No emulator for gear fit 2 till now actually ... But you can make almost environment by doing some modification .... See this post https://stackoverflow.com/questions/47883225/emulator-for-samsung-gear-fit-2-tizen

I am putting the contents of that post here ... 

Till now there is no Emulator on Tizen Studio for Gear Fit series. But you may run your projects on Square Emulator in order to test Fit series projects. You can fix the resolution of your project from config.xml.

As the resolution of Gear Fit 2 is 216 x 432, i am setting height and width accordingly.

<?xml version="1.0" encoding="UTF-8"?>
<widget xmlns:tizen="http://tizen.org/ns/widgets" height="432" width="216" xmlns="http://www.w3.org/ns/widgets" id="http://yourdomain/XXXX" version="1.0.0"  viewmodes="maximized">
   ........
    <tizen:setting screen-orientation="portrait" context-menu="disable" background-support="disable" encryption="disable" install-location="auto" hwkey-event="enable"/>
</widget>

And taking the emulator having resolution 320 x 320 as there are no other square emulator option on the Tizen Studio. Hopefully this technique will solve your problem.

Thanks André Reus,

But I have found those erros:

config.xml

<?xml version="1.0" encoding="UTF-8"?>
<widget xmlns="http://www.w3.org/ns/widgets" height="432" width="216" xmlns:tizen="http://tizen.org/ns/widgets" id="http://yourdomain/SettingsUI" version="1.0.0" viewmodes="maximized">

    <tizen:profile name="wearable"/>
    <tizen:setting screen-orientation="portrait" context-menu="disable" background-support="disable" encryption="disable" install-location="auto" hwkey-event="enable"/>
</widget>

Errors:

I'm running the application over wearable-2.3.1 plataform (emulator)  with the following main parameters:

• Device: 320x320 Wearable
• Resolution: 320x320

What am I doing wrong?
