Kern Miniature 400 Day Clock, Nickel Plated

May 11, 2010 | By | 3 Replies More

This Kern miniature 400 day clock has nickel-plated base, pendulum, pillars, platform and bezel. The suspension bracket and pendulum bracket are also nickel-plated, the movement plates are not. It is a newer clock (the owner remembers buying it in Germany around 1972 or 1973) and has a very thin base that warps easily. It is 7 1/4 inches tall without the dome.

I polished the pivots and replaced the suspension spring. It uses a .0023 inch thick suspension spring, unit 12F (but about 1/8 inch longer). Horolovar back plate no. 1406G.

    I have a small kern 400 day anniversary clock, thats not going. had it at the clock repairers for just on 12 months could not fix, it ran fine for an hour or so ,then raced ahead three to four hours then ran good for a while. then repeated its time racing. so they put it back together how it was when I took it ti them. sitting on mantle not going what a shame. could you tell me of anyone that might be able to repair this clock in toowoomba or brisbane qld.

    The following place sells suspension springs:

    If it is the miniature clock, it probably uses a .0023″ spring. If it is the standard size (about 12″ tall) it probably uses a 0.0036″ spring.
