Night & Day user manual



A watch face with customizable night and day themes and options to display many different kinds of information on two screens.


Custom Settings

To change the settings, follow these instructions: Changing Garmin Connect IQ app settings



The day/night theme changes automatically on sunrise/sunset. The calculation of the approximate sunrise/sunset times relies on the GPS location from your last activity, so if you get wrong sunrise/sunset times, please try to open an activity that uses GPS and get it to lock. The themes can be customized by choosing the colors for background, foreground, time and ‘arc’ (which means the analog seconds on the first screen and the digital time box on the second screen) , and optional animated sky wallpaper.

Default night theme


Default day theme



Theme customization

The theme colors can be modified for day and night time separately, and the sky wallpaper can be set to:

  • off (disabled)
  • night (always moon and stars + cloud)
  • day (always sun)
  • on (moon and stars at night, sun at daytime + cloud)


The colors are coded by numbers:64-color-legend

Please note that this is only a rough guide and the actual colors might look different on your watch. In particular, the older watch models support only 16 colors, so your choice of color from the above palette will be mapped to the nearest color supported by the watch.

For example, if you change the default day theme by changing the ‘Day Fg’ to 1 and ‘Day Arc’ to 33, you will get something like this:




Sunrise and sunset marks

The approximate sunrise and sunset times are marked at a position on the face perimeter corresponding to the analog time of the event. The sunrise mark is a little chevron pointing up and the sunset mark is a little chevron pointing down. After a new installation of this watch face, the sunrise will be at 00:00 (12am) and the sunset at 23:59 (11:59pm). To position the marks correctly, you need to switch to an activity such as running or cycling and lock the GPS signal. Please note that if you change your location, the watch face is not able to detect it automatically. You will need to lock the GPS again to update it for the correct sun times calculation.


Sky objects

These include the Sun and a cloud at daytime, the Moon, stars and a cloud at night. The position of the Sun or the Moon corresponds to the analog hour, and the position of the cloud corresponds to the analog minute. The stars shift randomly every minute.

If you observe your watch during sunrise or sunset, you can enjoy a simple animation of the Sun moving across the horizon.



There are 4 different options for the time font on both screens.


Analog seconds

On the newer watch models, beginning with fenix 5, the first screen can display an analog seconds indicator around the face perimeter. It can be configured either as an arc:


or dots:



The width of the arc or the diameter of the dots is adjustable with the ‘Seconds size’ setting, with 5 size options from XS to XL.

The analog seconds require the watch to wake up to redraw part of its screen every second, so obviously this will increase the battery drain in everyday use. For improving the battery endurance, there is an option to switch the analog seconds off, or to have them enabled only during daytime (from your wake time to bed time declared in Garmin’s user profile).


Real Time HR

This is only available on the newer watch models with a wrist HR sensor, from fenix 5 on. To activate it, you need to do two things: 1) make sure the ‘Real-time HR’ tick box is checked, 2) choose ‘Heart Rate stats’ for Screen1: Opt2. Please note that this feature is tied to the active status of the ‘always on’ seconds. So if you set the seconds to ‘Off’, or at night time when the seconds are set to ‘Daytime’, the HR will not be updated ‘real time’. Also please be aware that updating the HR every second will increase the battery drain.



For extra display space, an optional second screen can be activated for about 10 seconds by raising the wrist. It may take some practice to control the switching between the two screens – generally if you want to look at the first screen, raise your wrist gently, otherwise be more vigorous. It is also worth noting that you don’t need to wait 10 seconds to return to the first screen – moving your wrist in the opposite direction will switch it back immediately. To see how it works, you can experiment by repeatedly turning your watch face up and face down and then altering the pattern, trying different angles.


Base screen

The base screen always shows time, status icons, approximate sunrise/sunset times and the moon phase at night. It can also display an optional steps goal progress icon and three configurable data fields.


Second screen

The second screen shows time with seconds and four configurable data fields.


Data fields

The configurable data fields can be set to display any of:

  • Distance and Calories
  • Calories and Active Calories **
  • Alternate time 1 or 2
  • Steps counter vs. Steps goal
  • Move alert level 1 to 5, like in the move bar but adding an inactivity timer ***
  • Heart Rate stats with an option to update the HR every second *
  • Intensity Minutes *
  • Floors or Climb info *
  • Past 7 days history of steps, floors *, goal completion *, distance, calories or intensity minutes *
  • 4 hours graph of ambient temperature, atmospheric pressure, HR or elevation *
  • GPS latitude, longitude
  • Altitude
  • Sunrise, sunset, moon age
  • Temperature and Atmospheric Pressure *
  • Battery info (level, hours since charged: remaining hours estimation)


The date format is very flexible. It may require some effort to understand how it works, but it allows you to make it almost any way you like.

