My Citizen Eco-Drive PC, model BL1184-56L is celebrating its 14th year of uninterrupted service this month. Any others have similar Eco-Drives going as long or longer?
Theoretically, if the battery is not allowed to discharge, it should last forever. This is more the case with the MT920 battery than it is with the CTL920, as the MT can cycle up to 500 times, the CTL only 100. And when Citizen advertises these Eco Drive watches as 'Never needs a battery', they're lying to you. In an oblique fashion perhaps, but lying none the less. Take the 'battery' that an Eco Drive watch never needs, out of the movement, and put it in a dark environment. I've replaced batteries in Calibre 2100 movements many, many times.

I seem to be testing the "theoretically lasts forever" as none of my Eco-Drives have ever discharged completely. Nearest was one that ticked in 2-second intervals until charged more. The E760 movement has power-save modes so is not likely to ever discharge in normal use.
I have a Citizen Titanium Skyhawk C650, and a E812 Perpetual calendar model, both of which are close to 15 years old, and have never let them run down, they're both operating flawlessly. The Calibre 2100, on the other hand, seems to go through CTL920's. That watch has an absolutely stunning dial face, especially when viewed illuminated from an angle. The only way that Citizen could pull this off on an Eco Drive watch is by making the dial face solid. The only light striking the solar panel is though the four sub-dial faces, and that isn't much.
Norm Sir both my Zilla and Ti Zilla Both gave up the Ghost after 11yrs.
Both needing new Capacitors and they were never opened in that time.my Ti Zilla is with Guy as we speak for a service and new Capacitor.
It had also accompanied me on every Freedive competition I ever did.
My Ti Orca is still going strong as are a few other Ecos I have.

Left is a standard one with after market hands in bezel insert.
Middile is modded with 6105 dial, hands and rotating bezel
Right is with an AM scubapro dial and hands, although I think they're a bit too white.
Well I am sure this has been seen already.
Fake Seiko 6309-7049 case kit on our favorite site. Might be good for a beater project. Love the engraving inside the case back.

Not sure about any of the Seiko Boutiques except for sure the flagship Boutique in New York City. In the past besides being a Grand Seiko Boutique they also carried the best (and most expensive) of the Prospex and Presage upscale 'non-GS' models. It adds so much to the experience to see the...
