Quartz movement with sweep second


LittleWatchShop

Recommended Posts

I just fixed a neighbors clock--replaced the quartz movement...two for 10 bucks on amazon...lol

Anyway.  Instead of the 1-second tick of the hand, it is continuous.

Anybody open one of these up to see what they are doing?  Cannot be too clever if they sell them so cheap.

I am guessing a stepper that is clocked about 10x normal.

Hi Repaired many of these Quartz modules using scrap units They come in many styles and types, round shaft  euroshaft etc. Continious sweep , step sweep ,quiet, and ticking also chiming.  The internals comprise of Circuit board  rotor stator and plastic wheels, on some of the older units the plastic de natures and crumbles away, battery terminals get salted up, duff batteries being left in.  I always try to repair before replacing. They are yet another inovation within the Horological world and are here to stay like quartz watches embrace the new technology. But never scrap a mechanical clock and fit a quartz that is just non on that is not clock repair that is a bodge.

Indeed...would never consider it!

I have only repaired one...and it was recently.  Classic battery acid problem.  Oddly did not destroy the main contacts, but inside the unit, contacts were corroded.  I cleaned then resurfaced with solder and that did the job.

Funny...prolly spent half an hour doing the repair on a $5 item.  It's the journey!

I have several clocks with these cheap sweep movements. But after a year or so, they start giving problems, like gaining or losing time, up to several minutes a day. I even had a couple that started to make a "chugging" sound like a toy train. I found that putting a drop of Moebius 9000 quartz oil on the pivots of the rotor solved this problem. But I'm not sure if it would damage the plastic eventually.

Anyone tried re-pivoting or rebushing a plastic quartz movement? ?

No never had to do that always had the spares but I repaired a cheap alarm clock, when the spring broke it broke a plastic peg off the pallet (pin pallet) all plastic. Drilled it out and used a sliver of bamboo glued in. Took longer than the clock was worth but it was a present and they thought a lot of it.  New probably cost a tenner. happy client.   some things are worth doing for people , no charge for the job as it was a bodge.

    • The Boro has changed quite a lot over the last 20 years, and not for the better. I actually moved out of the town 15 years ago to a small village not far away. Thanks for the pdf! Looks a great read. I'll get it printed today and put it on my work bench!
    • Not having all the fancy equipment, this is a way I came up with. I never said it was the best, the most ideal or the safest way. Working on balances is always a delicate task whereby full concentration & common sense should prevail. I was well aware of the "dangers" / short comings involved, hence my "warnings", as quoted above. The balance wheel of the Omega was nice true, flat and one could clearly see how much gap there was left before the grinding wheel would touch the balance wheel. I stopped when the generously applied diamond paste started to touch the rim of the balance wheel, which turned out to be with a seat thickness left of 0.1mm. Tapping the remainder of the staff out went easy and flawless. My idea of penning this article was to show/share a way which, in my case, perfectly succeeded. If deemed to risky, or if the balance wheel is not true or has a wobble, other methods have to be followed.
    • I loved his explanation of a teardown 😅 Ex military Richard Perrett, pretty knowledgeable guy.
    • I also see a bit of danger for the wheel, at least you have to keep away from it and may get a too thick rest ring. My rest rings are about 0.05 mm. Better way would be a grinding wheel touching the staff with its circumference. Frank
    • Not easy to find this one everywhere,  so it depends where you are located. Joining it back together might be possible, i have silver soldered mild steel before even with traditional plumbers lead and its a pretty strong joint, but bere in mind this is only 1mm diameter.  The join would need to be very accurate,  it not something i have heard of anyone trying before. The part no 401 is the swiss code number and relates to watch winding stems in general
