Accurate and affordable starter watch!

Color: 2926 Silver Blue

I bought this watch solely out of curiosity. It's not as heavy as I'd like, but the weight reminds me of the Citizen Super Titanium (lovely watch but not a fan). So I gave it to my son. He loves this watch! He wears it all day at school and everywhere we go. He's done such a great job of maintaining it that I'm looking to get him more expensive ones for milestones. Honestly, this is a great starter watch and it's amazing how accurate it is!
