With a superb eye for detail, @HoroMarioBro showcases superb macro imagery and slo-motion videos which draw fellow enthusiasts deep into his world of Haute Horlogerie.

During the process of collecting watches, @HoroMarioBro discovered the incredible work of Armin Strom as well as the strong focus on Independent watchmaking by Oster Jewelers.
