Experts agree that Horolovar suspension springs are superior to any other suspension springs on the market. Not only do they compensate for variations in temperature, only Horolovar's unique manufacturing and quality control processes can be relied on to produce accurately sized, long lasting suspension springs.

Only Horolovar brand suspension units are equipped with a Horolovar suspension spring. They are carefully assembled in single purpose jigs. The position of the blocks and fork, and the strength of the spring are guaranteed to be accurate in every respect for the clock and model specified in The Horolovar 400 Day Clock Repair Guide.

Horolovar blocks and forks don't just look similar to the original German clockmakers' blocks and forks, but have been carefully designed and manufactured to original specifications and tolerances, far surpassing in quality any others available today.

Horolovar mainsprings are made of the finest grade steel, tempered evenly throughout the entire length. They are designed to provide the right amount of power for your 400 day clock. Each mainspring is coiled to a diameter small enough to slide into the barrel easily - no expensive mainspring winder needed!
