BENTHOS PROFESSIONAL
Built for Professionals. Inspired by Legends
After years of collaboration with professional, commercial, and sports divers around the world, Aquastar is proud to unveil the Benthos Professional, a modern dive watch built from the ground up, yet keeping the heritage of the iconic Benthos to meet the real-world demands of those who rely on their gear in the most unforgiving environments. The name. “Professional” reflects the purpose, the process, and the people behind its creation. The Benthos Professional, a contemporary reimagining of the legendary Benthos 500, first introduced in 1970. Revered by professional divers and worn by commercial and military divers around the world, the original Benthos 500 helped define the evolution of the modern dive watch. Today, Aquastar honors that legacy with a refined, purpose-built timepiece for the true dive watch purist.
The ICONIC dive watch from 1970
“With every Aquastar release, we try to look at the product cycles introduced by the brand’s original founder, Frederic Robert, and look ahead to what he might still be producing, had the brand never been paused during the quartz crisis,” says Aquastar’s spokesman. “We are proud to be both historians and custodians of this rich brand, using the new BENTHOS PRO to pay tribute to Aquastar’s influence and innovations in the world of undersea exploration,” he continues.

Questions
Before you order.
What is the Benthos Professional and how does it stand apart?
The Benthos Professional is the most rugged and durability-focused member of the Benthos family. It features a DLC (Diamond-Like Carbon) coating over the stainless-steel case, a treatment that dramatically increases scratch resistance and gives the watch a sleek black appearance. It is also the slimmest Benthos at just 13.7mm in height, despite offering 300 meters of water resistance.
What is DLC coating and why does it matter?
Diamond-Like Carbon (DLC) coating is an extremely hard surface treatment applied to metal. It creates a near-black matte or semi-gloss finish that is highly resistant to scratches from diving equipment, rocks, and daily wear. DLC is the preferred coating for professional tool watches used in demanding conditions.
What movement powers the Benthos Professional?
It uses the Swiss-made Sellita SW200-1 Elabore grade movement, a workhorse automatic caliber renowned for reliability and serviceability. The Elabore grade indicates it has been subjected to additional quality testing beyond the base specification.
How does the water resistance compare to other Benthos models?
Though the Benthos H1 has a deeper depth rating at 500 meters. The Benthos Professional is the most capable Benthos due to its HRV valve, 300 meter water resistance, and comfort on the wrist.
