Samsung's new Galaxy Watch 6 and Watch 6 Classic debuted last week during the company's Unpacked event, and they will be joining the Galaxy Watch 5 Pro, which remains available. The three watches occupy different parts of the pricing scale, with the higher-end Watch 5 Pro including additional sports modes that could be particularly helpful for more active wearers.

Samsung's Galaxy Watch 6 starts at $300 (£289, AU$549) for the smaller 40mm size and $330 (£319, AU$599) for the larger 44mm size. The step-up Galaxy Watch 6 Classic -- which includes a physical, rotating bezel -- starts at $400 (£369, AU$699) for its 44mm model and $430 (£399, AU$749) for the 47mm model. The Galaxy Watch 5 Pro occupies the high end of this list, at $450 (£429, AU$799) for its 45mm size.

Both Galaxy Watch 6 editions will ship with Google's Wear OS 4, and the Watch 5 Pro will be getting an update to that software version. In addition to the various size differences between each of the watches, the batteries range from 300 mAh for the smaller Galaxy Watch 6 and 6 Classic, 425 mAh for the larger watches and 590 mAh for the Watch 5 Pro. We'll have to test the Galaxy Watch 6 to see how their batteries hold up, but my colleague Lexy Savvides found in her Galaxy Watch 5 Pro review that the battery would usually last about two-and-a-half days.

We've outlined the specs for each of these watches side by side in this comparison table, so you can further check out the differences between the Galaxy Watch 6, Galaxy Watch 6 Classic and Galaxy Watch 5 Pro.
