What size band does the Fenix 6X Pro Solar Edition take?

Lug width

26mm

Garmin QuickFit: the strap latches over a fixed bar, so a replacement has to be a 26mm QuickFit strap (Garmin's or a third-party QuickFit one), not an ordinary pin strap.

Fenix 6X Pro Solar Edition — Frequently Asked Questions

Is the Garmin Fenix 6X Pro Solar Edition thick for a 51mm watch?

At 14.9mm, thinner than 87% of the 52 smartwatches 51mm across that we track, so it slides under a cuff more easily than most of its size.
