What ETA caliber is c01.211?

The ETA caliber C01.211 is a 15 jewels automatic chronograph movement made by ETA mainly for Tissot, but also Certina. Both brands are part of the Swatch Group conglomerate of Swiss watch companies. Interestingly, Tissot did not apply their own caliber designation to this movement.

How does a c01.211 chronograph work?

The C01.211 movement uses a column wheel to control the start, stop, and reset functions of the chronograph, resulting in accurate and smooth operation. The movement also features a quick-set date function and a frequency of 28,800 vibrations per hour.

How big is a c01.211 watch?

With a diameter of 30mm and a height of 7.9mm, the movement is compatible with watches that have a case size of 41-43mm. The C01.211 movement uses a column wheel to control the start, stop, and reset functions of the chronograph, resulting in accurate and smooth operation.

When was the ETA c01.211 discontinued?

The latter was mostly seen in military- and tool-watches and discontinued in the early 2000's. The new C01.211 is mostly (or only?) found in the lower segment brands of the Swatch Group. Full details and images of the ETA caliber C01.211, including a list of all watches using this movement.

Should energy storage be co-optimized?

Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible. Goals that aim for zero emissions are more complex and expensive than net-zero goals that use negative emissions technologies to achieve a reduction of 100%.

Can long-duration energy storage technologies solve the intermittency problem?

Long-duration energy storage technologies can be a solution to the intermittency problem of wind and solar power but estimating technology costs remains a challenge. New research identifies cost targets for long-duration storage technologies to make them competitive against different firm low-carbon generation technologies.
