Henry Archer has expanded its Vesterhav collection with two new aventurine-dialed models, the Stellavir and the Aurelion. The Stellavir features a genuine green aventurine stone dial with a natural glittery texture, while the Aurelion utilizes the brand's signature black aventurine glass to mimic a starry night sky. Both watches depart from classic stainless steel by employing a warm blend of bronze and rose gold finishes for the cases, bracelets, hands, and markers. The new models maintain the collection's refined dimensions, featuring a 40mm case diameter, a 47mm lug-to-lug distance, and a slim profile of 10.45mm. Despite the thinness, the watches offer a substantial 20 ATM water resistance. They are powered by the Miyota 9019 Premium Series movement, which is visible through a sapphire caseback and features a custom gilt rotor decorated with a Côtes de Genève pattern. Additional technical specifications include a sapphire crystal with six layers of anti-reflective coating and the use of Super-LumiNova White10 BL Grade X1 for ice-blue legibility in low light. Practical features remain a priority, with each watch including a toolless micro-adjust system in the clasp providing 8mm of adjustment and a color-matched crown insert. The brand also confirmed that pre-orders for the Havstrøm Tachyon Purple, Vesterhav Viridian, and Tidevand Terra Enceladus Mirage are scheduled to ship toward the end of this month.
