Designed entirely in-house, this movement was engineered for long-term ownership, featuring enhanced resistance to magnetism, extended service intervals, and exceptional mechanical autonomy with its five-day power reserve. The Aquis Date Calibre 400 combines this advanced movement with Oris’ proven dive-watch architecture: a solid stainless steel case, ceramic bezel, and professional 300-meter water resistance. The blue dial offers excellent legibility, while the overall design remains clean, purposeful, and unmistakably modern. This model represents Oris at its strongest—independent, innovative, and focused on real performance rather than marketing hype. A true contemporary classic and a cornerstone piece for collectors seeking a serious Swiss dive watch with genuine in-house credentials.
