A fake Aquatimer Deep Time copies IWC's dive watch with a mechanical depth gauge. The case, dial and hands are the easy part for a replica factory. The depth gauge is not. Most fakes show a blue hand and a red hand that look right in photos, but only the pusher at 4 o'clock and the caseback tell you whether anything inside measures depth. That system is where I start.
One naming note. IWC calls these the Aquatimer Deep Two and Deep Three. "Deep Time" is collector shorthand, not a catalog reference. The Deep Two arrived in 2009 in steel. The Deep Three came back in 2022 in titanium. Replicas follow both.
Why the depth gauge decides the watch
On the real thing, water pressure pushes a diaphragm, and the movement turns that into two readings. A blue hand tracks current depth. A red hand stays at the deepest point reached until you reset it. That is a mechanical instrument, and it is the reason the watch exists.
Replica factories cannot build a pressure-sensing diaphragm at this price. What they do instead is fit a hand that moves when you press the 4 o'clock pusher, or a hand that does not move at all. I test it dry. Press the reset pusher and watch whether the red hand snaps back to zero with a clean click or drifts.
Tells that show on the wrist
- Depth pusher: on the Deep Three it sits flush and returns with spring tension. Fakes often feel mushy or sit proud of the case.
- Hand shape: the red max-depth hand has a specific arrow tip. Replicas tend to make it thicker.
- Inner bezel: the dive scale should line up at 12 with no gap and no misprint at the 15 and 45 marks.
- Dial print: the depth rating and the "AUTOMATIC" text should be crisp under a loupe, not fuzzy.
- Caseback: the Deep Two has an engraved depth-gauge diagram. Replicas often use a sticker or a shallow laser etch.
- Lume: hands and indices should glow the same color. A green hand next to blue indices is a giveaway.
Case, size and finish
The Deep Two is 46 mm in steel. The Deep Three is 46 mm in titanium. Both are large, and both sit tall because of the gauge. A good replica gets the case profile close, with a chamfer that catches light along the lugs and a crown guard that does not look cast. Titanium versions should feel light and look gray, not chrome. If a "titanium" Deep Three feels heavy and shines like steel, it is steel with a coating.
Movement reality
Most replicas run a generic automatic or a quartz in the cheaper tiers. The Deep Three replica often hides a 28,800 bph clone under a decorated rotor. You will not get IWC's 120-hour reserve, and you should not expect it. What you can check is the beat rate and the date change. A slow, sticky flip at midnight is normal on budget movements. A date that changes at 3 p.m. is not.
Price tiers
Entry fakes sit under a hundred dollars and show it: printed dial, weak lume, a depth hand that is glued in place. Mid tier runs a few hundred and gets the case shape, sapphire and a pusher that moves something. The top tier gets the dial and caseback right and uses a decent automatic, but the gauge is still cosmetic. Pay for finish and movement, not for a working instrument, because that part does not exist in replica form.
Before you pay
- Ask for a video of the pusher being pressed and released.
- Ask for a close-up of the dial at 12 and at 6.
- Confirm case material and thickness in writing.
- Compare the date window position against reference photos of the real watch.
- Ask whether the caseback is engraved or printed.
Bottom line
A fake Aquatimer Deep Time can look convincing on a desk. It cannot measure depth, and that is fine as long as you know it. Judge the replica as a dive-style watch: case shape, dial print, lume and movement. If the seller claims a working depth gauge, walk away. The real Deep Two and Deep Three are instruments. The replica is a tribute with a pusher.
