Arnold & Son DBS watch features two major complications in one watch

Andrea Divirgilio / September 24, 2012

Belonging to a select group of Swiss watchmaking companies entitled to calls themselves a manufacture, a French term reserved exclusively for watch manufacturers who develop and produce their own movements in-house, Arnold & Son as a watch brand is known for its impressive collection of calibers with a complete range of sophisticated complications. This Swiss luxury watchmaker has now unveiled the Instrument DBS Equation Sidereal, which is actually a tribute to two iconic watches, the Nos. 1 and 2, originally crafted by John Roger Arnold, a renowned inventor and watchmaker, that displays the sidereal time and mean solar on two separate subdials. Conceived, designed and crafted in-house, this masterly engineered watch featuring newly developed manufacture A&S1311 calibre, has been named after its two major complications, the ‘double balance’ and ‘sidereal time.’

The DBS Equation Sidereal boasts a symmetrical arrangement of the barrels, gear trains, and bridges, and the perfect symmetry is then continued on the dial side, where a harmonious circle is created by two adjacent balance cocks. The left subdial displays the Sidereal time, and the right subdial shows the mean solar time.

Additionally, a subdial at 12 o’clock indicates the equation of both times on a 24-hour basis, allowing the user not only to measure the difference between sidereal time and mean solar time, but also to make-sure whether the time in both zones is p.m. or a.m.

Scientifically, astronomers uses the ‘Sidereal time’, a special timekeeping system that helps them track the direction which is needed to point a telescope at a particular star.
