Just received my watch and I can say it looks phenomenal... The cathodes perform well the charging dock is easy to use and the setup is quick. Charge time will be absolutely fast enough for overnight charge.
However. I have received unit 10 and out of the box my second cathode (1) on the 0-9 row is not working and hasnt worked after a full charge either...
I'm aware vaccuum tubes can be fragile but I hope quality control is well executed nonetheless to evade that situation.
Second, Instructions weren't available in the box at the time of writing. You get a qr code to scan which leads to a document folder on google drive that should theoretically house the instructions but the folder is empty...
And third, no tracking during shipping makes the receiving part extremely stressful as you can easily lose the item without being able to retrieve it...

note: I am seemingly unable to change the reading speed for the interface, you are theoretically supposed to be able to change at what speed the readouts flip between hours, minutes and seconds but for some reason I cannot get it to work...
