Since 1951, The Horolovar Company has been the trusted source for 400 day clock (or anniversary clock) suspension springs, suspension units, mainsprings, taper pins, and original clock parts. The Horolovar 400 Day Clock Repair Guide is the most accurate and complete reference available covering these fascinating and popular clocks. As the third owner of Horolovar, I am pleased and honored to carry on the tradition, helping people to repair, restore, and enjoy their anniversary clocks for years to come.
