Grand Seiko Watch Sport Spring Drive GMT – Black

Grand Seiko Watch Spring Drive GMT. SBGE253G. Delivering unparalleled functionality for a modern-day globetrotter, the Grand Seiko Sport Spring Drive GMT watch maintains the traditional shine of a classic Grand Seiko watch with a formidable GMT complication at its centre. As part of their iconic Sport Collection, the Grand Seiko GMT watch delivers a luxurious aesthetic inclusive of a 40.5mm by 14.7mm stainless steel exterior, a 200 metre water resistant screw in crown, screw down case back decorated with the legendary Grand Seiko lion emblem and dual curved sapphire crystal glass, a material renowned for its scratch resistance and ultra-legible anti-reflective coating. Housed within the tough exterior of the Grand Seiko Sport GMT watch is Calibre 9R66 Spring Drive movement, an in-house automatic movement that combines the motive force of a mainspring with the high precision of a quartz watch. Working alongside the high-tech black bezel with 24 hour scale, the brightly-coloured red GMT hand allows international travellers to ensure the accuracy of the time shown is not compromised when the time zone is changed. Alongside a remarkable accuracy of +/- 1 second per day and 30 jewels, the movement delivers central hands for hours, minutes and seconds, a box shaped date window at 4 o’clock and a power reserve indicator for up to 72 hours. For optimal legibility of the time, the hands and indexes are highlighted in glow in the dark Lumibrite.
