Dial, case and exterior details
The stated exterior combines Matte Black Dial with Applied Luminous Arabic Numerals (3, 6, 9, 12) and Broad Arrow Hands; Anti-Clockwise Unidirectional Rotating Bezel with Blue Ceramic Insert and Liquidmetal™ Diving Scale; Solid 316L Stainless Steel Bracelet with Patented Foldover Clasp and Diver Extension. The case specification uses 316L Stainless Steel (Satin-Brushed and Polished Finish). Inspect color and finishing under neutral light, since reflections and image processing can make polished surfaces, dial texture and metal tone appear different.
DD8912: functions and checks
Dandong 8912 Automatic Movement (Co-Axial Architecture / No-Date Function) is the caliber stated for this sport-watch configuration. Check winding, time setting, the date where fitted and available timegrapher readings. Water resistance requires a separate pressure test.
Size and wrist fit
This is a larger-wearing configuration. Check thickness, lug span, crown or crown guards and the angle of the first links or strap before choosing it.
Who should consider this configuration?
This version fits buyers looking for a sport or dive-watch layout, but the design and any stated depth rating are not proof of water resistance. Arrange a separate pressure test before water exposure. The reference to match is 217.30.42.21.01.002.
Compare this model with other Seamaster configurations by reference, movement, size and exterior specification.
QC checklist for this reference
- Match the reference 217.30.42.21.01.002 and the complete dial, bezel, case and bracelet or strap configuration to the order.
- Use straight-on, neutral-light images to inspect printing, applied markers, hand alignment, date or day centering where fitted and visible exterior condition.
- Inspect bezel alignment and action, crown seating, lume consistency and date placement where fitted.
- Check winding, time setting, clasp or buckle operation and an available timegrapher reading for DD8912.
- Check link or strap condition, articulation, sizing range and the security of the clasp or buckle.
Practical questions before ordering
Is this an original Omega watch?
No. This is a VS Factory-made replica offered by an independent retailer. Brand and reference names identify the design and configuration being compared; they do not indicate authorization or manufacture by the original brand.
Will every production batch look identical?
No. Components and finishing can change between batches. Treat the current product specification and the QC photos or video supplied for the order as the final reference.
Does a stated depth rating confirm water resistance?
No. A separate pressure test is required before exposing any watch to water.
