DD3235: functions and checks
Custom DD3235 Automatic Movement (listed 72-hour power reserve) is the movement stated for this configuration. Ask QC to demonstrate every displayed function, crown position and available timing reading on the actual watch.
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. The oyster option also affects balance, flexibility and sizing.
Who should consider this configuration?
Choose this configuration for the exact reference, exterior treatment and displayed functions. Compare the complete specification because collection names and nicknames do not identify every option. The reference to match is 126603.
Compare this model with other Sea Dweller configurations by reference, movement, size and exterior specification.
QC checklist for this reference
- Match the reference 126603 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 every displayed function and crown position on the actual watch.
- Check winding, time setting, clasp or buckle operation and an available timegrapher reading for DD3235.
- Check link or strap condition, articulation, sizing range and the security of the clasp or buckle.
Practical questions before ordering
Is this an original Rolex 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.
