GMT 4 Settings

GMT4 is the most flexible watch face available. With up to 4 different time zones and over 40 user settings GMT4 is hundreds of watches in one. Build your own customised unique watch face as you control the style, colours, layout and much more.

Time zones can be shown in 12 or 24 hour formats or a 'second' hour hand can be displayed. This feature can also be enabled to be displayed only when outside your 'home' time zone, a great feature for frequent travellers

The alternative time zones can also have Daylight Savings Rules applied depending on which country and city you might using.

User Settings

Show Time as 24 hour Clock – Show the clock in ‘military’ style where there are 24 hours on the watch face rather than usual 12.

As at 31st May 2018 this feature has been removed from GMT 4 Master to reduce memory usage and support internet connectivity features.


Time shown on 12 hour face

Time shown using 24 hour face

Show Watch Logo - Controls which of the 5 available logo's to display on the watch face.

Show Alarm Icon - When selected a small g icon will show if active Alarms are currently set.

Show Battery Icon - When selected an icon a b c d e will appear to show battery status. When battery drops below 10% the icon will change colour to red e and display regardless of this setting.

Note: If you are using GMT 4 Master with the 'always on' second hand you are restricted to a colour palette of 4 colours. In this case the icon will display in the same colour as the Numbers when battery drops below 10%.

Show Phone Connected Icon – When selected an j icon will appear to show the watch is connected to the phone.

Show Notification Icon – When selected an t or u icon will appear to show that unread notifications exist.

Show Second Hand – Display the second hand when in full power mode. Due to processing time on some devices this can skip seconds at times. If this bothers you turn if off!

Most Garmin devices drop to low power mode after a few seconds and at this stage the second hand will disappear. On these devices it is not possible to always display a second hand as updates are only received once a minute in low power mode.

Garmin have a new feature to support an 'always on' second hand available on Fenix 5, Forerunner 935, Vivoactive 3 and Descent Mk1 devices. For these devices if you want to have an 'always on' second hand you will need to install the go to Garmin App store...GMT4 Master version of the watch face. When Show Seconds is turned on for these devices the second hand will appear all the time.

When running GMT 4 Master and the 'always on' second hand there is a limitation of a maximum of four colours in your colour scheme.

The basic watch face is saved as a image on the device and then the second hand drawn over this in its new position each second. Whilst GMT 4 Master can support 16 different colours the memory taken to store the image is currently so large it fails to load on most devices. To work around this you can still select from the 16 different colours however you can only have a maximum of 4 different colours defined for your watch face, including the 'home hand' even if not shown!.

If you exceed the four colour limit the watch face will still display however the colours you selected will not! The colours will default back to grey or other colour in your selected palette rather than the colour defined in your settings. From release 2.3.10 of GMT4 Master if more than 4 colours are used the second hand will no longer display until the colour palette has been reduced to 4 colours.

Home Time Zone

Allows user to set a home time zone that will be displayed when outside that time zone. The colour for the extra hand can also be set. This allows the time at home to be displayed with a ‘second’ hour hand when travelling. The additional hand can also be shown as a ‘24’ hand for those devices that have a 24 hour bezel on the outside of the watch.


Home Time Zone set to 'None'

Home Time Zone to show GMT+7

When the Home Time Zone is set an additional hour hand will appear to show the time in that zone. This additional 'home hand' will only be displayed when you are not in that zone. This is for the frequent traveller who wants to see what time it is at 'home'

The 'Home Time Zone' can be set to any other time zone in order to display the time in that zone if you wish. In that case it would be hidden if you ever travelled to that zone.

Minor Dial Spacing – Control how the dials are located on the watch face there are 3 alternative positions for grouping the dials:

  1. At 10, 2 and 6 o'clock positions.
  2. At 9, 3 and 6 o'clock positions.
  3. At 9, 12 and 6 o'clock positions.

Position minor dials at 10, 2 and 6 o'clock

Position minor dials at 9, 12 and 6 o'clock

Dial Size – 2 dial sizes are supported. On larger watch faces such as Fenix 3 HR, Fenix Chronos, etc the user selected dials can be larger. Using the smaller dials does allow more space on the watch face for some of the bigger number fonts. Selecting larger dials on smaller watch faces or semi-round devices may overlap with other features or get trimmed at the bottom of the display. They are still available for use as it is up to you to define the look of your watch.


Dial size small (9 o'clock) and large can be mixed.

Using large dial and 'digital' dial on semi-round device

Dial 1 to 3 - set the information to be show on the dial. This can be:

  1. None – turns off dial in that position.
  2. Alternate time zone 1 in 12 hour format – shows time zone 1 using a 12 hour dial.

