The smart & stylish Calibre Hotblack Gravitas displays Hoptroff's characteristic rocking seconds on the top dial and perpetual date on the bottom dial. It's even smart enough to adjust for daylight saving time.
The Calibre Edition Hotblack Gravitas features the smart Calibre Hoptroff movement that is accurate to one second per year which makes it the most accurate watch in the world (except for our atomic watches). This is signified with a silvered glass on the back. To achieve this precision, each timepiece is individually subjected to an 8-hour temperature cycling ordeal while timing it against an atomic clock.
Currently compatible with iPhone and Android (download the free App now), and available in right-handed and left-handed versions. (Left-handed version has pushers on the left.)
In vertical-brushed, black-PVD coated stainless steel with a sapphire crystal, the Hotblack range is waterproof to 5 atmospheres, 1 second/year accuracy and a 5 year battery. The hands and hour digits are coated in superluminova. The calendar is perpetual and automatically adjusts for daylight saving and leap seconds. When you order, be sure to specify if you want the pushers on the right (for right-handed people) or the left (for left-handed people).
