Testing Note
These readings were recorded from this individual watch during its pre-shipment QC inspection.
Mechanical movement readings can vary according to power reserve, watch position, temperature and testing conditions. The recorded +7 seconds/day represents the performance observed at the time of testing and should not be interpreted as a permanently fixed daily rate.
For QC evaluation, the daily rate should be considered together with amplitude, beat error and actual functional operation.
V4 Integrated 8800 Movement
The main point of interest in this V4 configuration is the integrated 8800 automatic movement.
The movement recorded:
* Daily Rate: +7 Seconds/Day
* Amplitude: 291°
* Beat Error: 0.0 ms
* Beat Rate: 28,800 BPH
Under the recorded testing conditions, the movement showed stable performance.
The integrated movement configuration is also an important distinction when comparing different VS Factory versions of this reference.
V4 Version and Two Movement Options
For the current VS Factory Seamaster Diver 300M configuration, two movement versions are available:
1. 2824-based version
2. V4 integrated 8800 movement version
The V4 inspected in this report uses the integrated 8800 movement.
This distinction should be clearly confirmed before purchase because the two versions should not be treated as the same movement configuration simply because the exterior model is identical.
For customers comparing the versions, the movement architecture is therefore one of the most important technical differences to understand.
The integrated 8800 configuration provides a movement structure that is more closely associated with the intended 8800-style architecture, while the 2824-based configuration follows a different mechanical platform.
This does not mean that movement appearance alone determines overall watch quality. Reliability, winding operation, time setting, date switching and actual timegrapher performance should still be checked on each individual watch.
42mm Case, 13.6mm Thickness and 196.1g Weight
The individual V4 watch inspected measured:
* Case Diameter: 42.0 mm
* Case Thickness: 13.6 mm
* Measured Weight: 196.1 g
The full-steel construction gives this Seamaster a substantial physical presence.
At 196.1 g, the watch has a noticeably solid feel in the hand and on the wrist. The measured 13.6 mm thickness is also relevant when evaluating how the 42 mm case sits on the wrist.
These measurements are based on the actual QC sample rather than nominal specifications.
White Dial Inspection
The white dial is one of the defining visual characteristics of reference 210.30.42.20.04.001.
Because of the strong contrast between the white dial, dark bezel and applied elements, alignment and surface cleanliness are especially noticeable.
QC should focus on:
* White dial surface
* Dial pattern consistency
* Printing quality
* Applied hour-marker alignment
* Hand alignment
* Date-window positioning
* Date numeral centering
* Dial cleanliness
The dial should also be viewed from several angles and under different lighting conditions to identify any obvious alignment or surface issues.
Sapphire Crystal and Exterior Inspection
This V4 configuration uses a sapphire crystal.
During pre-shipment QC, the crystal should be inspected for:
* Surface condition
* Clarity
* Correct installation
* Edge condition
* Visible scratches or damage
* Clean dial visibility
Exterior inspection should additionally cover the bezel, case, crown, helium escape valve, bracelet and clasp.
Bezel and Diver 300M Details
The rotating bezel is an important functional and visual component of the Seamaster Diver 300M.
QC should check:
* Bezel rotation
* Bezel alignment
* 12 o’clock marker positioning
* Rotation resistance
* Excessive play
* Bezel surface condition
The crown and helium escape valve should also be visually inspected for alignment and external condition.
These components contribute significantly to the characteristic appearance of the Seamaster Diver 300M.
Full-Steel Bracelet and Wearing Feel
This reference uses a full-steel bracelet, contributing substantially to the 196.1 g measured total weight.
Pre-shipment bracelet inspection should include:
* Link articulation
* Surface brushing and polishing
* Link alignment
* Bracelet-to-case integration
* Clasp opening and closing
* Clasp locking security
The bracelet should articulate smoothly without obvious sticking while the clasp should close and lock securely.
QC Observations
This VS Factory Omega Seamaster Diver 300M 210.30.42.20.04.001 V4 recorded:
* +7 seconds/day
* 291° amplitude
* 0.0 ms beat error
* 28,800 BPH
* 42.0 mm measured diameter
* 13.6 mm measured thickness
* 196.1 g measured weight
The integrated 8800 automatic movement showed stable performance under the recorded testing conditions.
An important feature of the current VS configuration is the availability of two different movement versions: a 2824-based version and the V4 integrated 8800 version inspected here.
For this reason, the exact movement configuration should be confirmed when comparing different VS versions rather than relying only on the model reference or exterior appearance.
The V4 integrated-movement configuration is particularly relevant for buyers who place greater importance on movement architecture in addition to exterior finishing.
Combined with the 42 mm case, sapphire crystal, full-steel bracelet and white-dial configuration, the inspected V4 provides a well-balanced overall package and is one of the versions worth comparing for this Seamaster reference.
Individual QC remains important because movement readings, dial alignment, bezel operation and exterior assembly can vary between individual watches.
