I hereby inform the dear audience that since January 1st, I have newly established a watch repair workshop, where I perform all repairs in very short terms, at very affordable prices, and also have various new wall clocks for sale. Optical and physical works as well as jewelery works and all kinds of jewelery are made 25% cheaper than in larger jewelery workshops in Płock.
