I agree :))

Yeah, actually it amazes me how many quartz watches have this, and you don't really realize unless you have a bigger collection of vintage ones. at this point I have at least 5 in my collection that lag behind with 3 corrected with their trimmer cap and two that need oscillator replacement.

that sounds like a lot, at least they're not all beeping every hour

Thank you

Hi, there are better videos on youtube for this, my knowledge is limited.

@@VintageDigitalWatches When I say a bit more in-depth I mean where you would put the probes on the board and on what setting to make sure you get the reading. Regards

I don't usually check them when I do overhauls for items that go in my collection because I will see their drift as they sit on display. But if I were doing this for a different person I would do some sort of check, in 3 days if you sync it with your phone you should see a drift that would cause problems. For an electronic watch I wouldn't be happy to see a 2 minute drift a month and have to set it every now and then.

Have been looking at Electronika but haven't got one yet.

Will try iy, but with this small scope will probably not capture it.

They nailed the design.

I made sure to get one with as low as possible capacitance not to interfere with the capacitance of the trimmer cap

​@@VintageDigitalWatches If we speak aboul CL (load capacitance) which is usually shown on the label -- it depends on the watch design, at least in common case. May be this watch was designed for CL=0, but most common for me is 12.5pF.

yes it absolutely could. if its a quartz analog it could be a bad crystal, low battery or it just needs to be serviced.

@@mrcoolr429 Yeah, above list from Seth is spot on. I have seen an analog quartz that the hands were catching on each other when they intersected each hour which caused a delay. Is the watch you speak about a digital or an analog?

Most quartz testers sense the electro-magnetic impulse in the stepper motor, ie they only work with analogue displays. Some testers can be used on LED/LCD, I believe they have an ultrasonic sensor but not sure what they pickup. I don’t believe any new testers have this capability nowadays.

@@precertvideo "I find your lack of faith in the quartz testers disturbing" In fact I have two which are perfectly capable of testing everything that the human race has put in the watch market, from LCD/LED to Mechanical including the Bulova Accutrons. Their most important component is a Temperature Stabilized Oscillator (TCXO) which is

@@oturgator I have total faith in quartz watch testers!

@@oturgator what kind of testers do you have?

@@karlisok8996 I have the Seiko Quartz Tester QT-99 and the Vibrograph M80

didn't plan on doing it, but doesn't sound like a bad plan.

@@VintageDigitalWatches you have unique content and very good quality I noticed that if you post more frequently like follow-up on different watches and projects would definitely benefit you. That's the only issue I see here. Otherwise best videos I've seen on the subject. I've seen all of your videos. Big fan 👌

This is the only tools I have that comes close to reading frequency, I agree there are better tools out there but this one did the job and the watch is keeping excellent time.

Ebay, catawiki, but they rarely come up for sale.

@@VintageDigitalWatches I try draw it, if you have Instagram I can show

Can you send me original size of this watch, I going print it on 3d printer, because is only way get it incredible design

@@PabloEscobar-xe4xi No, it is impossible, the watch has many round shapes that can't be easily measured. Here is one for sale: www.ebay.com/itm/265573649046?hash=item3dd56c4a96:g:bJ0AAOSwJOBiHl~X

Da da :)

I can help you understand, imagine if you have a rolex or GP mechanical that doesn't keep time, would you not service it? Quartz replacements are common repair practices on quartz watcges that drift.

@@VintageDigitalWatches isn't it obvious what the problem is? You replaced the crystal with a newer more modern crystal. You managed only a very slight improvement but still not able to get 32768 oscillations per second. Don't you find that odd? The problem is not the crystal. The problem is that other components on the circuit board are begining to fail. Crystals don't fail. They don't wear out like a car engine! They simply occillate. You've butchered a watch for no good reason!

Watch the video till the end.

@@VintageDigitalWatches I watched it to the end and you proved that despite a new quartz crystal, it still runs slow, and your point? You can't eyeball an accurate watch against another watch and declare it's roughly accurate. You need to prove that the new crystal occilates at 32768 oscillations per second.

Consider this. NSK is one of the world's largest manufacturers of occilating crystals. To meet specification they have to provide an ageing rate for their crystals depending on application. The figure is a theoretical figure and the worst case scenario is +-3 ppm per year!!and that is for an industrial grade crystal. That is the same as .0003% of 32768 per year. The odds of you noticing that time shift are virtually nill! The single biggest cause of poor time on a quartz watch are related to the motherboard, contamination poor connections and low voltage. People assume that just because they have replaced the crystal and notice an improvement that that must have been the cause. it isn't.
