Hysek IO 42 mm Power Reserve
With its three hands, date, and power reserve, the IO 42 mm Power Reserve model embodies Hysek’s take on classical watchmaking.
Hysek’s IO collection comprises round, classical-style pieces, featuring traditional watch making’s most emblematic complications: date, moon phase, and chronograph. The new IO 42 mm is the only model to include a power reserve. Formerly available atop a black dial, the piece now has a more contemporary feel thanks to a brighter, livelier electric blue livery.
The new-look sun-brushed dial has polished rhodium-plated hands and appliques that reflect light in all directions. Meanwhile the date display at 12 o’clock features large windows, making it very readable. The time and date are set using a single crown at 3 o’clock, enhanced with a black disc bearing a raised “H” for Hysek.
The power reserve is deployed at 6 o’clock. An imposing yet precise hand with a semi-circular movement displays the watch’s remaining power reserve over 42 hours. Around it, every aspect of the 42 mm steel case is exactly right down to the tiniest detail, with a refined blend of satin and polished parts. The signature lugs that are now one of Hysek’s hallmarks are there, along with another – the distinctive presence of only the 1, 5, 7 and 11 Arabic numeral applique hour markers.
The timepiece is powered by a Swiss Made automatic movement with 22 jewels, visible through the sapphire caseback. The movement has been developed in line with traditional watchmaking style codes, including a Côtes de Genève finish and blued screws. Hysek has opted for a high-frequency caliberboasting 28,800 vibrations per hour, guaranteeing perfect precision. The new IO 42mm Power Reserve sports a blue leather strap.
