This JDM-exclusive reference is widely codified by enthusiasts as the definitive successor to the discontinued Seiko SARB line. The NB1050-59A was engineered to fill a specific market vacuum, offering superior specifications at the value-centric price point the SARB once dominated.
Its primary technical advantage is the Cal. 9011, a slim, high-beat movement operating at 28,800 vph, which provides a visibly smoother sweep than its 3Hz predecessors. The 38mm stainless steel case and bracelet are also treated with Citizen's proprietary surface-hardening technology that offers exceptional scratch resistance. It stands as a superior technical proposition, fully earning its "SARB killer" moniker.
Founded in 1918 as the Shokosha Watch Research Institute, its core identity was solidified in 1976 with the invention of the world's first light-powered analog quartz watch. This technology evolved into Eco-Drive, a proprietary system that converts any light source into energy, effectively eliminating the need for battery replacements and becoming the brand's technological cornerstone.
Citizen is a true manufacture that produces its own components, including the robust and ubiquitous Miyota mechanical movements used by countless third-party brands. This industrial self-sufficiency allows Citizen to dominate the market for accessible, technologically advanced, and highly reliable timepieces.
