Poljot Chronograph, Cal. 3133
(Made in Russia)

See? This is how a WIS looks at a watch!

A WIS will always see the picture of a damage in maximal magnification! I really do not like the feeling to having "butchered" a really nice NOS Poljot Chronograph. The only consolation is that I was really careful and increased opening pressure slowly and experimented with ALL MY case openers. Also used ALL MY KNIVES. I must have used 20 tools and then realized I would only destroy the case back further. I then decided to wear the watch and was so happy to see that it was running at ca. +15 seconds and that it would not need service soon. But still, a very unpleasant experience.
I asked fellow Poljot collectors on the forum and the result was: tolerance problem. Some open easily, some don't. Oh well, at least I know this is most likely to withstand the tropical climate here. I try to think positive, very hard ;)
