Which one fits you

On wrists narrower than about 54mm, the Samsung Galaxy Watch8 LTE Classic is the safer pick — it stays proportionate down to roughly 49mm, where the Garmin Epix Pro Gen 2 51mm starts to hang over the edge. Above 54mm both sit cleanly, and the Garmin Epix Pro Gen 2 51mm gives you more presence.

The Garmin Epix Pro Gen 2 51mm wears larger than the Samsung Galaxy Watch8 LTE Classic (51mm vs 46.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Samsung Galaxy Watch8 LTE Classic is the slimmer of the two (10.6mm vs 14.9mm), so it slides under a cuff more easily.

On the wrist the Samsung Galaxy Watch8 LTE Classic feels lighter (63.5g vs 98g, case only).

Among the 48 51mm watches we hold thickness for, the Garmin Epix Pro Gen 2 51mm is thinner than 90%, so it wears flatter than its width suggests.

Among the 158 46mm watches we hold thickness for, the Samsung Galaxy Watch8 LTE Classic is thinner than 97%, so it wears flatter than its width suggests.

Garmin Epix Pro Gen 2 51mm vs Samsung Galaxy Watch8 LTE Classic on a wrist

  • Garmin Epix Pro Gen 2 51mm 51mm case, standing 14.9mm off the wrist.
  • Samsung Galaxy Watch8 LTE Classic 46.4mm case, standing 10.6mm off the wrist.

Whether that clears your wrist edges is the question worth answering, and it depends on your wrist rather than on the case diameter.
