  1. Hello again. I was checking the performance of my Strela chronograph (Poljot 3133) and found an interesting anomaly. By looking at the timing graph, I would say that aside from the watch needing some adjustment, one of the two swings seem to be inconsistent. Am I right in stating that? I was pretty confident that I will find some obvious problem with the impulse pin, pallet jewel, or escapement. But taking these parts out of the movement and reviewing them under the microscope did not reveal any obvious problem. Nothing seems loose, damaged or bent. I then cleaned the parts and put them back in the movement and as expected got the same anomaly on the graph. I am very much in the mood to disassemble, clean and oil the whole mechanism but before I go there, I thought it may be a good idea to check with the forum on what is likely causing this behavior. I am attaching some photographs of the parts but they were made with my phone pointed through the eyepiece of the microscope and may not contain enough details. Guess I should also say that this is the first time I will be fully disassembling a chronograph. Cheers!
  2. Hi everyone. My interest in horology started over a decade ago and my fist exposure to the watch repair began with attending TimeZone online courses (Level 1 and 2). In order to complete these courses, I had to purchase some minimum tool set. From that time, I have been continuously adding tools to my workshop and slowly improving my knowledge. Then at some point in the last couple of years I have also discovered Marks channel and, as most of you, developed high admiration for his skills and experience. I consider myself a beginner but over the time I did get my hands dirty working on certain number of affordable movements ranging from vintage to newer Japanese, Russian, and entry Swiss movements. Mainly I service my own collection (mostly three hands, affordable watches) but sometimes, I also get to repair my friends and collogues watches. In most of the cases I was able to complete the work successfully. I don’t recall causing a major damage (selective memory, lol) but there were, for sure, some close calls. To wrap up, thank you for reading my introduction. I am looking forward to further learn and share on this forum.
