UFO Factory Rolex Daytona 126500 Free-Sprung Version Pre-Shipment QC Review

The UFO Factory Rolex Daytona 126500 is available in several configurations, including regulated, free-sprung and weighted versions. This pre-shipment QC inspection covers the free-sprung version equipped with a Cal.4131 automatic chronograph movement.

The inspection records the actual movement performance, dimensions, weight and sapphire crystal configuration of this specific watch.

During the timegrapher test, the movement recorded a daily rate of +10 seconds per day, an amplitude of 290°, a beat error of 0.0ms, and a beat frequency of 28,800 BPH.

Because multiple UFO Factory 126500 versions are available, buyers should confirm the exact movement and weight configuration before ordering rather than relying only on the factory and model name.

Free-Sprung Cal.4131 Movement Performance

This specific UFO Factory Daytona 126500 is equipped with a free-sprung Cal.4131 automatic movement.

During testing, the movement recorded a daily rate of +10 seconds per day, an amplitude of 290°, a beat error of 0.0ms, and a beat frequency of 28,800 BPH.

The 290° amplitude indicates a strong power state during the test, while the 0.0ms beat error was particularly well controlled.

Based on this specific timegrapher reading, the movement was operating steadily at the time of QC. Actual daily accuracy may vary according to power reserve, wearing habits, temperature and resting position.

Free-Sprung, Regulated and Weighted Versions

One of the most important points when purchasing the UFO Factory Rolex Daytona 126500 is that several versions are available.

The main configurations currently include:

* Free-Sprung Version
* Regulated Version
* Weighted Version

The watch tested in this QC review is the free-sprung version.

These configurations should not automatically be treated as the same product. Differences in movement structure, weight and pricing may exist, so buyers should confirm the exact version before ordering.

If the free-sprung configuration is specifically required, it should be clearly stated when placing the order.

40mm Case and 12.3mm Thickness

This specific watch measured 40mm in width and 12.3mm in thickness.

The 40mm case maintains the familiar Daytona proportions, while the 12.3mm measured thickness provides useful real-world data when comparing UFO Factory with other Daytona 126500 versions.

Actual measurements are particularly useful for version comparison because advertised specifications do not always reflect the dimensions of every individual production batch.

142.4g Measured Weight

The total measured weight of this specific free-sprung version is 142.4g.

Weight is especially important for the UFO Factory Daytona 126500 because a separate weighted configuration is also available.

For this reason, the 142.4g figure should be treated as the measured result of this particular free-sprung watch rather than a universal specification for every UFO Factory 126500.

Buyers specifically looking for the weighted version should confirm the actual version and weight before ordering.

Sapphire Crystal and Exterior QC

The watch is fitted with a sapphire crystal, providing good optical clarity and practical resistance to everyday scratches.

Exterior QC should also include the dial, chronograph subdials, hour markers, hands, bezel, case finishing, pushers, bracelet and clasp.

When several versions of the same model are available, these physical details should be considered together with movement configuration, dimensions and weight.

Overall QC Assessment

Based on this pre-shipment QC inspection, the UFO Factory Rolex Daytona 126500 free-sprung version delivered stable movement readings and balanced physical specifications.

The Cal.4131 movement recorded +10 seconds per day, a 290° amplitude, 0.0ms beat error, and 28,800 BPH. The watch measured 40mm in width, 12.3mm in thickness, and 142.4g in weight.

The most important point for buyers is version identification. UFO Factory offers regulated, free-sprung and weighted configurations, so the factory name and model number alone are not enough to identify the exact watch.

For accurate comparison, buyers should confirm the movement configuration, version type, actual weight and QC measurements before ordering.
