Real Omega Aqua Terra 150m Details
Buy tier 2. Tier 1 uses quartz or a low-grade automatic, a mineral crystal, and a stamped caseback. Tier 3 adds a decorated movement and a closer case profile. The gain over tier 2 is small for the price gap.
What the real watch is
The Omega Seamaster Aqua Terra 150M 41 mm runs calibre 8900. Power reserve is 60 hours. The 38 mm version runs calibre 8800 with 55 hours. Both carry METAS Master Chronometer certification, resist magnetic fields to 15,000 gauss, and hold rate at 0 to +5 seconds a day. Water resistance is 150 m. Retail for the steel 41 mm is about $6,600.
Head to head
- Case: The genuine measures 41.0 mm across and 13.2 mm thick. Tier 2 examples measure 41.0 mm to 41.5 mm and 13.0 mm to 13.8 mm.
- Movement: The genuine 8900 beats at 25,200 vph. Tier 2 uses a Seagull ST2130 or Miyota 9015 at 28,800 vph. Rotor engraving copies the Omega text. The gear train does not.
- Crystal: Tier 1 ships mineral glass. Tier 2 and tier 3 ship sapphire. Anti-reflective coating quality changes by batch.
- Dial: The teak pattern on replicas is stamped. The date window bevel is shallow.
- Bracelet: End links on tier 2 sit flush on some batches and leave a 0.3 mm gap on others.
- Water resistance: Ratings on replicas are claims. Gaskets are not pressure tested. Do not swim with one.
Checks before payment
- Ask for a lume shot and a crown close-up.
- Ask for a timegrapher photo. Rate inside +/- 10 seconds a day is acceptable for a clone movement.
- Confirm crystal material in writing.
- Confirm case diameter and thickness with calipers in a photo.
