Needs the PC to be calibrated against a known accurate quartz watch - has a facility to do that. Shows: running SPD, amplitude (need to set the lift angle) beat error, and unlike the cheaper timegrapher machines, also a visual of the movement waveform - like an escapement analyser.
Tg 0.5.0 available as a free download for Windows (maybe other OS too, not sure)Īdd a clip-on guitar pickup microphone (remove the foam pad) very very cheap from ebay or similar. When you are happy, clean the o-ring groove, and put a very small amount of silicone grease on the o-ring and reinstall the back.ĭo not be obsessive - do this once and don't keep opening and readjusting. Be careful - you could cause expensive repairs quite easily.Ĭheck the timekeeping in several positions and adjust accordingly. If it has a free sprung balance with microstella screws you are in a different level of skill but if you want to proceed buy an inexpensive tool to do so on eBay.
If the watch doesn't have a free sprung balance but rather a screw or levers to adjust timekeeping, again consult youtube on how to proceed. Buy one of the cheap sets of Rolex back removal tools. If you want to proceed, buy a cheap Chinese Timegrapher and watch a youtube video on its use. Second, do not open a watch under warranty. However, processing this data would require more time as the watch reading would need to be interpreted from a picture.First, I would not worry about getting a Timegrapher etc.unless you are handy at dealing with delicate items and are willing to regulate the timekeeping yourself. Another method might be to use a high-speed camera that takes a picture of the watch next to some time standard. This operation would be difficult to perform without a specialized program. Therefore, each data point contains two pieces of information from that instant: standard time and your watch’s time. The user plugs in some time in the near future and presses the button when their watch reaches that time. Pressing this button also simultaneously records a predetermined hh:mm:ss. The time source it synchronizes with is quite good.Īlthough a spreadsheet is capable of doing the same math, this app is worth the money (in my opinion) because of a specific feature: a button that will instantly record atomic time when pressed. Instead, I would call this app a (very user-friendly) specialized calculator. This app omits questionable features such as ‘magnetism detection’ or calculations made from audio recordings of your watch. I recently heard in a watch channel, about another app, so it’s time to delete this one and give the other one a try. So after more than a month, I have no clue as to how my watches are running. Then I do another timing run, and I get a zig zag line, flunctuating by double or triple the amount of the first.
I do a timing on a watch for days or even longer, and get a nearly straight line for that run. Original review: I’ve been trying out this for a month or so and either all of my watches are extremely erratic, or this app doesn’t work. It has a lot of nice features that the others I’ve used done, like the comments. Now I let the app decide the minute and make the measurement but the second hand and that works. I think the problems I had earlier somehow had to do with what happens when the minute hand moves past the minute marker but the seconds are not there yet. I ended up to I sticking with this app and I’m glad I did.
