Breitling Superocean Heritage B31 automatic green dial rubber strap 40 mm

A diver born for style, calibrated for action

Since 1957, the Superocean Heritage has been designed for those who see a diving watch as more than just a tool: an object with character and a distinctive style. The 2025 version pays tribute to this spirit with a refined design, modernized details and, above all, a movement that is now 100% manufactured in-house. In this 40 mm rubber version, the Superocean asserts its active, flexible and dynamic personality—a timepiece perfectly calibrated for modern everyday life.

Less bulky than the 44 or 42 mm versions, but just as charismatic, it is positioned as a high-end option, equally at home in motion or at rest, between nature and the city, between performance and elegance.

The model: a green wave on the wrist

The AB3110361L1S1 features a bright, rich green sunray dial, textured by the changing reflections of natural light. It is highlighted by a shiny, smooth, scratch-resistant green ceramic unidirectional rotating bezel. The collection's signature hands—arrow for the hours, spear for the minutes—are enhanced with Super-LumiNova®, as are the applied hour markers, to ensure perfect readability.

The textured green rubber strap, supple, comfortable, and durable, anchors the watch in active modernity. Its “technical fabric” texture and smooth fit make it suitable for sports, nautical, or urban use. Water-resistant to 200 meters and protected by a domed sapphire crystal with double anti-reflective coating, the watch remains true to its diving heritage without compromising on style.

The B31 caliber: Breitling's three-hand in-house movement

The B31 caliber embodies the revival of automatic movement at Breitling. This in-house movement offers a power reserve of 78 hours, bidirectional winding, and COSC chronometer certification. Its frequency of 28,800 vibrations per hour guarantees optimal stability, while its robust construction makes it a durable and reliable engine, perfectly suited for everyday use.

Visible through the sapphire caseback, the B31 is a fine demonstration of Breitling's mechanical advancement in its three-hand models. In this 40 mm version, it adds real watchmaking depth to an already highly accomplished design.
