The 46mm Watch 5 Pro is tipped to come in Phantom Black and Silver colours. Samsung is set to deliver sapphire glass and a titanium build on the Galaxy Watch 5 Pro. A titanium build is not particularly common for most smartwatches, but it would certainly make for a premium build, earlier reports said. The benefit of sapphire glass is that it is essentially scratch-proof, giving smartwatches that use the material excellent durability. The company may bring Galaxy Watch 5 with a thermometer.
