bluemax Posted February 7, 2010 Report Share Posted February 7, 2010 (edited) Hi, I just got UN Blue Surf with Asian 23J automatic movement. If I wind it manually, the watch works fine, but it does not wind automatically at all. The rotor just spins without resistance in both directions. The wheel connected to the rotor spins together with it. Power reserve dial fills up when manually winding, but drains (slowly, as expected) even when I wear the watch for the whole day. Hand winding the watch does not make the rotor spin, so I guess the click spring is ok. Also, I have noticed that the watch does not hack when the crown is in time setting position, and it is not possible to move the crown to switch from date to time setting, and vice versa. Instead, I have to go to the winding position and then to one of the others (did not try to move anything with force). Does something like this looks like it might have a simple fix, or some parts could be broken? Many thanks. EDIT: added an image to describe the problem better: Wheel 1 turns together with the rotor in both directions. Wheel 2 turns only when manually winding (I do not know if it is supposed to turn with the rotor or not) Could not notice any movement of wheel 3 when I move the watch so the rotor turns.

RWG Technical Posted February 7, 2010 Report Share Posted February 7, 2010 I wouldn't waste any time or energy trying to fix or understand the movement. Your best value, is to replace the movement with a genuine Miyota 8215, normally the Miyota is direct fit, or needs only slight modifications to fit.

Toadtorrent Posted February 7, 2010 Report Share Posted February 7, 2010 Hey Zig...this one is a tricky one as it is the Ulysse Nardin with the running seconds at 6, power reserve at 12 and date at 6. I'm trying to find the source for the original asian replacement movement. Of course the decorated rotor would have to be replaced...so I don't think because of the complications, that the 8215 will work. This is why I haven't bought one of these UN's yet.

Understood, that would explain why it's broken, with that many mods to any movement, it's a time bomb... Quote Link to comment Share on other sites More sharing options...

Yeah...I'm trying to find out some info on this movement. This is actually the first post on this that I've seen somebody have problems on it. I'm thinking it might be a movement I remember seeing in one of my catalogues that was modded in the same way as the other ones...stay tuned...I'll keep you posted.

FxrAndy Posted February 27, 2010 Report Share Posted February 27, 2010 Does this movement use an auto winding system similar to some seikos with toothes levers to push and pull on the crown wheel also like a pelaton system? Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted February 27, 2010 Report Share Posted February 27, 2010 Just found some pics of the seiko version, it is quite simple i would be interested to see some good photos of the non working movement Seiko As you can see here the rotors turns and pointer a mover round as the rotor does, this is slightly off set with as it moves pulls or pushes the pawl that turns the crown wheel and winds the movement, the difference here with the pellaton system is that this only winds in one direction.

FxrAndy Posted February 27, 2010 Report Share Posted February 27, 2010 Can any one provide some good case back shots of one of these, with the crown pointing up then that should show the pawls Quote Link to comment Share on other sites More sharing options...

nakortheblue Posted March 1, 2010 Report Share Posted March 1, 2010 Can anyone tell me where the stem release is? Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted March 1, 2010 Report Share Posted March 1, 2010 Thanks that proves the type of winding system, can you see pawls on the photo that blue max posted, i think i can but cant be sure, As for the crown release is that a small push button about 2mm down from the stem that look like the most likely candidate but i am expecting one of these in the next week or so i will be able to say more then.

That was the first thing I tried but it did not seem to push down. I tried unscrewing the blue screws too. I think I went around and pushed everything that looked like a button while pulling the crown. Please let me know if you find out as my son drop the blue surf and this happened... This is a picture of the movement but with the rotor still on. Less reflection from the over-enthusiastic pearlage. Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted March 2, 2010 Report Share Posted March 2, 2010 I will have a look at soon as i get mine from sixx Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted March 16, 2010 Report Share Posted March 16, 2010 To release the crown on a maxi marine Text again in case you cant read the green With the crown in the winding position a small lever will be visible here press that while gently pulling the crown. To check you have the right bit open and close the crown from winding pos to hand setting and you will see the lever pop in and out Quote Link to comment Share on other sites More sharing options...
bluemax Posted March 17, 2010 Author Report Share Posted March 17, 2010 An update regarding my original problem with faulty autowind: got it fixed at a local watchmaker, it seems that a couple of parts in autowind section somehow got broken/bent. After replacing them, the watch seems to be working fine. The watchmaker told me that most of the parts from this movement can be exchanged with a certain Seagull one, but did not tell me the exact model.

FxrAndy Posted March 17, 2010 Report Share Posted March 17, 2010 Shame he did not tell you, but nice to know some parts are available, just a shame there is no source for seagull parts Quote Link to comment Share on other sites More sharing options...
nakortheblue Posted March 17, 2010 Report Share Posted March 17, 2010 Thanks for the tip. I've managed to get the stem out. Quote Link to comment Share on other sites More sharing options...
