Does a Seamaster 300M 212 moon phase replica exist?
Only as a replica. Omega never released a Seamaster 300M with the 212 reference and a moon phase complication. The 212 prefix belongs to the Seamaster Diver 300M family from the mid-2000s, a 300-meter dive watch with a date window, wave-pattern dial, and helium escape valve.

Moon phase complications sit elsewhere in the Omega catalog, mainly on Speedmaster and De Ville models. Any listing that pairs a 212 Seamaster case with a moon phase is a hybrid build, not a copy of a real reference.

Recognizing that gap is the fastest way to judge what you are actually being offered.

What the 212 reference really is
The 212.30 series ran on 41 mm stainless steel cases with a unidirectional dive bezel, screw-down crown, and a caseback engraved with the Seahorse medallion. Dial options covered black, blue, and white, all with applied markers and generous lume.
Omega Seamaster 300M 212 Replica Watch: Best Features Unveiled
- Water resistance rating: 300 m on the genuine watch
- Movement: Co-Axial automatic chronometer, certified by COSC
- Signature details: helium escape valve at 10 o'clock, wave dial texture
- Typical case size: 41 mm diameter, about 13 mm thick
None of those references ever carried a moon phase aperture. That is the core inconsistency in the listing title.
Why the moon phase on these builds is usually not what it claims
A true moon phase tracks a 29.5-day lunar cycle, so the disc advances a small fraction each day. Many budget replicas instead hide a 24-hour day and night disk behind the aperture. That disk completes a full turn every day and shows a sun and moon, not a lunar calendar.
The difference is easy to spot over a week. A real moon phase shifts position slowly. A day and night disk is back where it started within 24 hours.
How to check a moon phase function in person
- Note the moon position, wait 24 hours, and compare. Slow drift means a genuine lunar mechanism.
- Look for a recessed corrector pusher or a crown position that advances the moon disc alone.
- Check the aperture edges for rough cutting or printed foil rather than a layered disc.
- Confirm the date flips cleanly at midnight and does not drag the moon disc with it.
What else to inspect on a 212-style replica
- Bezel action: 120 clicks, aligned triangle at 12, no back play
- Crown guards and case finishing: sharp edges and mismatched brushing are common tells
- Dial printing: the Seamaster text should be crisp and level under magnification
- Lume: charge it for 30 seconds and check that all markers glow evenly
- Water resistance: treat any claim of 300 m as unverified unless a pressure test is documented
Do not swim or dive with a replica diver. Gaskets and case tolerances on unauthorized builds rarely match the rating printed on the back.
Legal and ownership reality in the United States
Replica watches infringe registered trademarks. Importing, selling, or trafficking them can lead to seizure by US Customs and Border Protection and to federal counterfeiting charges.
Buyers face fewer consequences than sellers, but seized parcels are not returned and refunds are rarely recoverable. Resale value is effectively zero, and servicing is difficult because parts do not interchange with genuine components.
Frequently asked questions
Is a 212 Seamaster 300M with a moon phase a real Omega model?
No. Omega built 212-reference Seamaster 300M divers with date functions only. A moon phase in that case is a third-party or replica invention.
Where does Omega actually put moon phase complications?
Mainly on Speedmaster Moonphase models and De Ville lines, plus modern Co-Axial Master Chronometer moon phase references.
Can a replica moon phase be repaired?
Sometimes, if the base movement is a common clone. Moon phase modules are the weakest link, and replacement parts are often unavailable.
Why do sellers list models that do not exist?
Combining a popular case with an exotic complication makes a listing stand out. The result is a fantasy model with no authentic counterpart to compare against.
What is the safest way to verify authenticity?
Have the watch inspected by an Omega-authorized service center and compare the reference number against Omega's own catalog before any money changes hands.
