mog Posted December 9, 2006 Report Share Posted December 9, 2006 I'm still learning so apologies if this is a dumb question or it has been covered elseswhere (i really did use the search facility, honest!). I get the impression that the Asian 21J seems to be a pretty good movement for your money, but how do they fair when used with power reserve? How does the power reserve indicator actually work?

JJFlash Posted December 9, 2006 Report Share Posted December 9, 2006 I have a few Asian power reserve models, VC, Pam, etc. Have all been reliable. As the watch is wound, either by crown or motion, the indicator goes up telling you it has the relative indicated reserve power. Quote Link to comment Share on other sites More sharing options...

As the watch is wound, either by crown or motion, the indicator goes up telling you it has the relative indicated reserve power. Same here. Just, it may happen that the power reserve gauge on the dial does not perfectly fit the actual power reserve of the movement: you may run out of power when the power indicator still points at 10 (or even 15) hours. This is due to the need for a close-with-gen dial, not to a flaw or fault in the 21J PR module. Not a great issue, though: once you are aware of it, you also know how to behave with it.

shultz Posted December 9, 2006 Report Share Posted December 9, 2006 asian power reserve movements are MUCH BETTER than asia 7750 movements @Erdi: Is that for sure? Which asian 7750 do you mean : The old or the new one (28'800) which has been reviewed by The Zigmeister? Quote Link to comment Share on other sites More sharing options...
chrono903 Posted December 9, 2006 Report Share Posted December 9, 2006 This one is accurate and reliable, but i don't know what it is. Thom Quote Link to comment Share on other sites More sharing options...

JWR Posted December 9, 2006 Report Share Posted December 9, 2006 seagull st-25 someone told me it's a very close copy of the 2893 + PR module... Quote Link to comment Share on other sites More sharing options...
2005SUBMARINER Posted December 9, 2006 Report Share Posted December 9, 2006 yes it is .. im very impressed with the acuracey of this movement ! i believe this movement can be made to replace our current eta models in the future Quote Link to comment Share on other sites More sharing options...
Rikske Posted December 9, 2006 Report Share Posted December 9, 2006 After regulation , mine is running now very stable at an average +0.5 sec a day. None of my Eta's 2836 or 2824 can be made so accurate. Quote Link to comment Share on other sites More sharing options...
sssurfer Posted December 9, 2006 Report Share Posted December 9, 2006 I'm afraid we are speaking of different movements. The Asian 21J is actually a copy of the Miyota 8215, not of the ETA 2893. And the ETA 2893 is not a PR movement, but a GMT movement. His PR brother is the 2892-A2. Quote Link to comment Share on other sites More sharing options...

The power reserve function is added to the movement by installing a soprod power reserve module. Quote Link to comment Share on other sites More sharing options...
mog Posted December 9, 2006 Author Report Share Posted December 9, 2006 So what I am hearing is that the an additional power reserve module is added to the movement to give it the PR feature and generally they seem to work fine. I have been looking at the same PAM 090 as you 2005SUB, but I can't really justify the expense of any of the Eta ones. As it is I haven't told the wife yet about the B&R winging its way to me for Christmas! Quote Link to comment Share on other sites More sharing options...

r11co Posted December 10, 2006 Report Share Posted December 10, 2006 The Asian 21J is actually a copy of the Miyota 8215, not of the ETA 2893. And the ETA 2893 is not a PR movement, but a GMT movement. His PR brother is the 2892-A2. A little knowledge, and all that.... The 'Asian 21J' movement in question for power reserve reps IS the Seagull ST-25 which is a modified version of the ST-18 which is a blatant rip-off of the ETA2892 - so blatant that dealers here sell have sold them as 2892s and buyers here happily purchase them. There have been unconfirmed reports that the ST-18 is the result of a (terminated) licence agreement to build ETA parts in China. The ST-18 isn't constructed as well (some rivets used instead of screws), but as Marickville Boy discovered - the parts are almost fully interchangeable. The ST-25 has a slightly different bridge arrangement and the power reserve module, but otherwise it is 'a copy' of the 2892 with Soprod PR. The ETA2892-A2 is just a variant of the 2892 and doesn't have power reserve function as standard. Asian 21J means no more than Swiss 25J (ie. you can't tie that description down to any specific movement). Quote Link to comment Share on other sites More sharing options...
sssurfer Posted December 10, 2006 Report Share Posted December 10, 2006 The 'Asian 21J' movement in question for power reserve reps IS the Seagull ST-25... While the movement posted by 2005submariner is no doubt a Seagull ST-25, mog started this thread asking about the Asian 21J. And the movement usually called 'Asian 21J' IS actually used on power reserve reps, as you can see from these pics of my (TTK's) 027 movement: You are naturally free to call 'Asian 21J' any movement you like, but this won't help in avoiding possible misunderstandings. And in facts, as I already suggested, we were talking about different movements. Quote Link to comment Share on other sites More sharing options...
Watchmeister Posted December 10, 2006 Report Share Posted December 10, 2006 I have to say mine functions beautifully. Replace the case with a non-button case, put on a watchwinder and you have an excellent PAM PR rep. Quote Link to comment Share on other sites More sharing options...

Fair enough, but Mog went on to talk about the PAM 090 rep and my info relates to the specific movement used in that watch. TBH I wasn't aware of the PR movement with the layout you show. A little knowledge and all that..... Quote Link to comment Share on other sites More sharing options...
kidxer Posted January 31, 2007 Report Share Posted January 31, 2007 I have to say mine functions beautifully. Replace the case with a non-button case, put on a watchwinder and you have an excellent PAM PR rep. Where could one get a replacement case without the datechanger in brushed SS (for a PAM222)? thx Quote Link to comment Share on other sites More sharing options...
