Powered by Seiko's iconic high tech quartz movement, 7C46. The 7 jeweled movement with extremely hi-torque tolerances and high efficiency enables the gears and pinions to move and turn the hands in perfect sync to the energy-pulse, with much less kinetic effort via the electronic step motors that power them. Thus making for a highly accurate and efficient full size quartz machine to perform strongly with much less resistance resulting in longer battery life.
SBBN047 sports a monobloc titanium case construction with a 49.4mm diameter and a thickness of 16.3mm. Additionally, the monobloc titanium case is treated with a black super-hard coating to ensure utmost durability. The monobloc, or one-piece construction negates the need for a case back, this results in the watch having an impressive water resistance of 1000m (ISO Certified).
Besides the unique aesthetic, the outer case, or commonly known as the shroud, protects the 120-click diving bezel from unintentional rotation and shock to the case during diving operations.
Features a hardened ceramic shroud treated with Seiko’s Super Black Dia-Shield coating for resistance against scratches.
The dial of the Prospex Professional 1000M Tuna Ref. SBBN047 retains the classic matte black dial with contrasting large white indices, being true to the first ever Tuna.Seiko also brought back the original brushed hands set found on the 1975 Tuna Ref. 6159-7010, replacing the “Prospex” hands that were found on the SBBN031/033.
The indices and hands are generously treated with Seiko’s famed Lumibite for a bright glow in dark lighting conditions.
