Grand Seiko Automatic Hi Beat 36000 GMT Special White Gold SBGJ207

The 9S86 combines the 5 Hz Hi-Beat 36000 movement with a GMT function. It is self-winding with manual winding, runs at 36,000 vibrations per hour for about 55 hours, and adds a 24-hour hand with a quick time-difference correction linked to the calendar. The 9S86 dates from 2014, the year a Hi-Beat 36000 GMT won the Petite Aiguille prize at the GPHG.

The white gold case is 39.5 mm across and 13.9 mm thick, under a sapphire crystal. The yellow gold SBGJ208 and pink gold SBGJ210 are the same watch in other golds. In steel, the SBGJ217 keeps the silver dial and the SBGJ219 has a black one, both on straps; the SBGJ219 shares the 39.5 mm case. The bracelet GMTs, the steel SBGJ201 with its Mount Iwate dial and the titanium SBGJ211 and SBGJ213, measure 40 mm across and 14 mm thick.
