chrislovessushi 0 Posted March 19, 2018 I recently acquired a Noob V7 that has undergone some mods already. The watch seems to be running great, however, a gen datewheel was installed and apparently ever since then the date skips a day. So if the date is set to the 18th then tomorrow the watch will say it’s the 20th. The seller informed me of this prior to purchase and stated that it should be an easy fix and should get fixed during a routine servicing. Anyone have any thoughts on this? I’m comfortable with basic things like swapping out movements but I’m open to trying some basic movement disassembly if you guys think it will be a relatively simple issue to correct.

tabuktime 52 Posted March 19, 2018 Can you set the date manually to those that are normally skipped? Share this post Link to post Share on other sites

Setting the date is no trouble, when flipping through dates manually they flip to the next day quickly and snap perfectly into place. Share this post Link to post Share on other sites

Nikosaldente 630 Posted March 19, 2018 I think that I'll give a shout @GenTLe to chime in! Wait a few hours, I'm sure he'll have an answer! You'll probably need to remove the hands and dial to access the date spring/gear and see what is going on! Cheers! Share this post Link to post Share on other sites

Rx4Time 1,472 Posted March 19, 2018 Is it an A3135 ( decorated 2836) or SA? I assume SA because of the gen date wheel. Share this post Link to post Share on other sites

Sorry mate but not for this, never put my hands on any SA/SH movement whatsoever :( But really it is strange the behavior of the movement... What happens the days after the 1st one of date setting? Does the watch change always 2 days? And what happens when the time is advanced 24h from the crown? Share this post Link to post Share on other sites

It is not strange because the 2 parts are completely separated (quick set from the standard date advance with time). What I find strange is the 2 day advance at all...

Rx4Time 1,472 Posted March 20, 2018 The SA3135 does have some known issues which can occur with date change. The ideal fix is to swap in a few gen parts to fix this. I'll have to review which are the necessary changes. Where are you located? I can suggest a couple of good people depending on your location. Share this post Link to post Share on other sites

I’m in the southeastern US. I spoke with Katt before I posted this but he said he’d need to take a look before he could say anything. I just spent close to $1k on the watch (it has some other aesthetic gen additions) so I was hoping to not have to spend hundreds more on it just yet.

If I advance 24h from the crown, the date rolls over to the next day as it should. The date also properly advances 1 day when I use the quick set function. But when left alone, at midnight the date advances by 2 days. Does that make any sense to anyone? Share this post Link to post Share on other sites
GenTLe 1,485 Posted March 20, 2018 Looking how it works the date changer in a 3135: http://forums.watchuseek.com/f20/date-change-mechanisms-how-they-work-760001.html and and finally: Probably what to look for is the date changing wheel or the spring that push the lever that works on the cam below the date changing wheel. But as Katt wrote you, it needs to be disassembled and checked. Share this post Link to post Share on other sites

Misiekped 0 Posted March 21, 2018 When is done via quick set thre is no spring involve, only the jumper spring #614 which is really stopper for the date not to advance to many days During normal time the date wheel mounted #623 + 625 jumps the disc using a spring and if your 614 is weak then it may advance 2days That was common issue with early yuki 3135 Replacing 614, 623 and 625 always fix the problem Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites

chrislovessushi 0 Posted March 21, 2018 Bummer. Looks like it’s going to be $200+ that I don’t have right now to fix. Feeling like a pretty sucker for buying a $1200 broken watch. Thanks for the replies everyone. Share this post Link to post Share on other sites
