After HYT put the horological world upside down with the introduction of their H1, and seduced all of us with this hydromechanical wonder, they are now launching the follow-up, named H2.The H2 was created in cooperation with Audemars Piguet’s technical wizards of the design subsidiary Renaud et Papi, who also collaborated with Gronefeld to create their magnificent One Hertz. The H2, which is limited to just 50 pieces, and is a logical evolution, after the H1. It exposes everything it’s got on the dial, for us to admire. Ad - Scroll to continue with article I think I’ve not seen so many enthusiastic reactions on any watch launch before, so now the path of the combinations of fluids and mechanics in a timepiece has been paved, it’s the difficult task of the H2 to seduce horological connoisseurs again. And that shouldn’t be a problem, because the H2 offers a surplus over the H1.All mechanics are fully visible, in full nudity exposed, and show how the bellows are activated every hour?by a system of feelers, cams and pistons, in order to indicate the correct hour. The bellows are positioned in a “V” and remind me of the mighty engine of a Harley Davidson…The positioning of the bellows in a V-shape optimises the integration of the interface which connects the watch mechanisms with the fluidic system. In comparison with the H1, it leaves more space so the the minute hand can be placed at center position and the balance spring resides on its black bridge, in the upper half of the dial.The entire system of feelers, cams, pistons and many gears can be seen and there is no dial to cover this mechanical beauty. The bridges are made in titanium, covered with black PVD coating. Because the bridges have been finished before the coating, some parts are obviously sand blasted and others have been satin finished or brushed before the coating. This offers an exquisite visual play of matte and glossy black parts. Other parts like gears, feelers, pistons and the hands have not been coated black and offer a nice contrast with the black bridges and main plate.Surrounding the dial is a sapphire chapter ring for the centrally positioned minute hand. When arrived at “30 minutes”, just before the normal 6 0’clock position, the minute hand jumps to avoid the bellow system.?At the sloping edge of the “dial” are the hour numerals printed, which make it easier to read the actual hours from the?hydro hour indicator.The H2 offers three additional indicators; a power reserve indicator,a temperature indicator and a HNR indicator. The latter is connected to the crown and tells the wearer in which position the crown is. The press release didn’t mention what the HNR stands for but let’s assume it is for setting the hours (H), neutral (N) and winding (R).Opposite is a temperature indicator, that tells the wearer whether the fluids are at the correct operation temperature. A logical indicator, as a fluid’s volume is always influenced by the temperature. So an indicator to let us know if the temperature is just right for the H2 to perfectly indicate the correct time, is a handy feature.The H2 offers a power reserve indicator that tells how much of the 192 hours (or 8 days) of power are left in the two main spring barrels. This is another improvement over the H1, which offers 65 hours of autonomy when fully wound. The power is indicated on the two barrels, which are visible on the back side of the watch.ConclusionNo word about the price, however I suspect it will be north of the $ 45k starting price of the H1, as it offers much more, both in visual pleasure (which has to be finished) as in functionality (8 days of power reserve).?All together the H2 looks like a brilliant follow-up of the H1 and since it’s limited to just 50 pieces, I think collectors will have to move fast in order to secure one of the pieces!Here some specifications and two cool sketches of the H2, which are exclusive for Monochrome to show you.?Collection: H2 –?Limited serie to 50 piecesCase:?Black DLC titanium with polished, microblasted and satin finishes Diameter: 48.8 mm Height: 17.9 mm Water-resistant to 50 metresFunctions: Retrograde fluidic hours Minutes with jumping hand at 30 minutes – Crown position indicator (H-N-R) Temperature indicatorMovement:?Mechanical with manual winding, exclusive HYT calibre 21,600 vib/h, 3 Hz, 28 jewels Titanium bridges with decorated microblasted Black PVD and titanium coloured satin-finished accents 192-hour (8-day) power reserveFor more info, please visit the HYT website.This article is written by Frank Geelen, executive editor for Monochrome Watches.
