Opus Secunda M 130
HIGHLIGHTS
- Case with anti-reflective mineral glass
- Elegant and flat with a depth of only 12cm
- Three-dimensional hand-painted moon phase
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 centimetres 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.

CALCULATION OF THE MOON PHASE DISPLAY
Opus Secunda M 130
PRECISION SECONDS PENDULUM CLOCK IN A NEW CASE
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 skeletonised 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.
The operating time of the OPUS SECUNDA M 130 is 30 days.
