GH Factory Jaeger-LeCoultre Master Control 38mm Cal.899
The GH Factory Jaeger-LeCoultre Master Control is a 38mm automatic mechanical watch featuring a slim 8.4mm case profile, an integrated-style metal bracelet, a sunburst-brushed dial, and a Cal.899-style automatic movement.
Its design focuses on relatively compact proportions and a clean three-hand dial architecture, while the integrated bracelet combines polished and satin-brushed surfaces to create contrast across the exterior finishing.
With a case measuring 38mm in diameter and 8.4mm in thickness, this GH configuration is notably slimmer than many contemporary automatic watches.
38mm Case
The watch uses a 38mm case with a thickness of 8.4mm.
These dimensions are an important part of this model’s overall design.
Rather than using a large case to create wrist presence, the 38mm diameter keeps the proportions relatively restrained, while the 8.4mm thickness produces a slim side profile.
This combination also allows the watch to sit closer to the wrist than thicker automatic mechanical configurations.
8.4mm Slim Case Profile
At 8.4mm thick, case thickness is one of the most useful specifications for distinguishing this GH version.
Thickness influences more than appearance. It also affects how the case sits on the wrist and how easily the watch fits beneath a shirt cuff.
Viewed from the side, the relatively slim profile also places greater visual emphasis on the relationship between the case, bezel, and integrated bracelet.
Clean Three-Hand Dial
The dial follows a relatively restrained three-hand layout, keeping the primary time indications clearly separated.
Rather than relying on numerous complications, the design places greater emphasis on proportions, hour markers, hands, and surface finishing.
This provides a noticeably different visual character from more complicated Jaeger-LeCoultre models such as the Master Geographic, Master Calendar, or perpetual-calendar configurations.
Sunburst-Brushed Dial
The dial incorporates a radial sunburst-brushed finish.
Fine lines extend outward from the center of the dial, causing the surface to reflect light differently depending on the viewing angle.
Under direct and indirect lighting, this can produce variations in brightness across different sections of the dial without requiring additional decorative elements.
The finishing therefore forms an important part of the otherwise minimalist dial architecture.
Integrated-Style Bracelet
One of the most distinctive exterior features of this GH configuration is its integrated-style metal bracelet.
Rather than creating a strong visual separation between the case and bracelet, the bracelet follows the lines of the case into the wrist.
This creates a more continuous profile when the watch is viewed from the front or side.
Polished and Satin-Brushed Finishing
The bracelet combines high-polished and satin-brushed surfaces.
Alternating these two finishing techniques creates visual separation between individual bracelet surfaces and links.
Polished sections reflect light more directly, while the satin-brushed areas produce a softer appearance.
This contrast becomes particularly noticeable as the bracelet moves around the wrist.
Cal.899-Style Automatic Movement
The GH version is supplied with a Cal.899-style integrated automatic mechanical movement.
Automatic winding allows normal wrist movement to contribute energy to the mainspring during regular wear.
For technical accuracy, this movement should not be described as a genuine Jaeger-LeCoultre manufacture Calibre 899 unless its origin can be independently established.
The appropriate description for this configuration is therefore:
Cal.899-style automatic mechanical movement.
This distinguishes the movement architecture used by the GH version from an original Jaeger-LeCoultre manufacture movement.

Case and Bracelet Integration
The combination of a 38mm case and integrated-style bracelet is one of the most useful ways to distinguish this configuration from conventional leather-strap Master models.
The bracelet begins visually close to the case and continues the case geometry toward the wrist.
Its alternating polished and brushed surfaces add definition without changing the relatively restrained overall design.
The result is a different wearing profile from a conventional 38mm watch fitted with separate straight-end lugs and a leather strap.
38mm × 8.4mm Proportions
The combination of 38mm diameter and 8.4mm thickness is particularly relevant when evaluating this watch.
Diameter describes how much horizontal space the watch occupies on the wrist, while thickness determines its vertical profile.
A 38mm diameter keeps the overall footprint relatively compact, while the 8.4mm thickness maintains a slim case architecture.
These are more useful comparison points than subjective descriptions such as “perfect proportions” because both measurements can be directly compared with other versions.
GH Version Characteristics
The principal supplied specifications for this GH Factory configuration are:
38mm case diameter
8.4mm case thickness
Cal.899-style automatic movement
Three-hand dial architecture
Sunburst-brushed dial
Integrated-style bracelet
Alternating polished and satin-brushed finishing
Together, these characteristics provide the main technical and visual identifiers for this version.
Wearing and Care
The 38 × 8.4mm dimensions provide a relatively slim wearing profile, while the integrated bracelet distributes the watch across a wider area of the wrist.
Polished exterior surfaces can show fine marks more readily than brushed surfaces, so the watch should be cleaned with a clean, soft microfiber cloth.
As with other automatic mechanical watches, strong impacts and powerful magnetic fields should be avoided.
If intentional water exposure is expected, actual water resistance should be confirmed through pressure testing because no specific water-resistance rating has been provided for this configuration.
Frequently Asked Questions
What is the size of the GH Factory Master Control?
The supplied configuration measures 38mm in diameter and 8.4mm in thickness.
What movement does this GH version use?
It uses a Cal.899-style automatic mechanical movement.
Is this a genuine Jaeger-LeCoultre Calibre 899?
It should not be described as a genuine Jaeger-LeCoultre manufacture Calibre 899. The supplied GH version uses a movement configured around the Cal.899-style architecture.
Is this an automatic watch?
Yes. The supplied movement is an automatic mechanical movement.
What type of dial layout does it use?
The watch uses a relatively clean three-hand dial layout.
How is the dial finished?
The dial features a radial sunburst-brushed surface, which produces different reflections depending on the lighting and viewing angle.
What type of bracelet does this version have?
It uses an integrated-style metal bracelet that visually continues the lines of the case.
How is the bracelet finished?
The bracelet combines high-polished and satin-brushed surfaces.
Is 8.4mm considered an important specification for this version?
Yes. The 8.4mm case thickness is one of the main measurable characteristics of this GH configuration and contributes to its relatively slim profile.
What is the water-resistance rating?
A specific water-resistance rating was not provided in the supplied specifications, so one should not be assumed without an actual pressure test.
