Grand Seiko Hi-Beat 36000 GMT 44GS 55th Anniversary

Hi-Beat 36000 GMT 44GS 55th Anniversary is a wristwatch from the Grand Seiko brand in the “Grand Seiko Heritage Collection” series.

Presented in December 2021, this limited edition model celebrates 55 years of Grand Seiko style with a new hi-beat GMT creation.

The watch's design is inspired by the Grand Seiko style defined 1967 with the famous Grand Seiko 44GS.

The watch is powered by the automatic-hi-beat-manufacture caliber Cal. 9S86, which achieves an accuracy of -3 to +5 seconds per day and a long power reserve of 55 hours.

In 2014, a watch with the same caliber won the “Petite Aiguille” prize at the Grand Prix d'Horlogerie de Genève, bringing the caliber and the Grand Seiko style to a wider audience than ever before.
