Is the Garmin Venu 4 - 45mm thick for a 45mm watch?
At 12mm, thinner than 76% of 45mm 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 Venu 4?
The Venu 4 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 Garmin Venu 4 - 45mm?
OnePlus Watch Lite, Oppo Watch S, Google Pixel Watch 4 - 45mm, Tissot T-Race Chronograph PVD / Black / Rubber all sit within half a millimetre of the Garmin Venu 4 - 45mm's 45mm case, so they cover the same amount of wrist.
