Hermle 70961-740761 Precision Regulator 31-Day Seconds Pendulum Clock

Hermle 70961-740761 – Mechanical Precision Regulator

The Hermle 70961-740761 is far more than a conventional mechanical wall clock. This exceptional precision regulator combines traditional clockmaking with advanced materials and sophisticated bearing technology. Its mechanical precision movement provides a running time of approximately 31 days and therefore requires winding only about once a month.

The elegant black lacquer case with fine metal inlays, light-coloured dial, blued hands and visible precision mechanics create an exclusive yet distinctly contemporary appearance.

31-day movement – winding only once a month

Unlike conventional 8-day mechanical regulators, the Hermle 70961-740761 features a specially developed 31-day precision movement. Its column weight provides the energy required for approximately one month of operation.

The clock operates entirely without batteries or electricity and requires mechanical winding only about once a month.

Mechanical precision clock with deadbeat seconds

A particularly fascinating feature of this precision regulator is its deadbeat seconds indication. The escape wheel advances in 60 individual steps per minute, producing a clearly defined one-second progression.

The traditional Graham escapement incorporates synthetic ruby pallets. A solid anchor body and sophisticated bearing system underline the exceptional technical quality of the movement.

Synthetic ruby bearings and ball bearings

The precision movement uses high-quality synthetic ruby bearings together with ball bearings at important points within the wheel train. This sophisticated construction is designed to support the precise and reliable operation of the mechanical movement.

A maintaining-power system allows the movement to continue running while the clock is being wound.

Carbon pendulum rod and double-cylinder pendulum

The carbon pendulum rod combines low weight with excellent dimensional stability. Together with the sophisticated double-cylinder pendulum it forms an important part of the precision system and gives the clock its distinctive technical appearance.

Pendulum symmetry can be finely adjusted by means of a knurled adjustment nut on the pendulum rod.

Black lacquer case with metal inlays

The substantial black lacquer case provides a distinctly contemporary setting for the traditional mechanical movement. Fine metal inlays, the light-coloured dial and polished metal components create elegant contrasts.

Generous glazing provides an unobstructed view of the fascinating mechanics. With an impressive height of 133 cm, this precision regulator makes a striking statement in sophisticated modern homes, offices and representative interiors.
