QF Factory Day-Date 128235-0075 36mm QC Test

QF Factory Rolex Day-Date 128235-0075 36mm – Weighted 2836 Movement QC Review

The QF Factory Rolex Day-Date 128235-0075 is a 36mm weighted model featuring a rose-gold-style case and bracelet, brown dial with Roman numeral hour markers, sapphire crystal and a 2836 automatic movement.

This watch belongs to QF Factory’s more basic movement configurations within its Day-Date range. One of the main differences between the available versions is the use of a 2836 movement rather than a 3255-style movement.

Our inspection focused on movement performance, physical measurements, calendar operation and the decorative precious-metal hallmarks found inside the case and clasp.

2. 2836 Movement and Configuration Differences

This version uses a 2836 automatic movement, positioning it as a more basic movement configuration within QF Factory’s Day-Date range.

The principal distinction from a 3255-style version is the movement platform. Different movement configurations should be assessed individually rather than assumed to have identical internal construction or mechanical characteristics.

During our timegrapher inspection, the movement demonstrated favorable initial operating results. The recorded daily rate falls within our usual pre-shipment QC reference range of 0–15 seconds of daily deviation.

The amplitude and beat error also provide useful information about the movement’s condition during testing.

Although this is a lower-configuration version, its initial timekeeping results were satisfactory. A higher movement specification does not automatically guarantee better performance in every individual sample.

3. Verified Day and Date Functions

Both calendar displays were checked during our inspection.

Dial Position Verified Function
3 o’clock Date display
12 o’clock Weekday display

The date and weekday functions operated during testing.

These checks establish the basic operation of the two calendar displays on the inspected watch. They do not constitute a long-term assessment of calendar switching or movement durability.

4. Weighted Case and Physical Construction

An important feature of this QF Factory version is its weighted construction.

The watch has a substantial feel relative to its 36mm case size, giving it a noticeably different handling character from lighter configurations.

Its rose-gold-style exterior, brown dial and Roman numeral markers create a traditional Day-Date appearance.

The physical measurements provide useful reference points for comparing this 2836 version with other QF Factory Day-Date configurations.

5. Internal Precious-Metal Hallmarks

During inspection, precious-metal-style hallmarks were observed inside both the case and the clasp.

These markings are relevant visual details when examining the exterior construction and finishing of this version.

However, the presence of hallmarks does not establish that the case or bracelet is made from solid precious metal. Material composition must be assessed separately from decorative markings.

For this reason, the watch is described as having a rose-gold-style exterior rather than verified solid rose-gold construction.

6. Overall QC Assessment

The QF Factory Rolex Day-Date 128235-0075 is a more basic movement configuration within the factory’s weighted Day-Date range.

Its principal strengths are the substantial weighted construction, traditional brown Roman numeral dial, functioning day-date displays and satisfactory initial timekeeping results.

The main consideration is the movement configuration. Buyers comparing the 2836 and 3255-style versions should understand that they represent different mechanical platforms and potentially different levels of refinement.

For those who prioritize the weighted exterior and classic Day-Date appearance over a higher movement configuration, this version is worth considering.

Frequently Asked Questions

1. What movement does the QF Factory Day-Date 128235-0075 use?

This version uses a 2836 automatic movement operating at 28,800 BPH.

2. What is the main difference between the 2836 and 3255-style versions?

The primary difference is the movement platform. They should be compared based on their specific construction, features and tested performance rather than assuming identical mechanical characteristics.

3. Do the weekday and date functions work?

Yes. Both the weekday display at 12 o’clock and date display at 3 o’clock operated during our inspection.

4. Does the watch contain solid rose gold?

The inspected watch has a rose-gold-style exterior with internal precious-metal-style hallmarks. These markings alone do not establish solid gold content.

5. How much does the watch weigh?

The inspected sample weighed 159.2g.

6. Is the 2836 version worth considering?

Yes, particularly for buyers who value the weighted case and traditional Day-Date appearance while accepting a more basic movement configuration.
