that is my fave pic of yours hiro with that yellow material behind it
Just an offtopic, as someone showed a Seiko Solar and I'm feeling too lazy to do a proper search... how does Seiko's Solar watches compare to Ecodrives when it comes to light-spectrum charging, "power reserve" and battery longevity? When I was considering moving to quartz I though about their kinetics but they sounded like a serious PITA. They don't have a lot of solar options, so I'm thinking not quite so refined as Citizen at this point?
I've owned three Seiko solar watches and still have two. I haven't owned them long enough to talk about battery longevity though. They offer a 6-month power reserve like the regular Eco-Drive.
When I received a SSC031 (V175), it wasn't ticking, but after I left it under a full-spectrum LED light for about 15 mins, it started ticking.
Anyway, no problems with mine so far. The V175 is a pretty accurate movement as well.
As for "charging" and "power reserve" I can tell you that the both hold up well. Due to circumstances beyond my control, I had to store my collection of Citizen Eco's and Seiko solar's in the dark for about 5 months. All were still working perfectly when I took them out into day light. I charged them up only because they hadn't seen the sun for so long.
Hope this helps.
I believe that some Citizen battery can be changed. Last I checked the bay it was about $30 for a battery but even if is changed every 10 years or so, that is still great.
A: Time to charge 1 day of power
V157/V158 A (minutes) B (hours) C (hours) General offices/ Fluorescent light (700) 110 25 - 30W20cm/ Fluorescent light (3000) 30 6 120 Cloudy weather/Sunlight (10000) 10 2 35 Fair weather/Sunlight (100000) 2 0.4 9 Expected life per charge from fullcharge to stoppage 10 months Loss/gain (monthly rate) Less than 15 seconds when the watch is worn on your wrist ata normal temperature range (5 oC to 35 oC) Operational temperature range -10 oC to 60 oC
B: Time required for steady operationC: Time required for full charge
The above table provides only a generalguideline.
Update: Couldn't get column headings to align. First column should be A (minutes). Second column should be B (hours). Third column should be C (hours).

...not that I'm planning gtting another one any time soon... but we know that that means until one stumbles upon one that is on sale or on the sales forum or something like that
---EDIT--- Which, btw, just happened after posting this... now, why do I need another solar diver?
