The role of energy storage systems in the electrification movement
Tying a home''s energy footprint together with an energy storage system is an excellent step toward electrification that allows the homeowner to realize a number of tangible collateral benefits beyond reducing emissions from fossil fuel-based energy sources. It enables homeowners to manage their energy and take control of its use.
Wow Valjoux 7750
Here''s a nice article with pictures and info about the 7750: The Valjoux 7750 Chronograph - Part 1 - TimeZone A great number of chronos use the ETA 7750 movement these days and I was under the impression that it would be a budget movement that offers acceptable accuracy but nothing to get excited about. Then, after sending it in …
Calibre Combat: ETA/Valjoux Cal. 7750 vs. Cal 7753
The cal 7750 was developed by Valjoux long before this merge-up. As Valjoux is now a part of ETA, what used to be the Valjoux 7750 is now the ETA 7750, with the same specs. Technically, only if it''s a 7750 assembled before this merge up is a true Valjoux 7750. Else, simply call it the ETA/Valjoux caliber 7750. That makes the cal 7753 …

Calibre Combat: ETA/Valjoux Cal. 7750 vs. Cal 7753
The movement was developed by Edmond Capt in 1970, as a fully integrated self-winding mechanism with quick-set day/date based on the Valjoux 7733, a derivative of the Venus 188, a cam-switching chronograph movement design introduced in 1948. The construction involves a main plate (middle), a calendar plate (bottom) and a …
