Movement: It is powered by the in-house Seiko automatic Caliber 4R34, which is a 24-jewel movement that beats at 21,600 vibrations per hour and has a power reserve of approximately 41 hours. It also supports manual winding.
Design: The watch case and five-link jubilee-style bracelet design are inspired by the classic Seiko SKX series. It features a magnified date calendar (cyclops lens) and a transparent case back.
GMT Function: This is the first Seiko 5 Sports watch to feature a GMT function, allowing the tracking of two time zones simultaneously. The two-tone bezel helps distinguish between night and day hours at a glance.
