Same as the title
I wonder how far quart technology has come,
Can they invent an quart that have a smooth movement of the second that if you do not open the case back you can not tell if it is quartz of automatic (Obviously NOT State on the Dial) !

Several Seiko chronographs have a sweeping seconds hand, like this Sportura I own:

The hand that sweeps in these models is the chronograph seconds hand (the big, central one). The small seconds hand doesn't sweep and behaves in the same way as regular quartz seconds hands.

Grand Seiko Spring Drive is a hybrid between quartz and an automatic. I believe it technically is a free spinning barrel so there is no "beats" per say. There's no stop and start (or ticks). However, the starting price tag for SD is higher than any typical quartz.

The smooth second hand is in some quartz models, like the Precisionist. But if what you're looking for isn't a smooth hand, but a quartz that is indistinguishable from a mechanical, I don't think that exists. You can identify a mechanical by the stuttering second hand, usually between 5 and 10 beats per second (more typically 6-8). I can't think of a quartz that ticks more than once per second, but not completely smoothly.

So you need to look at bph - beats per hour.
6 beats per second is 21600 bph - pretty typical for automatic watch.
1 beat per second - is quartz. But if you manage to find, quartz watch with higher rate - you cannot determine if it's quartz or mechanical anymore.

Why not just buy an inexpensive automatic?

Many many threads on this very topic here on WUS. Please search. Yes the most affordable with a smooth sweeping seconds hand is Precisionist. Another would be an electronic tuning fork watch like the vintage Omega Constellation f300hz.

I'm not sure where you are located. If in the U.S. then a Macy's department store will have many of the Precisionist models to see in person.

Re: Quartz with smooth second hand movement?

Bulova Accutron is the only brand I am aware of that has a smooth quartz second hand.

Re: Quartz with smooth second hand movement?

I owned a Bulova Lunar Pilot which was a UHF Quartz. It had a smooth hand. It was a great watch but wasn't getting any wrist time so I traded it a couple weeks ago.
