What I really want to talk about is why high accuracy quartz movements are important. Some people suggest their relevance is limited given the availability of radio controlled watch movements that receive local atomic clock radio signals. While radio controlled watches are very cool, they lack at least two important traits. First radio controlled watches are not fully independent. They require being in the vicinity of the atomic clock radio towers (of which there are six in the world currently). If you are not within range, they are just ordinary quartz watches. A thermoline quartz movement is fully independent. Second, radio controlled watches take a lot of battery power. For that reason they aren't in receive mode all the time. Only occasionally do the receive the radio signals so that they can update themselves. Thus, you'll find that most radio controlled watches are either solar powered, or need to have their batteries changed more often. The Citizen A660 thermoline quartz movement does not have a high energy draw, and is better suited to longevity that radio controlled watches. These are pretty compelling reasons in my opinion to consider thermoline quartz movements special. The Citizen Chronomaster watch collection starts at about $1,900, and this one is likely under $1000 (there is a reserve on the auction, but I promise it is likely less than $1000. Further, these watches are very hard to find in the US. I would certainly consider them great for everyday wear or as a collector's item.
