grb 1 Posted May 20, 2011 Looking for some advice please. I have this but it's an asian 21j and its all wrong, chrono doesn't work, but it's got a large second hand running which I suspect shouldn't be, with a very nice sweep. I like it and I'm told it's now out of production. 1.) Is it possible to put in a better movement say 7750 or something to make the chrono work. 2.) And if that's possible does it mean the big second will only be active when the chrono is running. Thanks in anticipation. Share this post Link to post Share on other sites
prestigewatchco 2 Posted May 20, 2011 Not possible G sub dials are wrongly placed. better off selling that and buying the 7750 version if you can find one they are hard to come by at the moment Share this post Link to post Share on other sites
