After some days of silence, i'm beginning to post again on the forum.
In the meantime, several watches landed in my home. This is one of them.
The Poljot/Moscow Classic Aeronavigator (read here about the "Moscow Classic" brand) is a real beast - 47 mm of diameter, and VERY thick. The case is an impressive piece of brushed stainless steel, with a domed mineral crystal. The dial is well made, although i have found two little particles of dust, but they will be easy to remove. Maybe i don't like very much the dimensions and font of the numbers, but it's just a detail.
The caseback is even more impressive. It is very well made, and i like a lot the drawing engraved on it. The watch came with a second transparent caseback, so i have made a little trick - i have slightly lubrified the rubber gasket, to allow me to change the caseback easily opening it only with my hands (without tools)! :-X
This is the watch with transparent back installed. The movement is the well-known Molnija 3603, with just a basic finish (blue hands, polished bridges). It's visually nice though (except the rough engravings in English on it), much more than an Unitas. However, the original caseback is too nice, so i will keep that one.
The view without caseback, unfortunately, is not very pleasant, because of the ugly plastic spacer and the empty holes intended to screw the old metal spacers O| It's a bad feature of many recent Poljots, but at least it has a theorical advantage of a better shock protection in comparison with a metal spacer. Anyway, it is covered by the caseback, so no problem.
The watch has also some other little defects. The screwdown crown, for example, is apparently a great piece, but at a closer view it was not perfectly designed (see the radial lines - one in the lower left corner is wrong O| ). It needed some drops of oil, the tolerance between stem and crown tube was very tight and did not allow a good feeling during the winding (now instead it's a real pleasure to wind the big pocket watch caliber ). The release spring is also quite powerful and you need a bit of care if you want to ensure a long life to the threads of the crown tube. Moreover, the lume is very weak, and different between numbers and hands. The strap has inscriptions in German, and it's very comfortable, definitely of good quality.
In conclusion, the Poljot Aeronavigator is anyway one of my favorite watches! Even with some little imperfections (some of them easily resolved with some easy operations), it is very well made for the price. Mine is running at a great -4 seconds per day. It's for sure one of the best options if you want an inexpensive oversized "flieger" in IWC-style, with a pocket watch movement that is not less good than an Unitas.
