Fénix 6 case material

Hello,

I was under the impression that all the fénix 6 models have fiber-reinforced polymer cases, but as mentioned on Facebook, the Garmin site states that e.g. the

fēnix® 6 - Pro and Sapphire Editions

Sapphire - Titanium with Ember Orange Band

PART NUMBER 010-02158-13

has case material:

"stainless steel, titanium or Diamond-like Carbon (DLC) coated steel"

(still it looks like plastic in the picture...)

Does anyone know for a fact what is true ?
