Many of the old timer watchmakers may still be using antiquated stuff that is probably nowhere near as good as these.

They can't be calibrated - most seem to have a calibration port, but no way to do it that I have found.Īgainst all of that, they are a tiny fraction of the price you would pay for a fully featured professional model. They don't have gain controls, so occasionally you get a watch that they can't read properly. They won't time quartz watches - well, actually you can fiddle with them to get some sort of readings, but nothing very useful. They will time co-axial movements, but won't give you proper amplitude readings for them. They only give timings to the nearest second per/24 hours.

If you're brave enough to touch up the regulation on your own watches, then they are really an essential tool. If you're an amateur who just wants to check how your watches are running - and especially check how the watch is running after that expensive service you just paid for :thinking: - then they are fine. 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.I have one of these - I think they are sold under various names, but probably these cheapest ones are basically all the same.ĭecent instrument ? A professional watch maker, would probably want one that has many more features than this provides to do thorough problem diagnosis quickly or get through a lot of watches. 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.
