The new 2023 editions of the HM9 SV are each limited to just five pieces, just like their 2021 predecessors. One has a yellow gold frame, with the movement coated in a green PVD finish, and the other features a white gold frame, with the movement coated in blue PVD. The overarching design is exactly the same as previous versions of the HM9, with the central “hull” running down the center of the watch, flanked by each balance wheel encased in prominent sapphire bubbles. If you observe the watch on your wrist in the way you would a typical timepiece, you’ll see the entire mechanism on display, with both balances in motion. To actually read the time, you’d tilt your wrist toward the sky, as the dial is located at the end of that long middle section. The HM9 is essentially laid out like a driver’s watch, meant to be easily readable while your hand is on the wheel.
