Grand Seiko · Family: Sport Collection
The Grand Seiko Sport Collection 9F GMT SBGN027 is a 39mm steel travel watch with a black radial-pattern dial and a 24-hour graduated bezel, Grand Seiko's high-precision quartz proposal, distinct from the mechanical Spring Drive and Hi-Beat calibers already in Cazador's catalog. It runs the caliber 9F86 with a GMT function and ±10 seconds per year accuracy. Cazador has no verified price observations (n=0) for this reference as of today.

Grand Seiko organizes its mechanical and quartz catalog into several movement families with their own identity: Spring Drive (present in Cazador's SBGA211 'Snowflake' and SBGA413 'Shunbun'), mechanical Hi-Beat (SLGH005 'White Birch' and SBGH281), and the 9F quartz caliber, the brand's third technological path, developed to deliver the highest possible accuracy in a battery-powered movement.
The 9F caliber, introduced in 1993, incorporates a high-torque motor that advances the seconds hand in a single sweep rather than the typical 'tick' of a conventional quartz movement, along with a time-zone adjustment system that moves only the hour hand without stopping the seconds hand, preserving the internal chronometer's accuracy.
The SBGN027 belongs to the Sport Collection — Grand Seiko's range of sports and travel watches — and adds a GMT function to that 9F86 caliber via a 24-hour bezel divided into AM/PM sectors, built for travelers who need to read a second time zone at a glance. Its 200 meters of water resistance and 4,800 A/m magnetic resistance set it apart from the three Spring Drive/Hi-Beat references already in Cazador, all of them mechanical and without a second-time-zone function. [UNVERIFIED: we do not confirm the exact launch year of this specific reference within the Sport Collection].

A quartz caliber introduced in 1993, with a high-torque motor that sweeps the seconds hand in a single motion and a time-zone adjustment system that doesn't stop the seconds hand.
Those are mechanical calibers without a second-time-zone function; the SBGN027 is a high-precision quartz movement with a GMT function.
±10 seconds per year, well beyond the usual standard for a conventional quartz watch.
Yes, up to 20 bar (200 meters), a robust rating for a sports travel watch.
A fixed 24-hour graduated bezel with AM/PM sectors and an independent 24-hour hand, letting the wearer read a second time zone without disturbing local time.
