8F Factory Vacheron Constantin Overseas Chronograph 5500V/110A-B148 Pre-Shipment QC Review

8F Factory Vacheron Constantin Overseas Chronograph 5500V/110A-B148 Pre-Shipment QC Review

The 8F Factory Vacheron Constantin Overseas Chronograph 5500V/110A-B148 features a 42.5mm-class case, blue dial, steel construction and rubber strap, paired with a modified 7750-based chronograph movement.

For this type of mechanical chronograph, movement testing is particularly important because the assessment should include not only timekeeping performance but also the actual start, stop and reset operation of the chronograph.

During this specific pre-shipment QC test, the movement recorded +8 seconds/day, 250° amplitude, 0.0ms beat error and 28,800 BPH.

The actual watch measured 42.1mm in width, 14.8mm in thickness and 146.5g in weight, with a sapphire crystal.

These measurements were recorded from this specific watch during pre-shipment QC. Small differences may occur between individual watches due to production tolerances, power reserve, testing position and measurement methods.

Modified 7750-Based Chronograph Movement

This 8F Factory Overseas Chronograph 5500V uses a modified 7750-based mechanical chronograph movement.

This is an important technical point when comparing different Overseas Chronograph versions.

The movement should be identified according to its actual underlying architecture rather than simply by the visual appearance of the movement or the reference it is designed to represent.

Because the 7750 is a chronograph platform, the actual operation of the chronograph should also be included in the QC process rather than relying solely on timegrapher readings.

Timegrapher Performance

The movement recorded:

Daily Rate: +8 seconds/day
Amplitude: 250°
Beat Error: 0.0ms
Beat Rate: 28,800 BPH

The +8 seconds/day result falls within the commonly used ±0–15 seconds/day pre-shipment QC reference range.

The movement recorded a 250° amplitude, while the beat error measured 0.0ms during this specific test.

These figures provide a useful record of the movement’s condition at the time of inspection.

Actual daily accuracy can vary depending on power reserve, temperature, resting position and wearing habits, so individual timegrapher readings should be considered together with functional testing.

Chronograph Function Testing

For the Overseas Chronograph 5500V, the chronograph is an important part of the mechanical functionality.

During pre-shipment QC, the chronograph should be physically tested through the complete:

Start → Stop → Reset

sequence.

The chronograph hands should operate normally during the test, and their return positions should be checked after reset.

The pushers should also be tested for normal operation without excessive resistance.

For a modified 7750-based movement, unnecessary repeated or aggressive operation of the chronograph should be avoided. Normal, controlled operation is preferable for long-term mechanical stability.

42.1mm Actual Width

Although the 5500V is generally categorized as a 42.5mm-class Overseas Chronograph, this specific QC sample measured 42.1mm in width.

Actual measurements can differ slightly from nominal model specifications depending on the measuring position and production tolerances.

This is why individual QC measurements provide useful real-world reference data when comparing different factory versions.

For this specific watch, the recorded width is 42.1mm.

14.8mm Measured Thickness

This specific watch measured 14.8mm in thickness.

Thickness is an important specification for a mechanical chronograph because the additional chronograph mechanism generally requires more vertical space than a simpler time-and-date movement.

Combined with the 42.1mm measured width, the 14.8mm thickness gives this model a relatively substantial sports-chronograph profile.

For buyers comparing different Overseas versions, thickness is therefore an important measurement to consider alongside case width.

146.5g Measured Weight

The actual measured weight of this specific QC sample is 146.5g.

This version combines a steel case with a rubber strap, so its total weight differs from a comparable full-steel bracelet configuration.

The weight should be evaluated together with the 42.1mm width, 14.8mm thickness, case construction and strap configuration.

The 146.5g figure represents this specific watch, and minor variations may occur between individual samples.

Blue Dial and Exterior Details

The blue dial is one of the defining visual characteristics of the 5500V/110A-B148 configuration.

Because blue dials can change noticeably under different lighting conditions, QC photos taken under several angles and light levels provide a more useful reference than a single static image.

Inspection should focus on the hands, hour markers, subdials, date display and printing, together with the overall dial alignment.

For a chronograph with multiple subdials, alignment is particularly important because even small differences can be visually noticeable.

Sapphire Crystal and Steel Case

This version is fitted with a sapphire crystal and stainless-steel case.

The sapphire crystal should be inspected for surface condition and clarity, while the steel case should be checked for scratches, finishing consistency and clean transitions between different surfaces.

The crown and chronograph pushers should also be inspected both visually and functionally.

Because the Overseas design combines a relatively complex case shape with an integrated-style strap connection, the transition between the case and rubber strap is another area worth checking during QC.

Rubber Strap and Clasp

This 5500V configuration uses a rubber strap, giving it a sportier wearing profile than the full-steel bracelet version.

During QC, the strap should be inspected for surface condition, fit at the case connection and overall alignment.

The clasp should also be opened and closed several times to confirm normal operation and secure locking.

For daily use, the strap and clasp are functional components rather than simply cosmetic details, so they should be included in the pre-shipment inspection.

Overall QC Assessment

This 8F Factory Vacheron Constantin Overseas Chronograph 5500V/110A-B148 recorded:

+8 seconds/day
250° amplitude
0.0ms beat error
28,800 BPH

Actual physical measurements were:

Width: 42.1mm
Thickness: 14.8mm
Weight: 146.5g
Crystal: Sapphire
Movement: Modified 7750-Based Chronograph

The main characteristics of this version are its blue dial, steel case, rubber strap and modified 7750-based chronograph movement.

The movement produced a 0.0ms beat error during this particular test, while the +8 seconds/day rate remained within the commonly used pre-shipment QC reference range.

For this model, timegrapher readings should not be considered alone. The chronograph start, stop and reset functions, hand reset positions, pushers, dial alignment, sapphire crystal, case finishing and strap connection should all be checked before shipment.

These actual measurements and movement readings provide useful reference data for buyers comparing different Overseas Chronograph 5500V versions.
