The case specification uses 316L Stainless Steel with 18K Rose Gold Plating. Inspect color and finishing under neutral light, since reflections and image processing can make polished surfaces, dial texture and metal tone appear different.
DD8500: functions and checks
Dandong 8500 Automatic Movement (Date Configuration) is listed for this time-and-date configuration. Review crown positions, hand setting, date centering, calendar changeover and a timegrapher reading taken under a stated test condition.
Size and wrist fit
The listed diameter sits in a broadly versatile range, but thickness and lug-to-lug behavior can make two watches with the same width wear differently.

QC checklist for this reference
- Match the reference 123.20.38.21.03.001 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.
- Demonstrate date adjustment and changeover; inspect dial-marker symmetry and bezel finishing.
- Check winding, time setting, clasp or buckle operation and an available timegrapher reading for DD8500.
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.
