Galaxy Watch3 - Wi-Fi · 41mm — Frequently Asked Questions
Will the Samsung Galaxy Watch3 - Wi-Fi · 41mm fit my wrist?

What size band does the Samsung Galaxy Watch3 - Wi-Fi · 41mm 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 Galaxy Watch3 - Wi-Fi · 41mm battery last?
Samsung rates it at 2 days per charge in everyday use.
Is the Samsung Galaxy Watch3 - Wi-Fi · 41mm thick for a 41mm watch?
At 11.3mm, thinner than 70% of 41mm 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.
Should I get the 41mm or 45mm Galaxy Watch3?
The Galaxy Watch3 comes in 2 case sizes — 41mm, 45mm. Which one suits you depends on the flat width of your wrist rather than preference: the larger sizes need a wider wrist to sit inside the edge. Set your measurement in the size picker above and each variant reports its clearance in millimetres.
What other watches are the same size as the Samsung Galaxy Watch3 - Wi-Fi · 41mm?
TAG Heuer Carrera Chronograph Glass Box 41 Stainless Steel / Black, Zenith Defy Skyline Tourbillon Skeleton Rose Gold / Blue, Garmin Venu 4 - 41mm, Huawei Watch GT 6 - 41mm all sit within half a millimetre of the Samsung Galaxy Watch3 - Wi-Fi · 41mm's 41mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Samsung Galaxy Watch3 - Wi-Fi · 41mm?
42.5mm, against a 41mm 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.
