The Eins 4.EIN-M301-MOD-S, seen from the bench

The Defakto Eins Modular Black is a minimalist timepiece featuring essential design with Bauhaus philosophy. Its integrated bracelet architecture forms a single functional sculpture where case and strap merge as one. Custom-made strap work by Atelier Casati Milano respects the rigorous proportions of the original German independent watchmaking project, using premium leathers from private reserves.
