The Aquastar Benthos Heritage II is a modern interpretation of one of the brand’s most iconic dive watches, blending the unmistakable character of the legendary 1970 Benthos 500 with contemporary proportions and modern Swiss watchmaking. Inspired by archival design sketches and developed in response to feedback from Aquastar enthusiasts, the Benthos Heritage II reimagines the historic tool watch for today’s collectors and divers while remaining faithful to its professional underwater heritage. Produced as a Limited Edition of just 500 pieces worldwide, it offers a rare opportunity to own a modern chapter in the Benthos story.

Crafted from premium 904L stainless steel, the case measures 40mm in diameter, 11.9mm in height and 44mm lug-to-lug, delivering a highly wearable profile without sacrificing the commanding presence that has defined the Benthos collection for decades. The distinctive dual-crown layout features a screw-down crown positioned at 2 o’clock and a manual helium release valve at 4 o’clock, creating a unique silhouette that pays homage to the watch’s deep-diving roots. A flat sapphire crystal with triple anti-reflective coating protects the dial, while a screw-down caseback helps ensure a professional-grade water resistance rating of 300 metres.

The semi-gloss black dial is designed for maximum legibility, featuring applied hour markers and hands filled with high-density Super-LumiNova. Surrounding the dial is a unidirectional 120-click rotating bezel with a black ceramic insert and luminous markings, providing precise elapsed-time tracking for diving and other timing applications. The clean no-date display reinforces the watch’s purposeful tool-watch character and vintage-inspired aesthetic.

Powering the Benthos Heritage II is the Swiss-made Sellita SW200-1 automatic movement. Operating at 28,800 vibrations per hour and fitted with 26 jewels, this proven calibre delivers reliable performance and a power reserve of approximately 38 hours. Renowned for its durability, serviceability and accuracy, it is a fitting choice for a watch designed to accompany adventures both above and below the surface.

Completing the watch is a genuine ISOfrane® rubber strap, widely regarded as one of the finest dive watch straps ever produced. Designed for exceptional comfort, flexibility and durability, the ISOfrane® strap enhances the Benthos Heritage II’s professional diving credentials while providing a secure and comfortable fit in any environment. Combining heritage-inspired design, modern engineering and true dive-watch capability, the Aquastar Benthos Heritage II is a compelling tribute to one of the most distinctive underwater instruments ever created.
