UNIMATIC U4S-BRZ-ML
Price Tier N/A
The UNIMATIC x Massena LAB U4S-BRZ-ML is the first watch from UNIMATIC, along with its companion piece, the U4S-BRZ-MLL , to feature a bronze case. The U4S-BRZ-ML takes its inspiration from the tales of the French novelist Jules Verne, such as Journey to the Center of the Earth and especially Twenty Thousand Leagues Under the Seas. These stories , examples of Victorian-era science fiction dating to the nineteenth century, embody the exciting, adventurous, early days of diving. The UNIMATIC x Massena LAB U4S-BRZ-ML, features a matte dial in deep olive with a warm, bronze-tone signature, and rich plots of pale yellow Super-LumiNova for its hour markers. Its hands, displaying hours; minutes; and seconds, are also luminous. Its bronze case is brushed circularly around its bezel, and diagonally on its lugs for visual interest. On its titanium case back: a detailed engraving of a cunning octopus. Housed inside the 40mm bronze case is the automatic, Swiss-made, Sellita caliber SW200-1, with 28800bph, a power reserve of 38 hours, and 26 jewels. Water resistance is 300m. Sapphire crystal with anti-reflective coating. Each watch is delivered with two straps for added versatility: a TPU strap in olive green with a bronze buckle, and a distressed leather strap, also with a bronze buckle. U4S-BRZ-ML is a limited-edition of 400 pieces. Bronze develops a unique patina when exposed to oxygen. Color changes to the bronze case of the U4S-BRZ-ML are to be expected and will vary depending on the region of the world where the watch is worn. This patina is natural and is considered to be a feature of the design. Free shipping. Limit of one watch per household.
