I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
