Product Overview

The Superocean Heritage B20 Automatic 46 pays tribute to Breitling’s rich diving heritage, reimagining the iconic 1950s Superocean for today’s discerning wearer. This timepiece masterfully blends vintage maritime inspiration with modern Swiss engineering, resulting in a watch that feels both nostalgic and thoroughly contemporary.

Encased in a robust 46mm stainless steel body, the watch commands attention without overwhelming the wrist, making it equally suited for underwater exploration and everyday sophistication.

Whether you’re descending into ocean depths or attending a business meeting, the Superocean Heritage B20 Automatic 46 delivers a confident, versatile presence.

Key Features

• Heritage-Inspired Design – Faithful to the original 1950s Superocean, this model retains classic design cues such as the distinctive triangular hour and minute hands, a legible dial with minimal distractions, and a balanced aesthetic that bridges sport and elegance. Modern refinements include updated materials and finishing techniques that enhance durability and visual appeal, ensuring the watch remains relevant across generations.
• Unidirectional Ceramic Bezel – Engineered for diver safety, the bezel rotates only in one direction to prevent accidental overestimation of remaining dive time. Crafted from polished ceramic, it resists scratches and fading, preserving its sleek appearance even after prolonged exposure to saltwater and sunlight. The 60-minute scale is clearly marked for intuitive readability during critical underwater moments.
• Breitling Manufacture Caliber B20 – Developed in-house and based on the proven Tudor Caliber MT5612, this automatic movement is officially certified as a chronometer by COSC (Contrôle Officiel Suisse des Chronomètres). It features a substantial power reserve and delivers consistent accuracy under a variety of conditions. The movement is visible through the exhibition caseback on select models, showcasing Breitling’s commitment to mechanical craftsmanship.
• 46mm Case Size – The generous 46mm diameter provides a bold, assertive profile that appeals to those who favor substantial timepieces. Despite its size, the case is proportioned for comfort, with carefully contoured lugs that allow it to sit securely on a range of wrist sizes. Its presence is commanding yet refined, suitable for both active wear and formal occasions.
• Unisex Appeal – Marketed as a unisex model, the Superocean Heritage B20 Automatic 46 transcends traditional gender boundaries. Its balanced design, neutral colorways, and versatile styling make it an attractive choice for anyone who values Swiss watchmaking excellence and diving-inspired functionality, regardless of gender.
