TomTomWatch is a Java application for downloading content from the TomTom GPS watches. I created it because I do not want to use the TomTom cloud for maintaining my tracks.
The software downloads the track files (ttbin files) from the watch. By default the ttbin files are automatically saved in a similar directory structure as TomTom MySports. It is possible to export the tracks to GPX 1.1 format. Since version 0.2 it is possible to upload track planning (routes) from GPX (route must be present as route <rte> or track <trk>). This feature has been greatly enhanced since version 1.5.
I miss the function on the TomTom Watch to log waypoints. A special feature of TomTomWatch is the logging of Waypoints when saving to GPX: when during your workout or trip you pause track logging and resume within 5 seconds (default), the GPX converter treats it as the logging of a Waypoint. If the pause is longer, the GPX converter treats it as the start of a new track segment.
- Unpack the binary zip in a directory of choice. This results in following files (for versin 1.5).
- Modify tomtomwatch.properties, especially define the paths where the application stores the files or looks for files
Alternatively, you can use the makeworkingdirs.bat script to create the working directory that corresponds to the properies file enclosed.
- Start via java -jar TomTomWatch-<version>.jar, where <version> is the version number
- If under Windows the Serial number is shown as ‘Unknown’ (like in the image at the top of this page), use Zadig to replace the HidUsb driver by the WinUSB driver for the device ‘Workout Drive’. This solves the problem.

Refer to the TomTomWatch Design page for the UML design of the application.
Refer to the Reverse Engineering Page for a description of the TomTom Watch interface.
When setting debuggingMenu=true in the tomtomwatch.properties file, an additional menu becomes enabled, allowing to perform file operations. Be warned that you might ruin your watch when using these features.
Height from Google elevation service
Apart from the Adventurer, the watches do not measure elevation. Optionally, the elevation can be requested from the Google Elevation Service. An API key from Google is required.
To enable this feature, set heightService=google and fill in the API key in heightServiceKey in the properties file tomtomwatch.properties. Next graphs show the comparison between the height as measured by the Adventurer and the height data as obtained from the Google Elevation Service. Resolution of the Adventurer is 1 m, clearly visible in the third graph.
Heart rate sensor
The cardio watches contain a heart rate sensor.These sensors measure small differences in blood perfusion in the wrist due to the heart beat. Under some circumstances blood perfusion is too low to measure. These kind of sensors pick up other beats, like pace when cycling or running. Next graph shows the sensor measured heart beat and the heart beat measured by a chest strap during the same run. The latter is far more reliable.
The application is based on the excellent ttwatch application of Ryan Binns.
I provide the software for free, including source code. The software may contain bugs. It might damage your TomTom GPS Watch. I won’t take responsibility for any damage.
