Quick start guide Quick start guide

As you can see, the 46mm model is more compact than the 42mm model. This also results in the higher weight of the 46mm model, but you can see a little more at a glance on the 46mm’s 1.3 inches display. You can get the 46mm in black or silver, while the 42mm is available in rose-gold and midnight-black color. You’ll have to spend a little more to get the 46nm model.

The battery capacity of these two also differs, the 46mm model has a bigger 472mAh battery capacity than 270mAh of the 42mm model. This of course, despite the 46mm having a bigger display that requires more battery last longer than the 42mm. The video below confirms that the 46mm model has about 4 days long battery life compared to the 2 days of the 42mm.

Which is Better?

I can’t really say which is better between these two watches, the features and design are the same except for differences in sizes and battery life. It all depends on your wrist size. The 46mm which is a bit bulky looks cool on men, while the 42mm looks awesome on women especially the rose-gold color version. Personally, I really like the 46mm model, it looks bold and rugged.
