QF Factory Rolex Day-Date 228238-0061 Counterweight Edition — QC Test & Measurements
QF Factory Rolex Day-Date 228238-0061 Counterweight Edition — QC Test & Measurements
Product Overview
This QC report documents an individual QF Factory Rolex Day-Date 228238-0061 Counterweight Edition, featuring a yellow gold-tone case and bracelet, green Roman numeral dial, sapphire crystal and 2836 automatic movement.
QF Factory offers multiple configurations of the Day-Date 228238, including versions with different movement specifications and weight arrangements. Therefore, identifying the exact configuration is an important part of evaluating this model.
The inspected sample recorded a 186.4 g weight, a 40.0 mm case width and a 13.1 mm thickness.
These measurements, together with the Timegrapher results, provide a reference for distinguishing this particular configuration from other QF Day-Date versions.

Sample Reference: These measurements apply to the individual watch inspected. They should not be treated as fixed specifications for every QF Factory 228238 configuration.
What We Found During This QC
1. 2836 Movement Recorded 0 Seconds/Day
The 2836 automatic movement was tested using a Timegrapher.
The recorded results were:
0 sec/day · 280° amplitude · 0.1 ms beat error · 28,800 BPH
The daily rate of 0 seconds represents the observed result during this particular testing session. It does not mean the watch will maintain zero deviation under every wearing condition.
The 280° amplitude and 0.1 ms beat error provide additional information about the movement’s condition during testing.
These readings fall within the movement-performance reference used for this pre-shipment QC evaluation.
Actual performance may vary with power reserve, testing position, temperature and wearing conditions.
2. Counterweight Configuration: Actual Weight 186.4g
The inspected watch recorded a weight of 186.4 g.
This measurement is particularly important because QF Factory offers several Day-Date configurations with different weight characteristics.
The term Counterweight Edition refers to a weight-adjusted configuration intended to provide a heavier overall feel than certain standard versions.
However, a higher weight does not automatically establish better movement performance, exterior accuracy or manufacturing quality.
The 186.4 g measurement identifies this particular inspected configuration.
It should not be interpreted as the weight of every QF Factory 228238 or as proof of a specific internal weighting material or construction method.
3. Actual Case Measurements
Measurement Actual QC Result
Case Width 40.0 mm
Case Thickness 13.1 mm
Weight 186.4 g
The case measured 40.0 mm in width, consistent with the nominal 40 mm Day-Date size designation.
The recorded thickness was 13.1 mm.
These figures provide useful reference data when comparing different QF Factory versions, particularly where movement configurations or case construction may vary.
Measurements may differ slightly depending on the exact caliper contact points and individual production tolerances.
Important Version Identification: QF Factory 228238
One of the most important considerations for this reference is that QF Factory offers multiple Day-Date versions.
Buyers should not assume that two watches with the same factory name and reference number necessarily have identical movement configurations or weights.
For this inspected watch, the confirmed QC specifications are:
Identification Item This QC Sample
Factory QF Factory
Reference 228238-0061
Version Counterweight
Movement 2836 Automatic
Measured Weight 186.4 g
Thickness 13.1 mm
When comparing another QF Day-Date 228238, the movement type and actual weight should be verified before treating it as the same version.
A product listing that states only “QF Factory Day-Date 228238” may not provide enough information to identify the exact configuration.
This distinction is particularly relevant when comparing standard-weight, counterweight and other movement options offered in the market.
Green Roman Numeral Dial Inspection
The green dial with Roman numeral hour markers is a prominent visual feature of the 228238-0061.
The contrast between the green surface, gold-tone markers and hands makes printing and alignment important inspection areas.
The relevant visual checks include:
* Green dial surface consistency
* Roman numeral positioning
* Hour-marker alignment
* Hand alignment
* Day-window positioning
* Date-window centering
* Printing clarity
* Dial cleanliness
The day and date displays should be evaluated separately because both are prominent elements of the Day-Date design.
Close-up photographs are useful for identifying printing inconsistencies, visible dust or alignment differences that may not be apparent in standard product photographs.
Day and Date Function Inspection
Unlike a simple three-hand watch, the Day-Date includes both a day-of-week display and a date display.
For the 2836-based configuration, the inspection should cover crown operation, time setting, calendar adjustment and the correct operation of both displays.
Particular attention should be given to the positioning of the day text and date numerals inside their respective windows.
The calendar mechanism should be operated according to the movement’s adjustment requirements. Forcing the crown or attempting calendar correction during the movement’s engagement period can increase the risk of mechanical damage.
Yellow Gold-Tone Case and Bracelet
The inspected watch features a yellow gold-tone case and bracelet.
For this type of finish, the relevant QC areas include:
* Surface color consistency
* Polished case surfaces
* Case-edge finishing
* Bezel alignment
* Crown operation
* Bracelet-link articulation
* End-link fit
* Clasp engagement
* Visible scratches or coating irregularities
The exterior color should be examined under neutral lighting because warm or strongly colored lighting can change the apparent shade of the finish.
The description yellow gold-tone refers to the visual finish and does not establish solid-gold construction or a particular precious-metal composition.
Sapphire Crystal and Cyclops
The supplied specification identifies a sapphire crystal.
The crystal inspection focuses on surface condition, clarity, installation and visible defects.
Because the Day-Date includes a date magnifier, Cyclops positioning and date-window alignment are also important visual inspection points.
The magnifier should be assessed from a straight-on viewing position and from additional angles to distinguish actual misalignment from perspective effects.
QC Assessment
The inspected QF Factory Day-Date 228238-0061 recorded:
0 sec/day · 280° amplitude · 0.1 ms beat error · 28,800 BPH
Its physical measurements were:
40.0 mm width · 13.1 mm thickness · 186.4 g weight
The recorded movement data falls within the pre-shipment QC reference range.
However, the most important finding for this model is the need to identify its exact version.
Because QF Factory offers multiple configurations, the movement type and actual weight should be confirmed individually rather than relying only on the factory name, reference number or Counterweight Edition label.
This particular report documents the 2836 automatic movement and 186.4 g counterweight configuration.
These details make the report useful as a comparison reference for future QF Day-Date 228238 inspections.
QC Status
Movement Data Assessment: Within QC Reference Range
Physical Measurements: Recorded
Version Identification: 2836 Automatic / 186.4 g Counterweight Configuration
Final Shipment Status: Subject to completion of functional and exterior inspection.
The recorded Timegrapher and measurement data alone do not establish that every exterior and calendar-function inspection item has passed.
FAQ
