Re: K2 Thread
There are different level of leaks as well as different levels of damage. Some battery leaks are so corrosive that once dried up, the negative springy contact breaks along with the corrosion of the leaked fluid. Hence unable to do easy cleanup, to get the watch work again.

I had a ISA movement powered Man U Chrono once, battery leaked and dried causing the negative contact too corroded beyond repair. Master God also give up...

not like this leh.



battery acid leaks, into circuit board, shorts live and negative, instantly killing components and the movement. thats all.



its like dropping ur HP into water, but in this case the "water" came from the battery.



watchmakers can clean up dried acid on battery contact points, and instantly movement comes alive, simply bcos the acid did not seep much or into any components inside the circuit board.the dried acid has become a insulator between battery and battery contact point, if you do not clean up, voltage or rather the electricity from the battery does not go inside the circuit to make the movement work.



its like some electronic stuff come with paper stuck in between the battery contact point to "stop" it from working untill end user decides to remove this insulator to let it start working again.



corrosion come very much after the above mention stuff. thus making ppl think corrosion kills the movement, which is not the initial cause that kills it leh.



in short change the battery asap when it stops.



in some case of expensive quartz watch like omega, just do a 1-2 yearly change even though watch is still ticking. some watch may still be ticking away, but acid has started to leaked already until it has leaked enuff to short some components.

How come when I brought my Seiko sportura there for battery replacement, found old battery leak and he said he can't do anything? Now the top pusher when depressed no reaction.




[quote="ronnie"]My first time to K2 was last Sunday after reading about Mr Goh on the web, and I bought a Monster from him. Hearing that Mr Goh was very good in fixing watches, I brought a "dead" Timex Watch to him. I was told by another watch store that my Timex watch was irreparable due to battery leak. I was quite sad as I remembered I paid quite a lot of money for the Timex watch. Was pleasantly surprised and impressed when Mr Goh managed to bring the watch to life! And he only charged me $10 to bring it to life.

see my post, not all leaks kill the movement instantly.



in ur case main time still ticking while chrono cant work??



if this is the case, only ur chrono circuit was affected by the leak, main time is still okie lo....

Re: K2 Thread
So to say , battery quartz movement is prone to these type of malfunction cause by battery leaks , auto much more reliable and not so risky compared to quartz , consider when one invest thousands of dollars on a watch.

Thanks man , Good to know info on quartz movement issue like these

in any case, its not plastic throughout



the green line are wires or rather metal tracks that lay out flat to connect components up.



the black pimple in ur pic is the ic, or generally known as a semiconductor package. in most watch module, a timer package



watch movement is a eletro-mech device that connected up via a pcb

http://en.wikipedia.org/wiki/Printed_circuit_board"http://sound.westhost.com/clocks/tb-f2.jpg" alt="" loading="lazy">



simple quartz clock pcb layout







a seiko 7a28 partial pcb















mechanical parts inside a quartz movement









looking at the pics, how can it be plastic throughout.



wat was shown after back cover aka screw back cover is open is just the surface of many layers of the typical watch movement.





i goggled using :

watch movement printed circuit board



quartz watch movement explained







In theory, it works like this:



1 Battery provides current to microchip circuit

2 Microchip circuit makes quartz crystal (precisely cut and shaped like a tuning fork) oscillate (vibrate) 32768 times per second.

3 Microchip circuit detects the crystal's oscillations and turns them into regular electric pulses, one per second.

4 Electric pulses drive miniature electric stepping motor. This converts electrical energy into mechanical power.

5 Electric stepping motor turns gears.

6 Gears sweep hands around the clockface to keep time.





In reality. this is what the inside of a quartz watch looks like.







1 Battery.

2 Electric stepping motor.

3 Microchip.

4 Circuit connects microchip to other components.

5 Quartz crystal oscillator.

6 Crown screw for setting time.

7 Gears turn hour, minute, and second hands at different speeds.

8 Tiny central shaft holds hands in place.

nothing is perfect to begin with.



auto can be svc over and over again, so long parts can be found, and no major shock suffered. initial cost of cos is higher when buying the watch



but the accuracy of general auto against general quartz is its downside.



quartz is much like a fuss free thing , take and go, how often can or do u need to change a battery?? once a year??



but a auto if stopped need to manually adjust before wearing again....



of cos being a watch forum, we all like a auto for watever reason we prefer

Re: K2 Thread
Nice info put up on quartz phantom.



Said right, there will be folks who beg to differ about quartz being unreliable or inferior to mechanical.



I remember a fellow member swore off mechanical movements after parts cannot be found and repair costs went too high.



It's your choice eventually.

Dun scare me leh? U mean quartz watch battery even when still got juice also might leak? I think the battery in my Hammie is around 4 years liao and the one in my SMP is around 2 years but both still ticking away..

Re: K2 Thread
OT a bit. Personally I have not had a battery leak on my watch, but I had a leak on a remote controller. Bought a replacement, and instead of throwing the old one away, I figured no harm put it under alkaline water to wash off the acid leak and let it dry for a few days. Surprisingly, it sprung back to life. Tried this last option instead of throwing your quartz watch, perhaps it might work?

i did this on several remote b4 from tv to aircon n fan, aircon remote hardest to pry open, not screw on, but snap on type of plastic



remote control pcb is relatively simple, u see a ic and many round spots only, thats it



remove plastic cover, took out pcb, wipe or spray with electronic contact cleaner.



put back and install fresh or useable battery.



use any phone or camera with camera lens on, put lens facing the "led" looking thing and press all the buttons, if it blinks the remote is working.



sometimes u get some buttons not working also, while some working. or totally not working lo.. depends on luck.



again depends on how much the leak has seep onto the pcb, has the acid started to "attack" pr breakdown the pcb 1st insulated layer yet.

I think Goh was extremly busy on Sunday. Passed by and saw him sold one TUDOR, one SEIKO titanium Diver and one SEIKO wall clock, all very nice ones. Pop and change out one crystal. Replace maybe 6 batteries & 3 straps. All within 30-40 minutes!



But he was unable to help me with my CASIO MTG, anyone know where to find a MTG 120 steel bracelet?

Re: K2 Thread
I think doing fine adjustment to improve accuracy of watch is tedious, time consuming and cannot charge you much without servicing the watch. So, most watchmakers will not do it for you from what I have experienced so far.
phantom150
Re: K2 Thread
To us its just abt in terms of seconds.



On the watch timing machine. There's more information.



In k2 machine, the 2 lines readback have to be consistent. It may be out by say only 5s, but if the 2 lines run haywire on its own. Regulating will only help for short periods of time. In such cases watchmaker will ask u to svc so the readback of the lines will be consistent. Which in terms will be able to regulate.



Last but not least, k2 is regulating with dial up position. Then he will run on winder and check timing after sometime for watches he serviced .



So why would he take such a job of regulating watchs n checking over few days?? So how much he shld charge? ?



No names, but someone actually felt he was charged 5 bucks for regulating the watch ex. The job was done in ard 10 mins. But u need to have a watch timing machine, proper case opener, n well trained hands to do it in this timing.
