These are photographs of the actual engineering unit. The finish, the button feel and the strap are not production parts and may change for the production version.
The case, the side buttons, and the strap you wear every day.
That slip road on the way home — the downshift, the throttle, the exit, all of it just right. You would not time a commute, but you still want to know how far it was and how fast on average.
Daily mode starts by itself when you drive off and stops when you park.
Record before and after a tyre change or a damper adjustment and compare how it actually drives.
Commuting, track, off-road and RC all use the same recording format.
STINT rides on your wrist, not on the windscreen,
and there is no power cable to run.
Cross the line and see the delta to your best lap straight away. Back in the pits, open the app for the lap-by-lap detail.
Run acceleration tests only at legal, closed venues suitable for testing. When comparing results, account for differences in tyres, load and conditions.
View pitch and roll readings. Angle values cannot determine whether a vehicle will roll over.
Secure the watch to the vehicle and select VEHICLE mounting mode to display pitch and roll relative to the reference.
Set the reference from the stationary attitude for this session. Valid GPS and enough stationary samples are required. Readings are not absolute slopes relative to level ground.
Set the mounting reference after securing the watch. Set it again whenever you move the mount.
Review climb and roll across the whole route in the app.
Strapped to the chassis it measures climb and roll; held in your hand it measures a rock, a slope or the chassis itself.
Record pitch angles and import them into the app to review changes.
Record changes in roll angle. These values cannot guarantee that a vehicle will not tip over.
No GPS required. Record tilt relative to a reference and sync it to the app. First, follow the on-screen instructions to hold the watch still and zero it.
RC crawlers do not use GPS. They are slow and cover very little ground, so only attitude data is recorded.
Use the built-in GPS day to day. When you need a higher sample rate, pair a RaceBox Mini or a Qstarz — no need to change watches.
All three sources use the same recording format and sync to the app.
Available features depend on the watch firmware and app version you receive.
Video export with data overlays currently supports iPhone. Video export is not yet available on Android.
Updating the watch through a phone is still being tested. For engineering-unit updates, follow the method provided by the team.
Your real-world use, log files, screenshots and notes are what let us confirm problems and plan fixes.
Participants who complete all three test rounds and meet the participation requirements will receive one production unit when production begins. Eligibility is governed by the Test Participation Agreement. If the product does not enter production, this offer does not apply.
Pairing, everyday distance, acceleration runs, automatic lap detection and downloading logs.
Compare the recordings from all three GPS sources, and test the attitude features, video overlay and battery drain.
Sessions over two hours, rain, obstructed sky, time zones and imperial units — plus one scenario of your own choosing.
| Category | Recommended kit | What it tests |
|---|---|---|
| Track / timed sessions | A RaceBox Mini or Qstarz receiver (built-in GPS works if you have neither) | Automatic lap detection, lap-time accuracy, comparison with official timing |
| Daily + 0–100 + mountain roads | An external receiver, RaceBox Mini preferred (built-in GPS works if you have none) | 0–100 splits, distance totals, speed-camera alerts |
| Off-road / trails | A digital inclinometer is recommended | Off-road mode, attitude indicator and mounting calibration (requires attachment to the vehicle and a stationary reference) |
| RC rock crawler | A digital inclinometer or angle gauge | Pitch, roll and FreeTilt handheld measurement |
| Overseas | Not required | Imperial units, GNSS in other regions, time zones |
For the track and acceleration categories, owning a RaceBox Mini or Qstarz counts in your favour, because the testing needs a second source to cross-check against. You can still apply without an external receiver — the watch's built-in GPS (5 Hz) does the job.
