Who could ask for more? Another first for the engineers at Poljot, this chronograph has become a sought-after grail for many 3133 collectors.
Like-new from '92!
Despite no remnants of lubricants, this nos movement toped out at 300 degrees of amplitude on my timegrapher.
The brass balance wheel would be replaced by the end of 1992 by a new silver coloured alloy that, presumably, expanded/contracted to a lesser degree with changes in temperature, and therefore increased accuracy.
A mint-condition casing and Sturmanskie case back from early-1992.
