NL 400

Striking longcase clock with four months power reserve

Our striking longcase clock NL 400 is the epitome of a luxurious and highly innovative clock. It engages aficionados of the highest clockmaking and enthusiasts of special technical finesse. Its persuasively harmonious design and extremely robust construction promises durability for many generations. This beautiful, gilded movement runs for a full four months.

Precision and perfection

The prerequisite for extended power reserve is an extremely consistent power transmission. The perfection and precision of the wheel engagement was therefore carried to extremes.

Fourteen ball bearings, 9 ruby bearings and large ruby pallets on the lever also have an important role. Our well-established Naeschke 5-rod compensating pendulum is used to control the rate. The main reason permitting the extended power reserve is our newly developed Naeschke striking mechanism, which requires only 50% of the energy of conventional mechanisms.

You can observe the striking mechanism and its bell from the front. Many prototype experiments were tested before the final decision was made on the shape and hence the pure and crystal clear sound of the silver-bronze bell.

There is a choice of two versions of the NL 400: A large chapter ring with an inner second scale or a small chapter ring with an outer second scale which puts more emphasis on the form of the mechanism.
