Inspired by the white birch bark found near the Shizukuishi studio Introducing the first Grand Seiko 10-beat manual winding movement in 50 years New dial pattern inspired by the horizontal patterns on white birch tree bark Housed in a 45mm Brilliant Hard Titanium case with a black crocodile leather strap Powered by the new in-house 9SA4 10 beat manual-winding calibre with an 80-hour power reserve POWERED BY A NEW ICON In 1968, the 45GS launched as the first Grand Seiko with a 10-beat manual winding movement. This new 2024 Birch Bark model introduces the first Grand Seiko 10-beat manual winding movement in 50 years - the in-house built 9SA4. This Birch Bark model presents a new dial finish, inspired by the horizontal patterns on white birch tree bark found in the forests near Shizukuishi studio where all Grand Seiko mechanical watches are crafted. INSPIRED BY WHITE BIRCH TREE BARK This striking model is characterised by its silver dial, with a distinct horizontal pattern and a blue seconds hand. Less than 10mm in depth, the slender 45mm case is crafted from Brilliant Hard Titanium, an alloy which is brighter than traditional titanium for a beautiful, lightweight timepiece that is also highly resistant to corrosion and scratches. Visible through the transparent case back, the new in-house 9SA4 10 beat manual-winding calibre powers the watch with the ultimate precision, offering an 80-hour power reserve. Based on the 9SA5 movement, the calibre features a newly designed manual-winding movement, a new bridge shape, and a new wheel finish. A black crocodile leather strap completes the aesthetic.
