A fake Atmos 568 is a replica of the Jaeger-LeCoultre Atmos clock, the torsion-pendulum table clock that winds itself from small changes in room temperature. Replicas copy the glass case, the brass frame, and the dial layout, but they do not copy the gas capsule and bellows that make an Atmos run. A genuine Atmos 568 sells for several thousand dollars; a fake costs a fraction of that and behaves like a quartz clock or a decoration.
What Makes the Atmos 568 Different From Other Clocks?
The Atmos has no battery and no winding key in normal use. A sealed capsule at the back expands and contracts as the air around it warms and cools, and that motion keeps the mainspring wound. The torsion pendulum turns once a minute, so the movement uses very little power and can run for years without help.
Reference 568 is one of the modern Atmos cases: a rectangular glass box in a brass frame, with a plain dial and thin hands. Genuine examples sit in the thousands of dollars. That price gap is what the replica trade feeds on.
What Does a Fake Atmos 568 Cost?
Prices scatter across a wide band. Sellers list fakes from under $100 to a few hundred dollars, and the number often says more about the listing than about the clock.
- Under $100: a glass and brass ornament. The "movement" is a quartz unit or an empty shell.
- $150 to $400: better case work and dial printing closer to the original, still a quartz or simple mechanical movement.
- Above $400: rare, and the seller is charging for packaging and story more than for the clock inside.
For comparison, a genuine Atmos starts in the thousands and climbs with limited editions. No fake at any price has a gas capsule that winds a mainspring.
How Can You Tell a Fake Atmos 568 From a Genuine One?
Start at the back of the clock. Every genuine Atmos has a sealed capsule and a bellows assembly there, and most fakes have something else in its place.
The Capsule and Bellows
Look through the rear glass. A genuine unit shows a metal drum with a stack of bellows, linked to the mainspring by a thin chain or lever. A fake shows a battery slot, a quartz module, or a plain plate. No capsule means no Atmos movement, whatever the listing claims.
The Transport Lock
Genuine Atmos clocks ship with the pendulum locked, using a lever or screw that holds the balance still until the clock is level and settled. Fakes skip this part because there is no torsion pendulum to protect.
The Glass Panels and Frame
Genuine panels are thick, with polished edges and a snug fit in the frame. Replica glass is thin, edges feel rough, and the brass frame shows solder lines or uneven plating at the corners. Run a finger along the inside of the frame and compare the four corners.
The Dial and Printing
Zoom in on the logo and the hour markers. Genuine printing has crisp edges and even spacing. Replica printing looks soft, and the font weight drifts between the logo and the numerals.
Serial, Papers, and Service Records
A genuine 568 carries a serial number on the case that matches its paperwork. Ask about service history too. Atmos clocks need attention every couple of decades, and owners tend to keep the receipts.
Does a Fake Atmos 568 Keep Time?
Some do, more or less. Most fakes hide a quartz movement in the base, so they keep quartz time until the battery dies. They do not run for years on temperature changes, and whatever pendulum is fitted will not survive a move without damage.
A fake with a decorative pendulum often stops within days. Treat any claim of "runs without power" as a warning unless the seller can show the capsule.
What Should You Check Before You Buy?
- Ask for a clear photo of the back with the case open.
- Ask whether the clock runs, and for how long it has run since the last service.
- Confirm the case measurements match reference 568 and check the glass thickness.
- Ask whether the transport lock is present and working.
- Pay with a method that allows a return if the clock arrives dead.
Is a Fake Atmos 568 Worth Buying?
As a decoration, maybe. As a clock, no. You pay for a look and you get a look. Buyers who want the real torsion movement should save for a genuine Atmos or hunt a restored vintage one with papers.
Frequently Asked Questions
Can a watchmaker service a fake Atmos 568?
Most will not. There is no parts supply and no gas capsule to refill. The quartz unit inside a fake can be swapped, but that is a battery change, not a service.
Do replica Atmos clocks wind themselves from temperature changes?
No. Replica makers do not copy the gas capsule. It needs precision welding and a controlled gas fill, and those parts are not sold on the open market.
How do I spot a fake Atmos 568 in listing photos?
Look at the back panel, the case corners, and the dial printing. Blurry shots of the movement side, a price far below market, and a seller who dodges questions about the capsule are the signals that matter.
Why is the Atmos 568 copied at all?
The shape is simple to fake. A glass box with a brass frame and a round dial can be built in a small workshop, so the outside is easy and the inside is the hard part.
