How to Measure
1

Lay arm flat, palm up.

2

Measure the flat width across top of wrist.

Garmin epix™ (010-01247-00)
Case: 50.8mmL2L: 53.3mmThick: 17.8mm
BoldOnly 0.85mm clearance. Maximum presence, borderline overhang. For confident wearers.
Garmin fēnix® 8 – 51 mm, AMOLED (010-02905-10)
Case: 51mmL2L: 51mmThick: 14.7mm
Sweet Spot2mm clearance. Perfect for sports watches - bold presence, no overhang.

The Garmin epix™ and Garmin fēnix® 8 – 51 mm, AMOLED share a near-identical 50.8mm case, so wrist presence comes down to thickness, lug-to-lug and weight.

The Garmin fēnix® 8 – 51 mm, AMOLED is the slimmer of the two (14.7mm vs 17.8mm), so it slides under a cuff more easily.

On the wrist the Garmin epix™ feels lighter (85g vs 102g, case only).
