Belonging to the category of ‘romantic complications,’ like the classic and iconic moon phase display, it is a complication that is impressive to behold and yet is not likely to be useful on a daily basis. Due to the ever changing orientation of the Earth, tilting on its axis as it travels along an elliptical path around the sun, a day is rarely exactly 24 hours long. This deviation is almost never taken into account in regular civilian life, despite the fact that a day can be up to 15 minutes longer or shorter depending on the time of year. An Equation of Time indicator solves this issue, being able to display the real time difference between civilian and true solar time, and in the case of the present watch is indicated on an outer ring graduated to +/- 15 minutes. In 2005, Daniel Roth decided to incorporate this benchmark complication within their signature double ellipse case. The technological prowess housed inside is beautifully complimented by the complex dial design, with the top section housing a luxurious mother-of-pearl section, skeletonised middle section to showcase the complexity within, and finally a guilloché section to round off a watch that is intricate both inside and out.
