The Cartier Tank ’Solar Beat’ is my favorite 2021 release, because this is Cartier's first watch that runs on solar. The watch is always ready, as long as you take care of it a little as you do with your mechanical watch. This makes the ‘SolarBeat’ feel much closer to a mechanical Tank watch than a quartz version. If, after months of not being worn, it is taken out of the drawer, after which it turns out that the watch has stopped, then it is enough to put the timepiece in the light so that it can recharge its power supply again. After which you can set the time. It’s my always- ready watch, and it looks as good as the full gold mechanical version."
