The Short Answer
Buy the titanium-case copy of the Aquatimer Deep Three. It comes from the same factories that build the better Submariner replicas, and it is the closest thing to the genuine watch in case shape, weight, and crystal quality. What it lacks is a real depth gauge. Every copy at a sane price has a decorative gauge hand, or a hand driven by a pusher instead of water pressure. Treat the gauge as decoration, not instrumentation, and the rest of the watch holds up well for daily wear.
What the Genuine Aquatimer Deep Three Is
- Titanium case at about 46 mm across, with a tall mid-case
- A mechanical depth gauge that reads current depth and stores maximum depth on a second hand
- An IWC automatic movement with about two days of power reserve
- Domed sapphire crystal with inner anti-reflective coating
- An internal dive scale set by a crown on the case flank
- Water resistance rated for genuine dive use, not splash protection
Where the Copies Diverge
- Gauge function: the real one senses water pressure, the copy does not
- Thickness: most copies sit 1 to 2 mm taller because of the movement spacer
- Case finish: replica titanium brushing is coarser and the lug edges are softer
- Lume: weaker and it fades faster after dark
- Water resistance: often untested, and caseback gaskets can arrive dry
- Crystal: sapphire on top-tier copies, mineral glass on cheap ones
- Movement: a Seagull ST2130 or a clone ETA 2824, 28,800 vph, about 38 hours of reserve
The Pick: Deep Three Titanium Copy
This is the version to chase. Case proportions match the genuine watch within a fraction of a millimeter at the bezel, the titanium has the correct dull gray tone instead of the shiny gray you see on steel copies, and the sapphire crystal sits at the right height above the bezel. Look for a seller who can show a timegrapher photo with the beat rate set between 0 and +10 seconds per day, and who states the caseback gasket was greased before shipping. Budget for a pressure test by a local watchmaker before you swim with it.
Runner-Up Options
Option 2: Deep Two Stainless Copy
Steel instead of titanium, so it feels heavier and the color reads brighter. Case lines are easier to machine, which means the fit and finish are often cleaner than the titanium copy. The trade-off is weight and a less convincing wrist presence next to the real thing.

Option 3: Aquatimer 2000 Style Copy
No depth gauge at all, so there is nothing to fake. The dial layout is simpler and the internal bezel mechanism is the main draw. Fewer moving parts means fewer failure points and lower prices.
Option 4: Skip It and Buy a Diver Copy Instead
If you want a water-ready replica, a Submariner-style copy with a tested screw-down crown and a pressure test holds up better. The Aquatimer shape is more interesting, but the Submariner platform has more parts support and easier servicing.
How to Vet One Before You Pay
- Ask for a short video showing the gauge hand and the crown action, shot in one take.
- Request caliper photos of case thickness at the lugs and at the crown guard.
- Confirm the crystal material in writing, since mineral glass scratches within weeks.
- Ask for a timegrapher photo that shows rate, amplitude, and beat error.
- Confirm whether the caseback gasket was greased and whether the watch was wet tested.
- Take the watch to a local watchmaker and have it pressure tested to 3 bar.
- Budget for a basic service: cleaning, gasket replacement, and regulation.
- Check that the bracelet end links sit flush against the case and that spare links are available.
- Confirm the lug width before you order a strap, since copies drift from the 22 mm genuine spec.
Cost and Value
- Entry copies under $120: mineral glass, rough brushing, no pressure testing
- Mid-tier copies $150 to $260: sapphire, decent lume, clone 2824 inside
- Top-tier copies $280 to $400: titanium case, best dial printing, real AR coating
- Genuine Aquatimer Deep Three: four figures and up, and the only version that gauges depth
Practical Notes
Counterfeit watches cannot be imported into the United States legally, and customs can seize a shipment. The Swiss Made label is regulated, so no replica qualifies for it. A copy with a cosmetic depth gauge should never go on a dive, because the gauge tells you nothing about your depth and the case seals are unproven. Wear it on land, have it tested, and keep the real dive computer on your wrist.
