![]() No real technical information is found in the manual under “Specifications” (at least that I could find), including the quartz oscillator frequency. Interestingly, the manual states: “To maintain this timekeeping accuracy, you must use the watch at ambient temperature (between +5 ☌ and +40 ☌) and carry it with you approximately 12 hours a day.” (Boldface mine.) I suppose we might assume that Citizen means to wear the watch approximately 12 hours a day. The specified accuracy is the same as that of the Chronomaster, within ± 5 seconds per year. In addition (also in line, I think, with the Chronomasters), Citizen offers two inspections and timing adjustments, free of charge, during the first 10 years of ownership, the first in the second year of use, the last in the eighth. These latter Seikos (at exactly the same MSRP as the new The Citizens) represent lesser quality than those GS quartz models of the past, with the differences being largely aesthetic.įirst, Citizen appears to have carried on the truly-excellent 10-year warranty with these new models. As an aside, Citizen appears to have followed Seiko with the latter’s introduction a couple of years ago now of their less-expensive Grand Seiko quartz models, designed for the international market-SBGX059, 061, 063 and 065. This all suggests some cost-cutting steps in the materials and manufacture of AQ1000-58-series models (appearing in aesthetic differences), and these will be identified later in this review. Like AQ1000-58E, this Chronomaster has a stainless steel (SS) case and is thus is less expensive than the titanium Chronomaster models. For example, the closest Chronomaster, CTQ57-1202 has a MSRP of 262,500 JPY. These prices are significantly lower than those of the Chronomaster series. Bargains are available, with 160,000 JPY being offered by some suppliers. As an additional resource, the manual for this new watch can be found at:Īt this point, there are two other models using this new A010 movement, AQ1000-58A (champagne dial) and AQ1000-58B (silver dial). In each picture, the AQ1000-58E is on the left and the older Chronomaster CTQ57-0955 on the right. I had a friend take them with my help, but neither of us is exactly photography-savvy. I’ll start the review with some pictures, for the quality of which I must apologize. I guess until that is done, we won’t know whether the newer Citizen A010 movement is little more than an A660 adapted for a light-replenished battery or something completely different. This review will be pretty superficial since I lack the intestinal fortitude to unscrew the back and look at the movement. A few weeks ago, I received The Citizen, Model AQ1000-58E, the new “eco-drive” (light-cell replenished battery) version of the quartz The Citizen (lord, that’s an awkward locution, but that’s the model’s name!) Since many HEQ forumers are already familiar with its predecessor, the Citizen Chronomaster (and since I have one, CTQ57-0955), it seemed like a good idea to review the newer model beside the older one.
