The top-line statistic when describing a mechanical watch movement is the bph/vph. Every time I've asked an eBay seller about the timing of the movement, and they say "runs great, probably under a few minutes a day", its a huge red flag that they don't have knowledge about what they are selling, undermining their credibility and in turn, my interest in buying from them.īeats per Hour (BPH) or Vibrations per Hour (VPH) If you notice one of your watches struggling or having problems, you can generate some decent ideas as to what is wrong in a few minutes so you can decide where to take it.Ĭonversely when selling a watch, including the Beats Per Hour (BPH) statistics on your 'For Sale' post shows you to be a more knowledgeable seller who understands what serious buyers want to know. If you like to buy pre-owned, especially vintage watches, its a fast way to get a snapshot of the movement you are dealing with so you know if you need to bring it in for service right away (or return it). There are a few major benefits to having a Timegrapher. You don't even have to take the back off the watch. Although not the heavy duty analytics tools real watch repair shops use, for under $200 it is a very worthwhile tool to have around, and its incredibly quick and easy to use. A timing machine, or timegrapher, lets him get a quick snapshot of how a watch is running.īeing someone who likes to really set up shop in my hobbies, and having already started the TZ Watchmaking course, I thought a Timegrapher would be a great addition to my watchmaking desk and a useful tool to determine how well my watches are running.

I don't think the newer computer bearing watches could be anything near as accurate were they not able to set themselves from the network.Why You Should Own A Timegrapher (and how to use it)Įvery time I bring a new watch to my watchmaker, he immediately puts it on a stand and shows me as a little blue screen drawing lines, mumbles something, and then gives me an idea of the movement's health. My gut impression however is that its unusually accurate for a 'sport' type watch. Then I could get a more exact measure of how off it is. One thing that I have been meaning to do is attempt to sniff the frequency either via inductance or sound. (mostly on my wrist) or off (sitting in a drawer) It is waterproof too so if I want to, I can shower, swim, etc. The inaccuracy remains pretty much the same whether its warm. It also appears to be temperature compensated. But, to its credit, even though its at least 20 yrs old now, the Suunto is still an accurate timepiece. The barometer is useful for the weather aspect.

Around the house, what's the point of wearing a bulky watch? The highest 'mountains' around here measure maybe 500 meters. But these days I almost never wear it because I almost never get to go hiking. My current watch (a an old Suunto Vector) does much better than most watches, it gains maybe one or two seconds a month. Curled wire for mechanical isolation I suppose. Seems to be a piezo element, fixed to the metal thing that sticks out of the microphone assembly.

Modern design compared to other watch analyzers I have seen. The display is colour LCD, 480x272 pixels. A closer look at the microphone assembly. The red wire is ground, black is +8V Yellow is signal. Notice the threaded metal inserts for the screws, also for the PCB screws. If anyone knows anything about this, please let us know Inside the unit, slightly more interesting. The USB calibration port is for factory use. This watch runs 18.2 seconds per day fast Unexciting back of the unit. It can be rotated in two axes for testing the watch in different positions. Even the firmware seems good Anyway, here it is: The watch is clamped to the microphone assembly. Quite impressed with the design and build quality on this thing. It does this by listening to the sound of the movement and then interpreting the signal. It is for analyzing the performance of mechanical watches.
