2006 Report Share Posted December 14, 2006 To everyone recommending an ETA as a fix, please watch the video. Quote Link to comment Share on other sites More sharing options...

RWG Technical Posted December 15, 2006 Report Share Posted December 15, 2006 If it's asian movement they all have indirect center seconds drive, stuttering is normal and varies between models, doesn't affect timekeeping and cant' be fixed. It's just the way it is with any indirect drive center seconds movement... RG Quote Link to comment Share on other sites More sharing options...
NRG Posted December 15, 2006 Report Share Posted December 15, 2006 Yeah, but this one is not well The Zigmeister, its jumping more than stuttering... Quote Link to comment Share on other sites More sharing options...
crystalcranium Posted December 15, 2006 Report Share Posted December 15, 2006 Yeah, but this one is not well Ziggy, its jumping more than stuttering... Agreed, I had a "stuttering" 21j that kept great time but could give you a seizure if you looked at it for too long. This one looks nothing like the problem I had. It is more jumping than stuttering as you said. Quote Link to comment Share on other sites More sharing options...
RWG Technical Posted December 15, 2006 Report Share Posted December 15, 2006 Yeah, but this one is not well Ziggy, its jumping more than stuttering... I didn't see the video, so it must have some other problem other than the normal jumpiness... RG Quote Link to comment Share on other sites More sharing options...
Devedander Posted December 15, 2006 Report Share Posted December 15, 2006 I would definitely look at the video... it seriously looks messed up, like the seconds hand is possessed or something.. Quote Link to comment Share on other sites More sharing options...
