Default ETA Quartz weird pulse...ETA 950.001

Anyone know what might be compatible with this movement that's more current and cheaper?

But morw to the point of the thread, this one I have is pulsing at I reckon around 100BPM, but doesn't want to tick for long.. .well it's a 2 hander.

I don't want to strip it and clean it as imo it would seem as though the circuit is faulty, but I'm not sure if the circuit has some weird difference... if anything I thought it should be either 60bpm or something like 2 as all it needs to do is shift the minute hand....


Any ideas please would be most useful!

Right it seems as though 956.032 or 956.042 or even 956.102 or an HR775 would be a fit....depending on hand height, movement height and 2 hands or 3 hands...

But I'm still intrigued by the pulse rate....

Could something be contacting a T-spot on the circuit, if it has one? Check for a too-long screw in the wrong place from the dial side, or something bridging traces on the circuit board itself. Microscope recommended, front and back of the circuit board.

Different hand hole size, but those are the closest you’ll be able to find.

I believe the 950 is quite a bit thicker as well.

Interestingly all of the two hand quartz movements that I have checked, Seiko Casio, Citizen and ETA, are designed to, and pulse only, once every five seconds, or 12btm, unlike the movements with a second hand which pulse at the expected 60bpm.......... Oh the joy of owning a vintage QT-99 quartz tester, thank you very much John (Tiger UK)

That's what I was expecting on my Flashtest John.

Thanks Noah and Steph. I'll tackle it and see what I find....I would expect it has a fault however I think a clean and then proper test and will see what's what...
Steph the minute is the difference right at 1.7 as opposed to 1.6 on the 001? If so I can likely open the minute hand up slightly.

Hmm I'll keep looking for a 4000 circuit for the 001 and see what happens in the mean time.

Yep. The eta 95x.xyz series uses 0.70/1.20 hand sizing. The 950.001 uses 0.60/1.20

Most 2 hand movement pulses at 5-10secs. Mainly because there’s no second hand to see, so there’s no point in pulsing every second. It’s probably to save battery? A seiko 5y30 pulses every second though, even though it’s only got 2 hands.
