I was looking at your hunter. Did you try your luck with Omega ?
I hope you will not find my message disappointing, neither pure reality, but i believe there's something wrong with your watch.
The case serial number and hallmarks are for a watch manufactured in the vicinity of 1917-1920.
The 84 / .875 hallmarks stand for Russian Empire silver quality; while the rampant bear hallmark stands for Swiss silver manufacture.
Now, the 1917, was the last year of Russian Empire, as it fall after the 1917 Russian Revolution, which led... briefly, to Soviet Union. Though, the hallmarks remained through 1930's, so it's not the best year indicator, but the movement serial does not give me piece of mind.
Is simply a huge gap between the case and movement serials. At first the difference was in the vicinity of 100.000, and it is known that Omega / Louis Brandt / LB & Frere, made ebauches for others. So let's say that in those early years, if the movement would have been in the 1.5 mill. range, the case, should be in the 1.6 mill range.
Another indicator could be the name at 6 position, above the sub seconds dial. My guess is that is the import name for the Russian market, and most likely is a Swiss name too; and it might ease the work in finding out the year of manufacture or retail.
The problem remains the year. The movement looks cca.1890's. The case says 1910's - 1920's.
In 1894 they've developed their 19" cal., which would remain a standard for the movements they will sell after that year. So i see no point Omega / Louis Brandt would use other movements, unless of course in stock.
My guess so far: It is either an early 1890's with a wrong case but with a correct movement cover, or it's a fake.
