Let’s take a moment to appreciate the technical complexity of the new Grand Seiko Tentagraph SLGC001, the brand’s first fully mechanical chronograph that Grand Seiko developed entirely in-house. This vertical clutch column wheel chronograph has been rigorously tested and boasts a standard +5/-3 daily deviation. Its 9SC5 movement is a high-beat 5Hz movement accurate to one-tenth of a second and packs a three-day power reserve. Its dial is inspired by Mount Iwate, the mountain that faces in the Grand Seiko manufacture in Japan.

In this video, you’ll also get to see the new blue dial variant of the SLGA023 “Ushio” dive watch. Its 43.8mm ‘high-intensity’ titanium case houses the caliber 9RA5 that packs 120 hours of power reserve.

Up next is the hand-engraved 50-piece limited edition SBGZ009 in platinum. Its intricately handmade dial and meticulously grooved case are meant to evoke the white birch forests located at the eastern foot of the Kita-Yatsugatake Mountains.

Lastly, you’ll get to enjoy the new 100-piece limited edition SBGY026 “Hana-ikada,” which is powered by the Spring Drive caliber 9R31.