To customize the date, enter a string of characters up to 12 in length, with this coding:

D = day number with leading zero

d = day number without leading zero

M = month number with leading zero

m = month number without leading zero

Y = 4-digit year

y = 2-digit year

N = month name

n = day name

W = ISO week number with ‘w’ in front

w = ISO week number without ‘w’

Any other character (e.g. – / : . ) will be displayed if it is available in the current character set.


Steps/Move status

Moving icon

This optional icon tracks the user’s activity measured in steps. It combines the functionality of the ‘steps bar’ and ‘move bar’ seen in various other watch faces, including the Garmin’s built-in ones. Its starting point is the sunrise mark, and it moves towards the sunset mark around the face perimeter as you proceed towards your daily steps goal. When the goal is reached, the icon disappears, you’re done!

But if you stay still for an hour or longer, the icon will change colors every 15 minutes, from black to dark blue, purple, orange and finally red. After another hour of inactivity, the icon will change to a little STOP sign.

To clear it back to its normal state, you need to walk for a while. It seems that the longer you stay inactive, the longer it takes to clear the inactive status. Please note that the sensing of the user movements is handled by the watch internally, and the watch face only relies on the status reported by the watch.

Move alert optional field

As an alternative or a complement to the icon, this field shows the numeric inactivity level:

1 = 1 hour of inactivity (blue icon)

2 = 1 hour 15 minutes of inactivity (purple icon)

3 = 1 hour 30 minutes of inactivity (orange icon)

4 = 1 hour 45 minutes of inactivity (red icon)

5 = 2 hours of inactivity (STOP icon)

Besides that, the field also shows inactivity timer that starts counting after 1 hour and clears when the inactivity level goes back to zero (which corresponds to the “Move bar cleared” alert shown by the watch).


Battery Statistics

This field combines three pieces of information:

  • current battery level
  • time since last charge

In this case, ‘last charge’ means the last time a level increment of 1% or more was detected. So even after a short charge, the time counter will get reset to zero.

  • estimated remaining time

Please note that this is just an estimation and it can’t be accurate in all cases, as the battery life depends on varying usage patterns. The estimation is based squarely on the recorded discharge rate (i.e. how many % of the battery has been used vs. the time it took) and an assumption that the discharge rate is roughly linear (which means that for example discharging from 90% to 80% will take about the same amount of time as discharging from 20% to 10%)

In my tests I found that the estimation was reasonably accurate in most cases. A notable exception is the short period after a fresh charge following a new installation, or after Night & Day has not been the active face for a while – in these situations the estimated time may be too optimistic. The accuracy of the estimation tends to improve over time.


Battery Drain

This watch face was optimized to reduce the battery drain, but you need to be aware that your choice of configuration options will have impact on the watch endurance between charges. In general it is expected that activating the second screen, 1Hz seconds, ‘Real Time HR’ and complex data fields (history/graphs) will drain the battery faster. Please note that an option is provided to enable 1Hz seconds (and HR) during daytime only, so that the battery drain at night is reduced – hopefully you don’t need them when you are supposed to be sleeping. ‘Day’/’Night’ is determined from the user settings (bed time / wake time).

The ‘Battery Stats’ data option can help you figure out how different configurations affect your battery life. This field tells how long it has been since the last charge and how many % of the battery was drained, and tries to predict how long your watch will last if you continue to use it as you did since the last charge.



* Some features are only available on certain watch models:

  • HR features: watches with a wrist HR sensor
  • 4hr graphs: CIQ 2.x watches with relevant sensors
  • Intensity Minutes, ‘Do not disturb’ icon: CIQ 2.x watches
  • Temperature, Pressure, Floors: Watches running CIQ 2.x with temperature and barometric pressure sensors

* This watch face was designed with flexibility in mind, but the downside is that in some cases long data may be clipped at the edges on round watches. If this happens, on round watches you may try to configure the display in such a way that the longer fields are closer to the middle of the screen.

* The weekly total in the Intensity Minutes field will be different from the total in the history field because it takes into account today + previous 6 days and the history covers the past 7 days, not including today.

* For ‘Real Time’ HR that is updated every second, please choose ‘Heart Rate stats’ for Screen1: Opt2.

** Active Calories are calculated based on the total calories info retrieved from the watch and the Mifflin St Jeor formula for Basal Metabolic Rate.

*** The move alert with inactivity timer only shows if your status is inactive, when you are active it is hidden.
