New battery test, day 600: 2.91 volts. It’s settled: this watch, with its CR2016 coin cell installed in February 2022, will tick its way through a second trip to Pasadena for another visit to Supercon. Haven’t checked in with my buddy Ben, wearing the yellow line watch (with higher consumption due to the hourly beep); he’s abroad through mid November, and I’m wondering if it’ll still be running when he gets back. 🤞🏽
