fightfear 0 Posted October 17, 2011 What is the difference between 21j Autoamtic and Japan OS? Sorry if this has been asked here before but I can't search for anything right now - my laptop is damaged and I can barely get it to view and post I'm debating whether to go for this one http://www.timeshops.net/9933-ca5240-carti...hronograph.html or that one http://www.timeshops.net/9964-ca7090-carti...-automatic.html Hence my question Share this post Link to post Share on other sites
amuthon 0 Posted October 17, 2011 First one has a quartz movement, reliable and accurat in timekeeping, but no sweeping second hand. Second has a cheap automatic/mechanical movement with sweeping second hand. Share this post Link to post Share on other sites
robznet 0 Posted October 17, 2011 First one will be quartz - ie battery movement, second is mechanical. Chrono will work as per gen on the first. It will not work on the second! Share this post Link to post Share on other sites

fightfear 0 Posted October 18, 2011 (edited) Thanks Which of the two is considered superior on here? (taking into account that the second one has a feature that doesn't work) Edited October 18, 2011 by fightfear Share this post Link to post Share on other sites
seclark007 11 Posted October 18, 2011 It depends on what you are looking for. If you want a mechanical watch that doesn't rely on a battery and may or may not require professional adjustment, then get the 21j or better mechanical watch. This watch will also look closer to genuine based on the movement of the second hand - or it's sweep. If you want something that all the bells and whistles work; requires little to no maintenance; but has the trade off of the "telltale ticking second hand" that gives your watch away as a rep, then go with the quartz. So what?! If you just like the looks, go for the quartz. If you want the looks, and you want it to function like the gen, then go for the mechanical movement.
