When I saw this I just had to get it, and this is coming from someone who already has one just like it from another company, so I got to side by side compare them both and these are my results.
It's a solid size about 6 inches tall and 6 inches wide, The outside feels solid durable and high quality. It makes almost no noise, and appears to work exactly the same as the other one I have only better. This one not only lights up more, but it also can be plugged into a power source via USB C, as someone who has what seems like endless products using USB C, this is probably the most convenient part, the other I have is AC Adapter powered and that requires an outlet or surge protector and that's so annoying because it limits where I can actually place it. This one also can use batteries, which is so awesome because it means a clean cordless look on your dresser or desk, or wherever you planned on placing this. I got the single one, because it was the only one available, I would say splurge and get the 3 watch one, because one it's worth it, and two you don't wanna mix metals so, a stainless watch, a gold watch, and a leather or mixed metal watch is the perfect trio for all occassions.
