are the fenix 6x quickfit straps compatible with fenix 5x series?

Thanks for the response, I saw online they are 26mm but under compatible devices it only listed the 6x devices which is why i questioned it. 

I wonder if the pin may be a different diameter? It seems as though it is a different design, no screw heads on the outside. I hope they don’t use a standard watch pin? Surely not.

The pin on the Marq is quite substantial in diameter and is a spring-pin so I'd guess that's the direction Garmin has taken with the F6. So although it might be classed as a 'standard watch pin' I'd suggest that it might be a bit more robust.

i wonder the same thing? I really like the nylon one. Does anybody know if the nylon bands are more durable than the silicon ones?

Iv'e just tried my 3rd party and original bands from my pervious 5X Pro 26mm and can confirm they all work perfectly on my new 6X Pro Sapphire 

And are they also compatible with the regular 5er models? Really would like the Titanium watch, but the orange strap sucks. 

I am using my Titanium band from my Fenix 5x Plus on my new Fenix 6x Pro Solar and matches perfectly.
