Although this is not an Eco-Drive watch, there are light-powered versions of The Citizen as well.

The dial is especially commendable – this model has a very deep, blue-black dial, with a lustrous, almost gem-like finish. The obvious point of comparison is Grand Seiko, and while I feel that they still has an edge over The Citizen in terms of overall fit and finish, The Citizen still very much gives a definite and very positive impression of refinement and quality. The externals of The Citizen are pretty much what you would expect from a flagship, high-accuracy quartz wristwatch from Japan. There's a tendency among mechanical watch enthusiasts to regard quartz watches as essentially all the same (and fundamentally unworthy of serious consideration) but this view, while it may be understandable, ignores the fact that there are, both functionally and aesthetically, sometimes very marked differences between the movement in a thirty or forty dollar entry level quartz watch, and one found in higher end offerings from brands as diverse as Breitling, Bulova, and Seiko, all of whom have in their current lineups, quartz watches that represent extremely dramatic improvements in quality and accuracy over more conventional offerings.

The world of 'High Accuracy Quartz' watches (as they've been dubbed by the online watch community, where 'HAQ' is a recognized acronym) is a highly specialized one, but within that world, there are a number of technically intriguing timepieces, including such forgotten exotica as the Pulsar PSR-10 and PSR-20, which were accurate to, respectively, 10 and 20 seconds ± per year.
