Oris Big Crown 43mm 01 113 7800 4057-07 8 21 06

The Oris Big Crown Calibre 113 Men’s Hand-Wound Watch Reference 01 113 7800 4057-07 8 21 06 is a powerful statement of independent Swiss watchmaking, combining one of Oris’ most iconic designs with a high-performance in-house mechanical movement.

Crafted in Switzerland and backed by over a century of horological heritage, this luxury men’s watch showcases Oris’ commitment to precision engineering, innovation, and exceptional manufacturing quality. The signature Big Crown design, originally created for aviators, delivers bold presence and functional clarity, while the finely finished stainless steel case reflects the brand’s dedication to durability and refined craftsmanship.

At its heart beats the impressive Oris Calibre 113, a hand-wound in-house movement developed to demonstrate true mechanical excellence. This Swiss-made manual wind calibre offers an extraordinary 10-day power reserve, complemented by a non-linear power reserve indicator that visually tracks the remaining energy with precision.

Adding further distinction is the practical 52-week “business calendar” complication, designed for modern professionals who value both form and function. Visible through the case back, the movement highlights Oris’ independent spirit and expertise in creating advanced mechanical watches that stand apart in the world of Swiss luxury timepieces.

What we love about the Oris Big Crown Calibre 113 Men’s Hand-Wound Watch Reference 01 113 7800 4057-07 8 21 06 is how it unites heritage aviation design with serious mechanical capability. Its commanding 10-day power reserve, innovative business calendar, and unmistakable Big Crown styling make it a confident, masculine timepiece for collectors who appreciate authentic Swiss craftsmanship and the enduring appeal of true in-house watchmaking innovation.
