From Russia with love...and sand!


Recommended Posts

This is the second Poljot 3133 Chronograph I received, from which I already took the balance wheel to temporarily fix the Sturmanskie on the other thread (when the new balance wheel arrives I will swap them again).

This one looks pretty sad, the case gold plating was badly worn of and the movement, without the stem, makes me think the watch took a plunge in the Baltic Sea, so much sand is inside!

The order was inverted by the phone... But you get the idea. All the parts were cleaned and inspected. I found no broken jewel nor bent pivot, only a lot of sand and dirt.

The chronograph start/stop lever was damaged though, so that will need to be sourced. A pic I took before disassembling the movement shows the broken off tip of the lever, where the pusher should touch it.

    • Just a note for those who come searching for information on this topic in the future.  I did eventually find the Mark's video on how to replace these springs, as someone observed, he does in fact make the replacement look easy.  (It actually is relatively easy once you have the knack of it.) If you're enrolled in one of Mark's online courses, the demonstration of how to replace this spring is in the Bonus Videos section of his course site, and is called "C2B1 – Sea-Gull Style Shock Springs".
    • If the metal was twice as thick, it wouldn't snap so easily.  The thickness is governed by the space available so you can't use thicker metal.  If you glued two pieces together, the likelihood of snapping would be reduced.  That's my theory anyway, could be wrong. 
    • there are various approaches to learning watch repair. A lot of people want to jump right in and every single watches something to be repaired restored. But other times like this it's disposable it's here for you to learn and when you're through learning you throw it away. yes you definitely should try this you have a learning movement you need to learn and the best way to learn is by doing something.
    • Sorry, the friction will be so great that the wheel will barely turn, if the movement will start at all, the amplitude will be verry lo.
    • If I can’t re-pivot the wheel, the logical thing to do is to descend the pivot hole.  Plan is to either stick a suitably sized hole jewel (from a barrel bridge or something) or fashion a blob of epoxy on the underside of the escape wheel cock so the wheel sits on its one pivot on the base plate and the staff with the broken off pivot (which I’ll polish as best as I can) becomes the upper pivot. As long as it doesn’t foul the 4th wheel it should work? I know it’s a bodge job, and if this were a rare movement, or belonged to someone else I would not do this. I’m just interested to see if I can get the thing to run.
