Testing Note
These readings were recorded from this individual watch during its pre-shipment QC inspection.
Mechanical movement performance can vary depending on mainspring power, watch position, ambient temperature and testing conditions. The recorded +14 seconds/day represents the movement’s performance at the time of this inspection and should not be interpreted as a permanently fixed daily rate.
For this individual watch, the rate should also be considered together with amplitude, beat error and functional testing rather than judged from a single measurement alone.
3235 Movement Performance
This Clean Factory Rolex Datejust 126234 is equipped with a 3235 automatic movement operating at 28,800 vibrations per hour.
During this QC inspection, the movement recorded a +14 seconds/day rate, 272° amplitude and 0.3 ms beat error.
The amplitude and beat-error readings were recorded under the same testing conditions as the daily rate.
In addition to the timegrapher test, automatic winding, manual winding, time setting and date adjustment should be individually operated before shipment to verify the movement’s actual functionality.
Because the measured rate is +14 seconds/day, it is especially useful to record this value transparently rather than presenting the watch as having a more accurate rate than was actually measured.
White Roman Numeral Dial Inspection
This particular 126234 configuration features a white dial with Roman numeral hour markers.
The white background makes alignment and printing details relatively easy to observe during close inspection. QC should therefore include the dial as a separate inspection area rather than focusing only on the movement.
Important details include:
* Roman numeral positioning
* Dial printing clarity
* Hour-marker alignment
* Hand alignment
* Date-window positioning
* Cyclops alignment
* Dial surface condition
Any obvious printing irregularity, contamination or alignment issue should be identified before shipment.
Case Dimensions and Weight
The individual watch inspected measured:
* 36.0 mm in diameter
* 11.8 mm in thickness
* 111.2 g in weight
The 36 mm case provides the traditional Datejust proportions, while the measured 11.8 mm thickness gives useful reference information for the actual watch inspected.
The 111.2 g weight is also an individual QC measurement. Bracelet sizing and manufacturing tolerances can cause small differences between watches, so it should not be treated as an exact weight for every 126234.
Sapphire Crystal and Date Display
The watch uses a sapphire crystal, which should be inspected for surface condition, clarity and correct installation.
Because the Datejust includes a magnified date display, additional attention should be given to the relationship between the date window and Cyclops lens.
QC should check:
* Sapphire crystal condition
* Cyclops positioning
* Date-window alignment
* Date numeral centering
* Date switching
* Crown date-adjustment operation
These details can be evaluated directly on the individual watch before shipment.
QC Observations
The Clean Factory Rolex Datejust 126234 combines a compact 36 mm case, white Roman numeral dial and 3235 automatic movement.
During this inspection, the movement recorded +14 seconds/day, 272° amplitude, 0.3 ms beat error and a beat rate of 28,800 BPH.
The watch measured 36.0 mm × 11.8 mm and weighed 111.2 g.
For this white Roman numeral configuration, dial printing and marker alignment deserve particular attention because the high-contrast dial makes small visual differences easier to identify.
The movement data, case measurements, weight and exterior details should all be considered together when evaluating the individual watch. A factory name alone does not replace an actual pre-shipment inspection.