  14. Activity (with Battery) – k Shows battery level percentage as a number in the middle of the dial and the percentage goal activity performed for the day as a progress indicator on the outer edge of the dial.
  15. Activity (with Temperature) – x Shows latest temperature (Celsius or Fahrenheit) from history file as a number in the middle of the dial and the percentage of goal activity performed for the day as a progress indicator on the outer edge of the dial.
  16. Activity (with Pressure) – Shows latest atmospheric pressure (kPa or inHg) from history file as a number in the middle of the dial and the percentage of goal activity performed for the day as a progress indicator on the outer edge of the dial.

    Whilst some devices have the ability to set the display units for pressure this setting is not available for use via the Garmin SDK so the setting for Distance Units is used to control display in metric (kPa)

  17. Day and Date – Shows the current date along with an indicator to show the Day of the week in the outer dial. The day of the week can be shown as short day string or a number.
  18. Sunrise/ Sunset – q Shows the hours of daylight on a 24 hour dial as a progress bar on the out edge of the dial. Note: This calculation is based on current location. If you do not have GPS signal watch will default to last known location or show 0:00 time.
  19. Sunrise/ Sunset (as Text) – q Shows sunrise and sunset as text in 24 hour time.

If you are more than 100 m/ ft above sea level a label will appear on the dial to indicate the base number for dial. The accuracy of the altitude is based on your device. My experience is that they are very good at calculating Latitude and Longitude but less so for altitude!

    Whilst some devices have the ability to set the display units for pressure this setting is not available for use via the Garmin SDK so the setting for Distance Units is used to control display in metric (kPa)

  27. Alternate time zone 1 Digital format – shows time zone 1 using a 24 hour digital format with the time zone label.
  28. Alternate time zone 2 Digital format – shows time zone 1 using a 24 hour digital format with the time zone label.
  29. Note: for battery performance reasons Heart Rate is taken from most recent entry in history file. This is close to current but may vary slightly.

    Note: Not all dials are supported on all devices. Content will vary depending on Garmin support for various features and versions of software development kit. See Support page for details.

Note: For GMT 4 Master, due to the restriction of having only 4 colours in the colour palette, if the 'always on' second hand is in use the day indicator on the Day and Date Dial used the same colour as the Minor Dial Hand (see Example 1 below). If the Minor Dial Colour and the Minor Dial Hand colour are the same then the indicator will be red (see Example 2 below). If your second hand is turned on and their are more than 4 colours in your palette then the device will default to an approximate colour it can support (see Example 3 below).


Example 1

Example 2

Example 3

Show Activity Progress with a Marker – show the activity progress on the watch face between 7 o’clock (0%) and 11 o’clock (100%) positions.

Show Sunrise/ Sunset on Main Face – a small 'triangle' indicator appears on the main face during the sunrise or sunset hour at the corresponding minute position. The indicator only appears during that hour. For example if sunrise is at 6:20am then from 6:00am until 6:59am a small marker will appear at the 23 minute position.

Show Day and Date Box – A day date window can be displayed at 3 alternative positions. This window can be the day and date or just the date. Positions for the window are:

The colours for the Day and Date box are the same colour settings as used on the minor dials. See examples below.


Example 1

Example 2

Example 3

Use Large Pivot for Hands - When set the pivot at the centre of the watch will be slightly larger than the width of the hands. When disabled the pivot will be smaller, giving the view that hands are pinned to the face.

Extended Hands - When set the hands will extend past the centre of the watch face. Gives a more balance look to some styles of hands.

Hand Style - Select style to be used for hands on the watch face


Select Hand style from 7 available styles

Hand Width - set width for hands from Extra Narrow, Narrow, Normal or Wide.


Width of Hands can be 4 different sizes.

Style for Number Style - set if numbers should be displayed on watch face or if a single, double or triangle shape indicator should be used.


No Numbers, single indicator

No Numbers, double indicator

No Numbers, triangle indicator

Show 12 o'clock only

Show major numbers at 12, 3, 6, and 9 o'clock

Show even numbers only

Note: On devices that are not round (eg. Forerunner 230/ 235) some of these styles may cause an overlap on the display with the alarm indicator if this is enabled as there is not enough space on screen to show these. On smaller screens selecting the no numbers or major numbers only option looks the best.

Number Font - select the font to be used for numbers.


Select from 8 different font styles available for numbers

License Activation Key - Enter the Activation Key you purchased to activate additional features.

All features for GMT 4 Master are supported in the free version except for the ability to apply different profiles according to user defined schedule. This allows you to define which watch profile to apply at different times of the day during the week. This feature requires internet server infrastructure to support it and as such is a 'user pays' basis. You can purchase a key by going to the GMT 4 Master Configuration page and following the instructions to sign in and purchase a key.

Once you have activated your key the watch will check that it is using the correct profile every 5 minutes. If your watch is not connected to your phone or your mobile device does not have internet access the update will fail and the watch will continue to use the current profile. The watch will continue to check every 5 minutes.

If your watch supports the 'Do Not Disturb' feature and it is enabled then GMT 4 Master will automatically go into 'Power Saving' mode during this period and the 1 second refresh of the second hand will be turned off. The internet check every 5 minutes will also be turned off.
