THB Factory Audemars Piguet Royal Oak 15416CE Openworked Pre-Shipment QC Review
THB Factory Audemars Piguet Royal Oak 15416CE Openworked Pre-Shipment QC Review
The THB Factory Audemars Piguet Royal Oak Double Balance Wheel Openworked 15416CE.OO.1225CE.01 features a full ceramic construction, 41mm-class case and skeletonized openworked dial, paired with a Cal.3132 movement.
This model places particular emphasis on the visible movement architecture and openworked design, so movement presentation and exterior finishing are especially important parts of the pre-shipment inspection.
During this specific QC test, the Cal.3132 movement recorded +7 seconds/day, 274° amplitude, 0.2ms beat error and 21,600 BPH.
The actual watch measured 41.1mm in width, 9.8mm in thickness and 133.5g in weight, with a sapphire crystal.

These measurements were recorded from this specific watch during pre-shipment QC. Minor differences can occur between individual watches due to power reserve, production tolerances, testing position and measurement methods.
Cal.3132 Movement Performance
This THB Factory Royal Oak 15416CE is equipped with a Cal.3132 movement.
The timegrapher recorded:
Daily Rate: +7 seconds/day
Amplitude: 274°
Beat Error: 0.2ms
Beat Rate: 21,600 BPH
The +7 seconds/day reading falls within the commonly used ±0–15 seconds/day QC reference range.
The movement recorded a 274° amplitude, while beat error measured 0.2ms. These readings provide a useful reference for the operating condition of this specific movement at the time of testing.
Actual daily accuracy can vary depending on power reserve, temperature, resting position and wearing conditions.
Double Balance Wheel Openworked Design
The defining feature of the 15416CE is its Double Balance Wheel Openworked-style architecture.
Unlike a conventional closed dial, the skeletonized layout leaves a large portion of the movement structure visible from the front.
This makes visual QC particularly important.
The visible movement components, bridges, gears, balance area, hands, hour markers and surrounding structure should all be inspected carefully because small finishing or assembly differences are much easier to see through an openworked dial.
For this type of watch, movement presentation is therefore an important part of the overall appearance rather than simply an internal mechanical component.
Full Ceramic Construction
This version features full ceramic construction, including the case and bracelet.
Ceramic gives the Royal Oak a noticeably different appearance and feel compared with stainless-steel versions.
For QC purposes, particular attention should be given to the condition of the ceramic surfaces, edges, bracelet links and connection points.
Because the Royal Oak design combines multiple brushed and polished-looking surfaces with sharp geometric transitions, consistency across the case and bracelet has a significant influence on the overall appearance.
Ceramic components should also be handled carefully because, although highly resistant to surface scratches, they behave differently from steel under strong impact.
41.1mm Actual Width
The actual measured width of this specific QC sample is 41.1mm.
Although the model is generally categorized as a 41mm Royal Oak, individual physical measurement provides a more precise reference for the specific watch being inspected.
Small differences between nominal size and actual measurement can occur depending on the exact measuring position and production tolerances.
For this watch, 41.1mm is the actual recorded QC measurement.
9.8mm Measured Thickness
One of the more interesting physical measurements of this THB Factory 15416CE is its 9.8mm thickness.
Combined with the 41.1mm width, this gives the watch a relatively slim profile for a mechanically complex openworked sports-watch design.
Thickness is especially useful when comparing different Royal Oak factory versions because small differences can noticeably change the side profile and overall wrist presence.
The 9.8mm figure represents this specific QC sample.
133.5g Measured Weight
The measured weight of this specific watch is 133.5g.
Because this version uses full ceramic construction, its total weight and weight distribution differ from comparable full-steel Royal Oak configurations.
However, weight should not be treated as a standalone indicator of quality.
The case construction, bracelet articulation, dimensions, movement, clasp and overall balance on the wrist should all be considered together.
The 133.5g measurement applies to this specific QC watch, and small differences may occur between individual samples.
Sapphire Crystal and Openworked Details
This version is fitted with a sapphire crystal.
The openworked design makes clarity particularly important because much of the visual appeal comes from viewing the movement architecture through the front of the watch.
During exterior QC, attention should be given to the crystal condition, hands, hour markers, visible movement components, bezel alignment and ceramic surfaces.
The open architecture should also be inspected under several lighting angles because reflections and shadows can make the movement details appear noticeably different.
Ceramic Bracelet and Clasp QC
The integrated bracelet is an essential part of the Royal Oak design.
For a full-ceramic version, QC should include the individual bracelet links, articulation between links, surface consistency and connection between the bracelet and case.
The clasp should also be physically opened and closed to confirm secure locking and smooth operation.
Because ceramic cannot be treated exactly like stainless steel, checking the bracelet for visible chips or edge damage before shipment is particularly important.
Overall QC Assessment
This THB Factory Audemars Piguet Royal Oak Double Balance Wheel Openworked 15416CE.OO.1225CE.01 recorded:
+7 seconds/day
274° amplitude
0.2ms beat error
21,600 BPH
Actual physical measurements were:
Width: 41.1mm
Thickness: 9.8mm
Weight: 133.5g
Crystal: Sapphire
Construction: Full Ceramic
Movement: Cal.3132
The main characteristics of this version are the combination of its full ceramic construction, skeletonized openworked presentation and Cal.3132 movement.
The 41.1mm × 9.8mm measured dimensions are particularly useful reference points when comparing this model with other Royal Oak Openworked versions.
For this type of watch, QC should not focus solely on timegrapher results. The visible movement structure, ceramic case and bracelet finishing, alignment, clasp operation and overall assembly are equally important parts of the inspection.
Based on this specific test, the movement recorded stable readings, while the actual dimensions and weight provide useful real-world reference data for this THB Factory 15416CE.
