Mechanica M4

The Mechanica M4 is a precision pendulum clock with all the quality features of its illustrious models. Some of its characteristic hallmarks include a temperature-compensated Invar pendulum, hardened steel pinions and milled, gold-plated gear wheels.

A detailed assembly manual entitled “The Clock Book” not only guides you step by step towards a truly rewarding sense of achievement, but also introduces the owner to the technical workings of the Mechanica M4. Optionally, an experienced Erwin Sattler clockmaker can assemble your kit for you.

Customisation can be achieved with various upgrade kits: These allow the customer to transform the dial of their Mechanica M4 into a regulator dial and further enhance it if they wish by adding hand-domed and polished hands. The upgrade kits on offer also include a ball-bearing rope pulley, polished screws and a double cylinder pendulum.
