Gruppo Gamma Vanguard Mk IV
Young watch brand Gruppo Gamma presents Mk IV, the newest version of its popular Vanguard collection. Introduced in 2014, the Vanguard draws its inspiration from the legendary Rolex Ref. 6152 watch and features a retro-inspired design infused with contemporary touches. The watch case of Vanguard model is made of surgical grade stainless steel, fitted with double-domed sapphire crystal and engineered to achieve a depth rating of 200 m/ 660 ft.
Its newest generation, the Mk IV features the SuperSandwich™ dial, filled to the brim with Swiss Superluminova to achieve the best darkness visibility ever on a Gruppo Gamma timepiece. Also for the first time ever, the rotor – visible through the sapphire display caseback – is signed, and the crown guard is now constructed as a separate piece and bolted onto the case. In addition, a newly-designed mechanism is used for the unidirectional 120-click bezel.
The first Mk IV models the brand is planning to release are A-04, A-04D (Both without date) and A-05(with date function). All models in this release are powered by Seiko SII’s NH35, a self-winding mechanical calibre from Japan that’s well-known for its dependability. The full kit includes a vintage Italian leather strap in Gruppo Gamma’s signature leather color, and a military green canvas strap unique to the Vanguard. Gruppo Gamma is currently accepting pre-orders at its website with prices start from USD399.
