The shape of the case reminds the Sturmanskie series, the blue internal bezel is in the same style. The silver dial is differently "brushed" in two zones (upper part is brushed vertically, lower part orizzontally).
On the caseback, the symbol of the presentation as gift for the 25 years of the work in Polish mining industry. Original Poljot bracelet. The movement is the Poljot 2626 23 jewels, needed a bit of work but now works well.
