movement comparison between 21,600bph and 28,800 bph

[jdh91741]

The Omega on the left may be a replica

[icecue7]

@jdh91741 Both actually (probably) are. Left has a Chinese movement (based on Miyota), and while the right has a Swiss movement, the PO uses Caliber 2500, and has 25,200 bph.

[jdh91741]

@icecue7 The one on the left is a 'ringer'. How can you determine the one on the right is also a replica? My reason for asking is: I plan on purchasing a pre owned Omega and I am looking for fraud indicators.

[icecue7]

@jdh91741 I only said it because of what the uploader said. The PO uses Omega 2500 Movement/Caliber 2500. While it is derived from the Swiss ETA movement 2892, the bph is not 28,800. The one in the video probably uses a ETA 2824 which is a common workhouse movement and it has 28,800 bph.

As for other fraud indicators, I can't help much. I just know tidbits here and there from my time on watch forums, haha.

Yeh man I'm more interested in the outgassings and farts than anything else!

[dukiemac]

And then what happened?

[367419]

would love to know where you got the rep omega from. looks great

[jradetzky]

whoa, the one on the right goes so smoothly, like flying

[riceoobxg]

to be a little fair, the dial on the left is bigger it seems. this magnifies the choppiness of the DG making it even worse.

0:25 and 0:34 -- Fart!!!!!!!!!

We use the cheap ones for our IED!

GO TIMEX!

They're both replicas.  The real Omega Planet Ocean ticks at 25,200 beats per hour (7 per second).

I'm just beginning at the bottom of a what looks like a mountain of research needed to purchase my first decent watch. I'm liking the smoothness of the movements in technology such as Seiko's Spring Drive.

[lolcat23]

@acidbombquick there is nothing smoother then the spring drive, because it never actually stops. where as swiss lever escapement stops 28.800 times an hour. If the smoothness of the seconds hand is the only criteria. then go for it. spring drive!

[vfrmaverick]

@lolcat23 Actually when video'ed under slow motion it does have small stops. The smoothest would be the rolex quartz prototypes that had dozens of beats per second.

[lolcat23]

@vfrmaverick I would like for you to show me a link of that. Last i heard, the spring drive never fully stops, its always completely fluid.

Dozens of beats per second is ridiculously low hertz, a normal quarts runs at 32000 hertz, which is helluva lot smoother than "dozens of beats per second"

[vfrmaverick]

@lolcat23 Remember the crystal has oscilations that are detected by a computer, after 32000 it sends power to move the seconds hand. It is not a mechanical concept like a normal balance wheel. Do a search for rolex 5100 here on youtube and see it for yourself.

[lolcat23]

@vfrmaverick yes, but you are missing the point of the spring drive. there is never a complete stop in the motion of the train, there is only a little less brake or a little more break to either catch up or slow down. there is never a complete stop! not like a stepmotor quartz watch. Methinks you are not talking about the same thing as me. Im talking about the Seiko Spring drive. Check it out.

[waarismijnkat]

Are both real? Or is one a replica?
