A Spring Drive GMT for the next generation
SBGE257 is one of three new Spring Drive GMT Sport models in a smaller 40.5mm form factor. It features green dial and bezel with a yellow GMT hand. The bezel is fixed in place and rendered in scratch-resistant ceramic with a 24-hour scale for tracking a second time zone. The hands and indexes are beautifully executed and feature ample LumiBrite paint for excellent nighttime visibility. Driving the watch is Caliber 9R66, a Spring Drive GMT where the local hour hand can jump to the appropriate hour without having to reset the watch. With 9R66 being rated to an accuracy rating of /-15 seconds a month, not having to reset the time allows the wearer to enjoy this unmatched precision.
