Samsung's Galaxy Watch 5 Pro is tethering on the verge of being too big. At 45mm, the Watch 5 Pro may be the right size for me but may not be for other potential customers. Some people I’ve talked to say that the Watch 5 Pro is a tad too big for their liking. Some may describe the Watch 5 Pro as “big and bulky” but it’s actually “smaller” than the fitness watches - from the likes of Garmin - it is competing against. The Watch 5 Pro will appeal to those with medium-sized wrists or those who dig the oversized look.
