Is your Ocean Star
the real deal?
The Mido Ocean Star is a professional-grade dive watch offering a ceramic bezel, 200-meter water resistance, and the Caliber 80's 80-hour power reserve at an accessible price. Its strong value proposition and sporty design have made it a frequent target for counterfeiters.
How to authenticate a Ocean Star
Ceramic Bezel Insert
The Ocean Star features a unidirectional rotating bezel with a ceramic insert. The ceramic should have a rich, deep color (blue, black, or green) with precisely engraved and lume-filled markers. The 60-minute scale should be sharply defined. The bezel should rotate with distinct clicks. Counterfeits use painted aluminum bezels that scratch and fade.
Caliber 80 Movement
The Ocean Star uses the Caliber 80 automatic movement with 80 hours of power reserve. Through the exhibition case back, the movement should display proper finishing with a signed Mido rotor. The movement should keep time accurately. Counterfeits use generic movements with shorter power reserves.
Screw-Down Crown
The Ocean Star features a screw-down crown for water resistance rated to 200 meters. The crown should thread in smoothly and seat firmly against the case. It should feature the Mido logo. When unscrewed, it should have distinct positions for date and time setting. Counterfeits have push-pull crowns or poorly threading screw-downs.
SuperLuminova Application
The dial indices and hands are filled with generous amounts of SuperLuminova for underwater legibility. The lume should glow brightly and last for hours in darkness. Under normal light, the lume dots should be uniform in color and size. Counterfeits have dim, patchy lume that fades quickly.
Case and Bracelet Quality
The Ocean Star case is robustly constructed stainless steel with a mix of brushed and polished surfaces. The bracelet features solid links with a secure deployment clasp and diving extension. All surfaces should be well-finished. Counterfeits have lightweight cases and hollow bracelet links.
Helium Escape Valve
Some Ocean Star models include a helium escape valve on the case side for saturation diving. This valve should be precisely machined and functional. Its presence and correct positioning should match the specific reference. Counterfeits either omit this feature or add a non-functional decorative element.
Ocean Star counterfeit warning signs
Aluminum Instead of Ceramic Bezel
The genuine Ocean Star uses a ceramic bezel insert that is scratch-resistant. If the bezel shows scratches easily, the color fades, or it feels lighter than expected, it is an aluminum insert from a counterfeit.
Poor Water Resistance
The Ocean Star is rated to 200 meters. If the watch fogs up after hand washing or shows moisture inside, it lacks proper water resistance sealing and is counterfeit. Never test water resistance yourself — have a watchmaker check it.
Weak Lume
Genuine Ocean Star watches have bright, long-lasting SuperLuminova essential for dive use. If the lume barely glows or fades within minutes of darkness, the watch uses cheap luminous paint and is counterfeit.
Hollow Bracelet Links
The Ocean Star bracelet should feel solid and weighty. If the links feel hollow, rattle when shaken, or the bracelet feels disproportionately light, the bracelet is counterfeit.
