MK ladies chrono doesn't tick

[Nickpan]

picked a battered one up for a tenner 'needs battery', but new battery leaves the chrono working, but not the time....

Hands turn freely with the winder, date turns over, but watch will not tick - I'm not clever enough to go down to component level, is it a faulty movement?  I could possibly change the movement if need be.

Could you remove the caseback and see what movement is inside?

All the JS25 movements I can find on Cousins have (0) jewels. Could it be a special custom movement for MK?

Are you sure it's 10 Jewels? Can you post a photo.

Does the second hand show any signs of twitching?

This is the time you need a Quartz Tester to see if you're getting any output.

[Nickpan]

ha ha!  I get todays Sillybilly award, it says 'no jewels'

no, hour - minute - seconds, all dead

Normally I'd add a drop of IPA with an oiler on the rear pivots, then give it a blip on the magnetic field generator, followed by a drop of fresh quartz oil.

[HectorLooi]

If there is no pulse, adding oil won't do any good. The time and chrono have separate circuits, so even if the chrono works, the time circuit might be bad.

Just get a new movement and replace it. They don't cost a lot.

Original OPs reply said the seconds hand twitched and then ran with a tap.

Also the question becomes is the watch worth the price of a new movement and what
experience and tools have they got for swapping the chronograph hands in particular.

[HectorLooi]

Hmm... one of us must be reading the wrong post.

OP didn't say second hand twitched or ran with a tap. He said he could change the movement if need be.

I got my 2 threads mixed up - I have a Diesel and an MK, both battered, both look like they need a new movement.  The Diesel twitches, the MK is 100% motionless, cannot be coaxed.  I edited this thread to remove the twitching reference, my apologies.

Neither are probably worth the effort, but it's nice to have a (new) hobby   

Some humans on the rest of the internet had a chrono working, with dead time hands, they tried a better brand of battery (probably a fresher one, not near expiry), and got their tick back.  I hope I've typed this on the 'MKors chrono works' thread   

[HectorLooi]

I wouldn't count on a "better" battery to be the solution. If the "better" has a higher current output to overcome a high current drain situation, it probably won't last very long.

I usually test the current drain of the movement before replacing the battery. If the current drain is high, I'll inform the owner that I could change a new battery but the battery life would not be very long. And if the quiescent current is high, the circuit board needs to be checked for leakage. But if the price of a new movement is this cheap, I'll just change a new movement. 

My advice is to get a new movement and change it. If only for the practice.

If you're going to be sticking with this then I suggest you get a cheap quartz tester to give you a better idea of what the movement is doing.

Not sure what batteries you use but it's always best to use a quality one and where possible the W High Drain version.

Thanks for the tip! What kind of "magnetic field generator" do you use? Is there a specific or suitable one for quartz watches?

I use the one on this type of tester.

The cheap 4 in 1 quartz watch testers incorporate a moving magnetic field , maybe just a spinning magnet  that might impose itself on the movement's rotor? It can free up a sticky movement . I cant say I like the idea of pushing delicate wheels and pivots through gummed up friction. I would think only a temporary measure. I changed the movement on one that I paid a quid for, that and a new glass came to 12 quid. Was an easy fix and the chrono hands came off with no problems.

Hence the drop of IPA to start with, sometimes if the owner just wants it running then you do what's needed.

The JS25 are running at about £15 + Delivery and when you
can get something like the below boxed with a strap for £20.

Haha. Haven't we all spent $1000 on a jewelling set just to replace a broken jewel on a $20 Russian watch?

Money is never an issue when it comes to satisfying our deepest desires! 

Although I'm not sure I understand your objection @AndyGSi. A new MK quartz chrono is about $200 to $250!? Sure, you can get something "like" it, but not with the MK logo, and as we all know, brand and looks are everything, never mind how it's running.

The photo I posted is a Ladies MK Chrono Boxed I recently purchased for just over £20.00

And here's what looks like a silver version of the OPs on eBay at the moment c/w strap.

Your $200 to $250 prices listed maybe new but looking at second hand prices
what they're asking bears no resemblance to what they're actually worth.

OK, I guess I thought you were comparing a new movement with a new watch. But you are right, if the owner has no sentimental feelings for the watch, a used one would financially be a good option.

[Nickpan]

although the £8.99 MK hasn't had any bids yet, sold price will likely be higher

[AndyGSi]

So 2 are new and I think the £65.00 even with the box and instructions is the exception to the rule.

Have you at least got the strap for it.

[HectorLooi]

Is it possible that MKs are made in China?

I hate fashion watches. They charge a lot for a $30 plastic movement.
