The most accurate watches with Eco-Drive are rated within +/-10 seconds per year. The fact that a watch is powered by the Eco-Drive technology has nothing to do with its accuracy. Generally, quartz watches (including most of the Citizen's Eco-Drive models) are accurate within +/-0.5 second per day.Does Citizen give any figures for accuracy on their Eco-Drive watches or does anyone know how they perform please?
Exactly right. Citizen specs their Campanolas to 20 seconds per month. Most of their watches (including eco-drives) are spec'ed to 15 seconds per month. Their high end line (The Exceed line) to 10 seconds per year. The first two are typical for quartz. The last is the kind of performance one gets from modern thermocompensated movements.The fact that a watch is powered by the Eco-Drive technology has nothing to do with its accuracy.
You're welcome! On the SD, there's not a chance it will perform better. It's not thermocompensated. I suspect that the very low current levels created by the SD generator cannot support the extra electronics required.Thanks to both of you.
I saw Bruce Reding's post suggesting that they would do better than the claims and I think you're right....... but will it be better than the GS?
