I have used one very similar for a while now. OK for basic diagnostics and helps to eliminate the obvious (battery, free train, coil etc).  Instructions for use were not very good but it is simple enough to use.  There are better and more expensive ones for the professionals, but this type is ok for the rest of us.

Hi all, I am a new member and was looking for some advise. I have a fully kitted out workshop at work with the best equipment up to accreditation level from most brands but am looking to build a small workbench at home on a budget. The next thing on my list is a machine that will test the consumption of a Quartz movement. I have the all singing all dancing witchi one at work but was looking for a cheaper more basic alternative for at home. The cheapest I have found is the horotec Flashtest, has anyone any experience with this tester or is there a cheaper alternative. I only need to test the the consumption of the movement on 1.5v Watch's, I don't need it to do anything else.

Your help and advise would be greatly appreciated 

 

thanks

If you only need to test consumption (drain) all you have to is to get a broken quartz movement, remove all components, solder two wires to it to + and - pads, terminate these with a crocodile clip. you can now put a battery in it and measure with any common tester.

Otherwise there are cheap testers like this

Thanks for the reply, the tester you have linked to is not quite what I am wanting. I want to be able to remove the battery from say a tag Watch with a eta 955 112 movement and then put a prong on the + and a prong on the - which will then give a reading in μA. For example this eta calibre should read below 1.5μA for a new battery to last 2 years, if the reading is higher than this it means the watch needs a service because it's consuming too much from the battery and the battery won't last the 2 year period it should. The tests can be quite a low reading for some calibres so would think the devise used will have to have a digital display to be accurate. Some ladies Watch's should be .5 and the Rolex oyster Quartz can be as high as around 9μA going from memory so it needs to be quite accurate.

 

This is the cheapest version I have found so far that will do it. The test I want to do is test 6 in the instructions in the link below.

You are correct, I didn't realized that the device above doesn't do what you require. I could not find a cheap dedicated instrument so all you have to do is to use an external battery and a good multimeter. This one has a 20 uA setting which should work

Without knowing the exact name and type of the component, it's simply an electro-magnetic sensor. However in my opinion is that the watch runs it's pointless to see that it pulses - evidently it does. What you may want to know is the timing and shape of the pulse, for which you need a much, more sophisticated machine.

There is a benefit to such a detector as it is a quick way to determine whether a non-running watch is suffering an electrical/electronic fault or a mechanical blockage since a mechanically seized movement will still pulse without the hands moving.

A simple diagnostic routine for a non-running quartz watch might be;

Pulse detected - mechanics need freeing/servicing

No pulse - check continuity of coil

If coil is open circuit then replace coil

If coil is good but there is still no pulse then electronic module is faulty

 

At this level of simplicity a tester can be picked up off eBay for as little as £15 or so and could save a lot of time if you do a lot of quartz movements. Something more sophisticated would certainly be of benefit if you going to get into repairing the electronic modules but then the cost does go up considerably.

I was reading up about this tester and nobody has passed any coments about the `Horotec Flashtest` tester, that is why I have mentioned it; specifically. Maybe someone who hasn`t seen my prevoius article will see this one.

I have one and used it for the BHI Quartz servicing exam. A great little device that does almost everything you need at the fraction of the price of a Witschi 

Can't compare this to Witschi, which has a full screen oscilloscope showing the shape of the pulse (important on the latest generation, low drawn movt.s), memory, and heaven known how many things more. A top laboratory would get that, an hobbyist or a budget professional the $30 boxes mentioned in the thread above.

I think unless you're working on quartz a lot, it's hard to justify the cost. Please don't do this with your Omega's but if you have a cheap quartz movement and suspect the train is stuck. You can use a cheap Chinese demagetiser $15. Place the movement and press the button. The hands will spin and the second hand is likely to spin off into orbit. See pics. No damage was done to the movement and it still keeps time. And no the rotor was not demagetised. No I'm not accepting liability for this BAD practice. Note how fast the second hand is rotating!

The Witschi is a serious machine with a serious price which is not suitable or justifiable for the hobbyist, the horotec tests voltage consumption, lowest working voltage, coil resistance, battery voltage under load and end of life indicator and the rate. Which is all I'll ever need.

(Test battery consumption). My point is that you can have all that for maybe $80, not $439. But to each one his own.

    • Ladies and gents, I found the most awesome old gold watch chain!  It has spring links!  I am always so careful with my antique pocket watches, and still fear to drop them, even while on a chain. I've re-staffed a number of balance wheels that no doubt suffered a similar fate. But this chain has lessened that fear somewhat.  So my "watch of today" was my beautiful Elgin 339 clipped to this chain.
    • For me, there’s no binary yes/no answer to this. It really is a matter of feel, experience, inspection under magnification, the age of the movement and what a replacement costs vs invested effort to “revive” it that all play a role determining the answer above. For an Omega 56x series reverser wheel you’ll spend more time trying to revive a reverser (which, by the way is also much more serviceable, but also harder and more expensive to find a replacement for) than you would an a Sellita SW200 where replacements are cheap and easy to find.
    • That's what I did after my Pearl machine stopped working. I've run about 5 watches through it so far and get results as expected. One interesting note is that their customer service says the machine comes with a 2 year warranty but that is not indicated on the website and when asked via email they are unable to provide a copy of the warranty, which I believe runs counter to US federal law 🤷‍♂️  Luckily for me the service center they use for repairs is local to me so if I ever do need to have it serviced I won't have to ship it in its HUGE box.
    • @JohnR725I live in a “3rd world” country (South Africa) and even here you can’t make a middle class living charging $120 to service a watch. I make many times that spending that same amount of time in my day job. But quote the average someone $200 to service their inherited vintage Omega (that stopped working 20 years ago) and you’re told you’re effing mad. This is why watchmaking is dead as a profession in modern times; everyone wants that cool mechanical watch, no one considers what it costs to maintain it. A wrist watch is no longer an essential tool, it’s novelty jewellery. So I do it as a hobby, a make a few videos and I fix broken things. If this hobby can make a little money to at least contribute to its vast expenses then that’s a bonus. I have many other hobbies that are just money pits, so there’s at least that. Speaking of making videos: there’s a lot of criticism being levelled at YouTube watchmakers, either because they don’t show enough detail, or that they talk too much, or that they’re hacks, or whatever other negative thing you can imagine. But these YouTube watchmakers have done more to expose watchmaking to the average Joe than what any of the professional watchmaking institutions have ever done. Professional watchmakers scoff at these “hacks” in their comment sections but fail to see how these YouTubers create interest in the average Joe and turn them into enthusiasts. Anyway, enough rambling from me…
    • This Suizo 1950s AS1361N 10 micron gold plated Automatic got an outing today. It is a gents watch, but is quite a diminutive piece (as was typical for the time). It is also very well engineered. The plating has a few wear marks, but other than that it is looking pretty good for its age. There is one minor discrepancy though. The dial states 25 jewels but the rotor says 21 jewels. Oh well, I guess nobody's perfect. It got a new crystal as the old one had resisted my best polishing efforts, but still wasn't up to scratch. I also treated it to a period correct 17mm dark green leather band from a job lot of 1950s or 1960s straps I picket up recently.  Before you ask, no, I am not responsible for all of those scratches on the rotor, they were there long before I got my hands on it. Suizo is almost certainly a Achille Hirsch brand.
