You thought you’d never see the day, but here it is. I’m servicing a Quartz watch 😉
I got myself a proper quartz watch tester, as you have to be able to measure the average consumption, something you can’t do with a run-of-the-mill multimeter.
Not that I am a great fan of Quartz watches, but Seiko at least builds proper movements, and not the throw-away plastic trash that others put in their watches…
This watch was sent in by Torsten from Hong Kong, and it stops from time to time, and needs a service. I measure a power consumption of 2.9 micro-amperes and that’s too much. Everything below 2.5 is fine, so there is too much dirt.
The wheel bridge actually has 2 jewels in it – that warms my heart a bit.
The gasket for the crown is almost completely dissolved – time to order a new one.
Bilingual day wheel.
For a quartz movement, this is as good a build quality as it gets.
Set and clutch lever assembly.
Bottom plate cleared.
On the top plate, I start by taking off the circuit board.
And here it is with its four screws.
This is a very sizeable motor coil indeed – no wonder the movement consumes over 2 micro-amperes.
With the gear bridge removed, you can see the wheels of the gear train.
Everything ready for the cleaning machine.
Reassembly starts off with the gear train.
I put the circuit back in, and test the movement. Power consumption is down to 2.1 micro-amperes, and I’m happy with that.
Now I can put the bottom plate back together.
The dial and hands go back on.
And I can case the movement.Back together and ticking.
