Review: GTENG T909 FPV Watch – Tiny 2″ LCD Display

Today we are reviewing the GTeng T909 FPV watch with 2″ LCD screen! It’s a really cool gadget with a built-in battery and VRX, providing decent run time and range, all in this tiny package. I have been having fun mounting an FPV watch on my Taranis TX for watching other’s flying and also for testing my FPV setup.

You can get the FPV watch from:

Unboxing the T909

The GTeng T909 FPV watch comes with a USB cable for charging, and a manual. Note that you can only use this cable for charging your watch, normal micro USB cable doesn’t work!

The length of the watch is about 27cm.


On the left there is a USB connector for charging battery, and the foldable antenna.

On the right, there are the power button and channel button.

To switch on/off the GTENG T909 FPV watch, simply hold down the power button for 3 seconds.

Press the channel button to change channels, hold down the channel button for 3 seconds to change frequency bands.


The wrist band is made of some sort of sticky rubber and seems to be attracted to dusts. It probably would feel terrible if you have sweaty wrists.

Impression of the GTeng FPV watch

It’s not a watch!

First of all, you really can’t look at the watch on your wrist while controlling the radio transmitter, not to mention the tiny screen. So to me it makes more sense to use it for watching other’s flying or as a tool to test equipment.

And it’s not really a watch as it doesn’t tell the time. But, you can put a camera/VTX in front of a clock, and set the VTX on Ch7 if you’re desperate :) Just kidding.


FPV Watch Screen Resolution

However the resolution seems to be pretty good, even the little OSD text is readable if you look closer.

There is no noticeable delay comparing to the 7″ monitor I am using. However the LCD screen is not very bright, it can be difficult to see under the sun. Also the viewing angle is narrower than a larger display, at about 45 degrees.


GTeng Watch Signal Range

I tested the range using a FX797 video transmitter on a Tiny whoop micro quad.

From this test, the GTeng FPV Watch has about 90% range as my ImmersionRC Uno V2 VRX with a dipole antenna. It reached about 180m before the video became unflyable, while I got 210m on the Uno video receiver.

Very impressive for something this tiny with a simple antenna hidden inside.

Pros and Cons

I like this FPV watch, it’s an affordable gadget for FPV and simple to use. It has good battery life for the small size, and the reception is also excellent which is more than enough for FPV races.

However the screen is a bit too small as a primary FPV display, though it would be a ton of fun as a spectator monitor.


One major disadvantage is the low brightness. Not to mention that brightness and contrast are not adjustable either. On a sunny day you will have to stand under a shady tree in order to see the screen clearly.

It’s such a good companion with the Tiny Whoop :) Even the colours match nicely.


Modifications and Improvements

The first mod I did to the FPV watch was to remove the wrist bands :) I don’t think I would ever wear it anyway.

In the future I might also change out the battery to some bigger ones. Or maybe remove the internal battery, replace it with a JST connector and drill a hole on the watch so I can plug an external battery in.

Quick note, to access the main PCB and battery bay, you only need to simply lift the screen.

One last thing I noticed was the FPV watch is using a RX5808 video receiver module (which you can get easily in case you want to replace it). That means you can actually take it apart, remove the whip antenna and add a SMA connector to the VRX, so that you can install a higher gain antenna to give you more range :)

Here is the manual for future reference.

Charging your FPV Watch in the Field

The internal battery only lasts about an hour, so it would be helpful to be able to charge it in the field. The easiest solution is to use a LiPo to 5V converter ( Now you can charge your FPV watch with any battery you bring for flying :)

Other Creative Uses

Someone commented on Facebook that he uses this watch as a TV streaming display. He hooks up the AV cable from the TV to a VTX so he can walk around the house with the watch without missing out what’s on the show :)

    Thanks for the great review and all of your help, Oscar! Thanks also for putting up a copy of the manual. So helpful, as I lost mine.

    A chap (shawdreamer) on the Multi forum ( created this which converts the GTeng into a monocule. So in theory you don’t need a spotter as you have 1 eye in direct line of sight of your quad and the other eye is the fpv eye :)
