Sometimes there are little metal washers like these underneath the crown wheel...is the watch winding and setting ok? J

You forgot there's one other feature that makes the 1900 interesting is the A and B display feature. One of the nice features of a paper tape machine is you can run long or infinite until you run out of paper timing plot liquid crystal displays can only go across the display typically. Some timing machines have a memory feature you can get one or two screens. The 1900 has another mode that lets you display twice as long of a display. Nice if you're looking for problems in the gear train binding issues. Then the amplitude thing does come up. I'm not even sure If it go down to the 100 before it gives you false numbers. I was visiting a friend with the 1000 machine he was very excited with how well his pocket watch was doing. He was looking at the amplitude on the timing machine I was looking at the balance wheel and visually look very bad. It's why I typically ask people how does the watch look or even in this discussion you need to physically put the watch close to in beat before you put it on the timing machine.

First, I'm a complete novice and I'm looking to start my tool collection for watch repair. I have my eye on the build your own watch tool kit that is listed on Esslinger website. I did a search on the forum but didn't find anyone talking about this kit. Has anyone used it and is it worth the price? https://www.esslinger.com/build-your-own-watch-tool-kit/

Nothing is as unsettling as completing an overhaul and discovering some little part reappearing out of (seemingly) nowhere. Now you've not only fully completed your first overhaul, but successfully figured out a problem....Outstanding! J

When you quench the steel, try to scratch some glass with it. If it doesn't scratch, then it's probably not high carbon steel.

that's called mystery metal, for use when its required that the steel rusts and sinks. Regular mild steel, ie 1018 does not have enough carbon to be heat treated. Remember all that talk about drill rod? Get some O1, heat to bright red (in sunlight) use an oil quench and then temper and you will be off to the races

My wife bought me this Official Cosmonauts for me for our wedding 15 years ago. It was my Grail watch before I knew the term. The stem broke awhile ago. Eventually I decided to take it to Right Time in Denver. Fortis finally shipped the parts after a couple months and got it back yesterday. Oh how I've missed it! I am really digging it on this new black nato with matching satin stainless steel hardware (originally got this strap for my Lunar Pilot).

Good call back-loader supporters! My Swiss army Victorinox knife wasnt thin enough but the ikea salad knife was look how clean the mvmt (dr25) is! I appreciate the group effort. Thanks
