I've been going through Mark Lovick's level 5 course on chronographs, and one of the demonstration movements is the Poljot 3133. I picked up a specimen, a "Poljot", to follow along. The watch arrived in running condition, and all chronograph functions worked.

Despite being hands down the most complex movement I've worked on (chronograph+calendar), disassembly was uneventful.

I did have the misfortune of clamping the movement in my movement holder crooked. This put pressure on the minute runner stem which gave it a slight bend. Luckily, there's no fouling, so I won't try to straighten it.

I don't have the fancy Bergeon tool to remove 3-spoked chronograph wheels, so I fashioned a tool out of scalpel blades. They were able to lever off the wheel without risking damage to the fourth wheel pivot.

Nothing to note, reassembly went well. TODO: document gotchas when oiling
