Samsung Galaxy Watch5: Three codenames and model numbers emerge, including a Pro version

GalaxyClub has unearthed details about the Galaxy Watch5 series, which is expected to debut this autumn. To recap, SamMobile alleged that Samsung would drop its 'Classic' branding with the Galaxy Watch5 series, having only introduced it last year with the Galaxy Watch4 Classic. In its place will be the Galaxy Watch5 Pro, which is rumoured to feature a 572 mAh battery. Currently, the Galaxy Watch4 series only offers up to a 361 mAh battery with 44 mm and 46 mm case sizes.

According to GalaxyClub, Samsung is developing three models, codenamed Heart-S, Heart-L and Heart-Pro. Reportedly, Heart-S correlates to the model number SM-R90X and should have a 40 mm or 42 mm case size. In comparison, GalaxyClub claims that Heart-L (SM-R91X) will have a 44 mm or 46 mm case size, making it a direct successor to the larger versions of the Galaxy Watch4 and Galaxy Watch4 Classic.

Meanwhile, Heart-Pro relates to SM-R92X, which GalaxyClub believes has one case size. For some reason, the website has not stated how large Heart-Pro or SM-R92X is, although it would be unusual for Samsung to release a smartwatch with a case size that exceeds 46 mm. Incidentally, the website stresses that the 'Pro' in SM-R92X's codename does not necessarily mean that it will launch under a 'Pro' moniker. Hence, SamMobile speculates that Samsung may sell Heart-Pro as the Galaxy Watch5 Ultra instead.
