One wrist, two tools. The GT66 keeps a multi-sport watch and a pair of TWS earbuds in the same strap, so training, tracking and calls travel together. Heart rate, sleep, steps and calories show on a round touchscreen.
Two products in one: a multi-sport smart watch with built-in TWS earbuds
- carrying separate earbuds and watch
- tracking health without extra devices
- bulky workout setup
Your workout watch and earbuds, in one strap
Stop juggling a watch, earbuds and a tangle of cables. Track every session and take every call from one device on your wrist.
One strap that carries your earbuds

Earbuds that live in the strap
The TWS earbuds sit in the strap, so the audio gear travels with the watch and nothing gets left behind on the bench. Pull them out for a run, then drop them back when you are done. Pairing is a one-time step, and the Bluetooth indicator on the display confirms the connection.

Track every session
A heart rate sensor sits on the case back, and the round display shows steps, calories and heart rate while you move. Sleep monitoring runs overnight, so you can read the results with your morning coffee. Compared with a basic heart rate fitness tracker, you also get the earbuds.

Metal and silicone, two finishes
A silver metal bezel and crown sit on a black matte case in one colourway, and a silver version pairs a metal bezel with a grey strap. The silicone strap closes with a polished steel buckle, and the layered detailing gives it a firm, finished look.
Detach, pair and go in minutes
- 1Charge the watch and earbuds
Give both a full charge before the first workout so the session is not cut short.
- 2Pair the earbuds to the watch
Lift the earbuds out of the strap and follow the pairing prompt on the display. The Bluetooth indicator confirms the link.
- 3Sync the watch with your phone
Connect the watch to your phone over Bluetooth to check the time, date and step count on the face.
- 4Pick a sport mode and go
Choose a mode on the watch, snug the strap so the heart rate sensor sits flat, and start moving.

One pair, stored in the strap
Less to carry, more to track

The bag that never has everything
Before most sessions, the same scramble starts. A watch that needs charging, earbuds that are nowhere to be found, and a cable that was supposed to be in the side pocket. By the time you start moving, the workout has already lost ten minutes.

One device, not two
The GT66 puts a pair of TWS earbuds inside the strap. The watch tracks the session and the earbuds carry the music and calls, so there is one thing to charge, one thing to pair and nothing to misplace on the way out the door.

Ready for every session
Gym, run or commute, the round display shows time, date, steps, calories and heart rate at a glance. Pick a sport mode, pop the earbuds out, and head into the day with one wrist covered.

Questions and answers
The earbuds sit in a dedicated spot inside the strap, so they travel with the watch instead of loose in a pocket. Seat them firmly when you put them back, and keep the strap snug on your wrist during a run.
The heart rate sensor sits on the case back and reads your pulse through the skin. Readings are steadiest when the strap is snug and the sensor stays flat on your wrist. Look at trends across weeks rather than single numbers, and talk to a doctor about any real health concern.
The watch connects over Bluetooth, and the indicator on the display shows when the link is active. Take calls on the watch and keep the earbuds for music and calls on the move.
The silicone strap is soft against the skin and closes with a metal buckle. Loosen it a notch for everyday wear and tighten it for workouts so the sensor stays in contact.
You get the watch, the strap and one pair of earbuds in one box. That means one device to charge, one to pair and one to carry, instead of buying a tracker and wireless earbuds as two purchases that each need their own charger and case.
