Quartz movement with sweep second

[LittleWatchShop]

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.

Peering through the tinted case, looks like the same stator as the older tic-tics but the rotor is flying, so must be many poles on it.

Or maybe just pulsing it faster!

I have a Seiko like that. These are nice, aren't they. But stll looked down by clock lovers

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!

BTW, I have a wall of clocks of various sizes that was also part of my inheritance.  Maybe 30 or so.  They are in the queue for repair (actually some are working now).  All will be treated with the respect they deserve!!

It Is not the fact that you spent a half hour doing it its the fact you fixed it, the satisfaction.

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.
