Which is The Difference?Both sizes have the same appearance, the same 316L stainless steel frame paired with silicone straps. You also get a physical rotating bezel, touch-sensitive screen, and two physical buttons on both units. And in terms of activity tracking features, both sizes are the same.
Both the 42mm and 46mm also come with a 4GB storage capacity that allows for onboard music storage. You also get an NFC chip on both sizes that enable Samsung Pay. And there is a microphone and speaker on these two units that allows you to make and receive calls directly from the watch. Note that the LTE model of both sizes is a standalone smartwatch that can make and receive calls independent of a smartphone.
Now let’s take a look at the differences between the 42mm and 46mm units of the Galaxy Watch.
- The 42mm unit is more compact
The first difference you will spot between the 46mm and 42mm units is the size. The 42mm is more compact and weighs a little less than the 46mm unit. From my experience, the 46mm unit is quite heavy and bulky. Meanwhile, while the 42mm unit has a 20mm strap, the 46mm unit has a 22mm strap size.
- The 46mm unit has a bigger display
- The available colors are different
- The 46mm unit has a longer battery life
- The 42mm unit is cheaper
As a result of the bigger case size, the 46mm unit has a bigger display than the 42mm unit. It has a 1.3 inches display size compared to the 1.2 inches of the 42mm unit.
While the 46mm unit is available in black and silver colors, the 42mm unit is available in silver and rose-gold colors. The latter color is most likely a feminine color, and thus, makes the 42mm unit a better choice for women.
The 46mm unit comes with a higher battery capacity than the 42mm unit, thanks to its bigger case size. As a result, I get about 3-4 days on average with the 46mm unit, while the 42mm averages about 2 days. In fact, compared to the 46mm unit of the Galaxy Watch, the Galaxy Watch 4 Classic (46mm) has a shorter battery life of about 2 days despite having almost the same case size and a higher-end chip.
As a result of the bigger display size and longer battery life, the 46mm unit is priced a little higher.
Which Size is Right For You?
Since we all have different wrist sizes, the right size for Mr. A might be too big for Mr. B. In that regard, you need to take a measurement of the width of your wrist and then compare it to the size of the watch. That way, you get a near-perfect fit on your wrist which is the idea behind the different sizes.
In other words, the 46mm unit will make a perfect fit for men and individuals with a moderate to fat wrist size, while the 42mm unit will be suitable for women.
