Admiral by Monjibox, using 4 different sizes tubes: Z5660M made in Germany, IN8-2 made in Russia, ZM1080 made in Great Britain and Z5900M again from Germany. Each group of 2 tubes can be configured to show any of: hour, min, sec, hundredths of a second, day, month, year, day of week in any order. Few predefined templates but also a user fully customizable one.
Hundredths of a second are not 100% accurate due to Nixies activation delay, so you can't use this device as race counter device. Battery backup for timekeeping during power loss. 12 or 24 hour format. Mmddyy or ddmmyy date format.
Automatic DST for US, Europe, Australia or disabled. 4 daily intervals for brightness adjustment (in 10 levels, including off). Customization for special function possible (by our own software developer).
One simple button for all settings (rotate and push).
