Aquastar Benthos H1 (New with box and papers) — USD 1,699 on eBay

The Benthos H1 represents Aquastar's ceramic-cased diving watch offering within the Benthos collection. This reference utilizes a 42mm ceramic case construction paired with a ceramic unidirectional diving bezel, positioning it as a contemporary interpretation of dive watch design principles. The 42mm ceramic case houses a manual-winding movement and features a black dial protected by sapphire crystal. Water resistance is rated to 100 meters. The watch is fitted with an ISOfrane rubber strap, providing a functional pairing with the ceramic case materials. The ceramic bezel operates in unidirectional rotation as standard for diving timepieces. Production of the Benthos H1 began in 2018 and continues to present day. This reference appeals to collectors seeking modern materials in diving watch construction, particularly those drawn to ceramic case technology and manual-winding movements. The combination of ceramic construction with rubber strap integration offers an alternative to traditional steel diving watches within Aquastar's contemporary lineup.
