The OHI4 GREEN HEIGHTS Calibre - First Edition was designed by SNGLRTY  in collaboration with renowned Swiss watch engineers. The unique reverse gear mechanism that slows and reverses the movement of the minute disc is the feature of all OHI Calibres, the OHI4 Calibre also elevates the date complication so an enlarged date is displayed at the six position. The Calibre OHI4 features 42 hours of power reserve, is accurate to +/- 4 sec/day, the balance wheel operates at 28'800 A/h. The movement features 25 jewels, is rhodium coated and decorated with Perlage circular graining on the base plate and straight Côtes de Genève on rotor.

This precision mechanical watch embraces the concept of "Seeing time differently". On the SNGLRTY Calibre OHI4 GREEN HEIGHTS - First Edition, the hours and minutes can be read in one place on the dial thanks to the ingenious patented hour display.
