Free trial for 24 hours after install. After that everything is available with a one-time purchase $1 (+VAT) (see TRY IT FREE). Vacuum Tubes Retro Watch: the time glows in four big cold-cathode tubes, and a split-flap departures board shows the date and your stats. TUBES - Four large nixie tubes show the hours and minutes, with the bent-wire cathodes and glass visible. - Every digit glows equally bright. - In 12-hour mode the hour keeps its leading zero, so all four tubes are always lit. DEPARTURES BOARD - The date, e.g. WED 01 OCT, in your watch's language (AM/PM in 12-hour mode). - Three data fields of your choice, on flaps with labels. - When you raise your wrist, the flaps that changed flip over. You can turn this off. - On MIP watches the board drops the flaps for plain, larger text that's easier to read. LAMP - A fourth data field in a glowing window above the tubes. DATA FIELDS Heart rate, steps, watch battery, Body Battery, stress, calories, floors climbed, intensity minutes, distance today, next sunrise/sunset, temperature, altitude and notifications. TWO CABINETS - Brass Glow: black bakelite, aged brass and orange tubes. - Ruby Valve: oxblood enamel, ivory and nickel with red-orange tubes. ALWAYS-ON On AMOLED watches, the always-on screen shows only the dimmed glow of the digits and the date. It moves slightly every minute to protect the screen. MIP watches get their own crisp 64-colour version. TRY IT FREE All features are free for 24 hours. To keep the data board afterwards, unlock the full version through KiezelPay: the watch face shows your purchase code; enter it at kzl.io/code. Without unlocking, the tubes keep showing the time. SETTINGS Garmin Connect app → Connect IQ → My Watch Faces → Vacuum Tubes Retro Watch → Settings. The cabinet can also be changed on the watch.

First release: four nixie tubes, a split-flap departures board with the date and 3 fields, a lamp field, and Brass Glow and Ruby Valve cabinets.
