Watch Fit Tool

For sports watches, Lug-to-Lug (L2L) is what matters most. Bulky is fine — overhang is not.

Which one fits you

Both need much the same wrist — roughly 48–66mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.

The Garmin Descent™ G1 Solar wears larger than the Samsung Galaxy Watch8 - LTE · 44mm (45.5mm vs 43.7mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Samsung Galaxy Watch8 - LTE · 44mm is the slimmer of the two (8.6mm vs 15.2mm), so it slides under a cuff more easily.

On the wrist the Samsung Galaxy Watch8 - LTE · 44mm feels lighter (34g vs 66g, case only).

Among the 461 46mm watches we hold thickness for, the Garmin Descent™ G1 Solar is thicker than 82% — it will sit high even though the case width reads modest.

Among the 303 44mm watches we hold thickness for, the Samsung Galaxy Watch8 - LTE · 44mm is thinner than 99%, so it wears flatter than its width suggests.

Every case drawn to scale on a shared centre — from above, and in profile against the wrist. Built from the measurements, so it works for every watch whether or not it has a photo.

Garmin Descent™ G1 Solar vs Samsung Galaxy Watch8 - LTE · 44mm on a wrist

Put Garmin Descent™ G1 Solar and Samsung Galaxy Watch8 - LTE · 44mm on the same arm, sized to your own wrist, and turn it. Side by side or stacked on one spot, whichever answers the question faster.

  • Garmin Descent™ G1 Solar 45.5mm case, standing 15.2mm off the wrist.
  • Samsung Galaxy Watch8 - LTE · 44mm 43.7mm case, 46mm lug-to-lug, standing 8.6mm 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.

Case shapes are generated from each watch's published measurements — case width, lug-to-lug and thickness — not from manufacturer 3D models, so the proportions are accurate while the dial is generic.
