Time format is used to change between 12 and 24 hours display mode, e.g: 4PM in the afternoon, in 12 hour mode it will show (0 4.) as hours; in 24 hours mode it will show (1 6.) as hours. Select (0 .1.) to enable 12 hours mode, and (0 .0.) for 24 hours mode.

The brightness can be adjusted automatically with the embedded ambient light sensor. The sensor is located between the base of the two nixie tubes. Select (0 .0.) for automatic brightness adjustment; select 1-5 for different level of brightness with 1 being the dimmest, and 5 being the brightest. Changing the brightness settings will have a slight impact on battery life depending on each use case. 

Raise to wake is a function that makes use of the accelerometer inside of the watch to show time everytime you raise your hand. Select (0 .0.) to disable raise to wake function; select (0 .1.) for a less sensitive algorithm and (0 .2.) for a more sensitive algorithm. Noted that a more sensitive algorithm will trigger more unintended activation, and will reduce the battery life.

Automatic battery saving helps improve battery life when the watch battery is below 30%. Automatic battery saving will make adjustment to the following: minimize brightness; turn off raise to wake; turn off animation. Select (0 .0.) to turn off the automatic battery saving, and (0 .1.) to turn it on.

Quick display mode allows the first activation within 10 second to show time at a much faster pace. To turn on this feature, select (0 .1.); otherwise select (0 .0.). When this feature is activated, raise to wake will alway be quick display. Turn on this feature will help improve battery life.

Use the crown to select the number of minutes, then press the button to start the countdown; press and hold to cancel. During the countdown the LED will turn on if the ambient light is bright; it will turn off when the ambient light is dark.

This function is for testing purposes, it records the number that the watch has been turned on. The decimal dots can be read as binary, which should be times 100. E.g: (.1..9) will be decimal value(Binary:1110 = Decimal 14) * 100 + nixie display (19) = 1419 times. You can click to set it back to 0.

there are multiple stages in this mode. Each stage is designed to test a different hardware, press the button to get to the next stage. Each stage is identified with the decimal point at the bottom.

Below are all the stages:

1. intro stage runs all the numbers. It tests the display of the tubes. and you can use the crown to change the brightness.
2. the first stage is designed to test the crown. Every time the crown is rotated, the number should change. Try to rotate both directions, both directions should work (change in the display).
3. the second stage tests the ambient light sensor. It will show 1 if it detects light, 0 if there is not enough lights detected.
4. the third stage tests reading data from the accelerometer. It will show 1 if there is data input, it means the accelerometer is functioning.
5. the fourth stage tests the RTC. It reads the second of the current time. it should run from 00-59.

Factory reset mode or sleep mode puts the watch’s software back to factory settings. It will clear all time data inside the watch then put the watch into sleep mode. During the sleep mode most of the functions will be turned off to minimize battery consumption. This option is very useful when the watch is intended to be stored for a long period of time. To activate sleep mode, set it to 0 .1., then wait for the 10 seconds countdown without pressing anything. If a button is pressed during the countdown, it will go back without going into sleep mode. To turn on the watch again, repeatedly press the button until the watch lights up.
