Samsung Gear S2 - 3G on a wrist

Put the Gear S2 - 3G on an arm sized to your own wrist and turn it — the view a photograph on a white background never gives you.

  • Samsung Gear S2 - 3G 44mm case, 51.8mm lug-to-lug, standing 13.4mm 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.

Gear S2 - 3G — Frequently Asked Questions

Will the Samsung Gear S2 - 3G fit my wrist?

The Samsung Gear S2 - 3G looks balanced on flat wrist widths of roughly 55–74mm (about 14.7–19.8cm circumference). Drag the slider above to check it against your own measurement.

What size band does the Samsung Gear S2 - 3G take?

20mm. Any 20mm strap fits, so you are not limited to Samsung's own bands — look for a quick-release fitting if you want to swap without tools.

How long does the Samsung Gear S2 - 3G battery last?

Samsung rates it at 2 days per charge in everyday use.

Is the Samsung Gear S2 - 3G thick for a 44mm watch?

At 13.4mm, thinner than 77% of 44mm watches, so it slides under a cuff more easily than most of its size. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.

What other watches are the same size as the Samsung Gear S2 - 3G?

Omega Seamaster Diver 300M Master Co-Axial 43.5 Milano Cortina 2026 Winter Olympics, TAG Heuer Carrera Chronograph Extreme Sport Titanium - Ceramic / Blue / Bracelet, Apple Watch Ultra 3, Amazfit Active 2 all sit within half a millimetre of the Samsung Gear S2 - 3G's 44mm case, so they cover the same amount of wrist.

What is the lug-to-lug of the Samsung Gear S2 - 3G?

51.8mm, against a 44mm case width. Lug-to-lug is the measurement that decides overhang: if it exceeds the flat width of your wrist, the lugs sit past the edge no matter how modest the case diameter looks.
