The Daniel Roth Perpetual Calendar Equation of Time was first introduced in 2004. And in 2007, they presented the new version with a 44 hour power reserve with 5 other complications. They are the perpetual calendar and displays of leap years, moon phases, equation of time and number of days of the month.
Its dial has a spiral guilloche motif with three overlapping counters of perpetual calendar display: a month window at 3, day of the week at 9, and a date and leap year display on double counter at 6. There is a unique counter between 2 and 3 that received a technical patent that indicates the number of days in the current month.
It further has a minute circle, a partial Roman numeral hours indication on mother-of-pearl plate (between 10 and 2) and the moon phase at 12.
Its case is made of polished platinum that is 44mm by 41mm. It uses an anti-reflective sapphire crystal and caseback. The water resistance is 30m with a date corrector pusher at 2,4,8, and 10. The central portion reveals the watch's inner workings. The movement is Automatic with Caliber DR114 that beats at 28,800 vph using 27 jewels. Another interesting feature to note is the solar time indicator located between 10 and 11 that shows the difference between mean solar time and true solar time.
