Opus Secunda M 130

PRECISION SECONDS PENDULUM CLOCK IN A NEW CASE The steady swing of the one-second pendulum and the quiet ticking of this high-precision timepiece convey a sublime serenity. The new Opus Secunda M 130 hangs on the wall like a painting, elegant and flat. Despite its complex inner workings, it only takes up a modest 12 cm ( ≈ 4.72 in) on the wall. The use of never-before-seen technical refinements makes the Erwin Sattler manufacture calibre 1736 the flattest ever precision movement. Each movement is engraved with an individual number. The anti-reflective mineral glass allows a completely unhindered look at the dial, hands, movement and pendulum. The U-shaped glazing is cut and glued on a mitre in a single piece by expert craftsmen. The rims and base are decorated with metal inlays. And there is no need for a locking hook, thanks to the discreet magnetic catch on the door. The elegant design of the Opus Secunda M 130 is dominated by a skeletonized dial, which allows a glimpse of the gold-plated gear wheels. The spherical moon in a funnel also gives the timepiece a unique look. It is hand-painted in the manufacture with the highest level of attention to detail. This seconds pendulum clock is also an extremely accurate timepiece, maintaining a maximum accuracy deviation of three to four seconds per month. A weight running down the side allows a power reserve of 30 days. The fine gear wheel toothing and the use of ball or jewel bearings for all rotating parts ensure a working life lasting for many generations. The slight temperature-induced changes in the length of the Super Invar pendulum rod are counterbalanced by a precisely calculated, compensation tube. To prevent bigger accuracy deviations due to fluctuations in air pressure, a double aneroid capsule is added to the pendulum. Polite restraint and modern elegance are combined in a compellingly beautiful precision timepiece that takes up all the space it requires without being intrusive.
