Orient Star Slim Skeleton RK-HJ0001S
The bezel is thinner than previous Orient Star models, making the dial appear larger. This design takes advantage of the large opening required to incorporate the movement from the dial side. Combined with the long, curved lugs and tapered case sides and back cover, it also creates a visually slimmer appearance. Automatic (Cal. F7F62). 24 jewels. 21,600 vph. Power reserve approximately 50 hours. Stainless steel (diameter 41.0 mm). Water resistant to 5 bar. Priced at 150,000 yen.

46 series F7-50 movement
This watch is equipped with the 46 series F7-50, the most advanced version of the 46 series movement. Its power reserve is approximately 10 hours longer than the existing movement. Its accuracy is the same as that of the mechanical moon phase, with a daily deviation of +15 to -5 seconds. The finish is also impeccable, with stripes on the rotor, a different decoration from perlage on the bridge, and diamond-cut chamfered edges. The three screws are blued steel.

Orient Star was founded in 1951. Since then, it has been a rare Japanese watch brand that has continued to produce mechanical watches without interruption to the present day. In June 2017, it merged with Seiko Epson and opened a new chapter as the new Orient Star. Its production system has been expanded and it has taken a more luxurious approach. The latest model for 2018 is packed with the brand's know-how and is full of the joy and pleasure of wearing.
