Lenzkirch model 19 miniature regulator from my personal collection. This clock was used in the writing of my book. It is pictured on page 198. This clock is in mint condition and is 100% completely original as the day it left the factory in 1875, 135 years ago. It truly amazes me that these clock are still around in this condition. I have seen thousands of basket case clocks that require total restoration. One rarely finds a clock in this condition. I have had many miniature Lenzkirch clocks over the years. This is by far the best one I have ever owned. I need my head examined for selling it. The pictures do not do the clock justice. The case is burl walnut with satin banding inlay and ebony trim. The finish is original too. The 30 series miniature time only movement runs a fortnight (2 weeks) on a winding. The case is 57 CM long.
