THB Factory Cartier Santos 39.8mm – 9015 Movement and Rubber Strap Guide
The THB Factory Cartier Santos combines the recognizable Santos case design with a rubber-strap configuration and 9015 automatic mechanical movement.
According to the supplied specifications, the case measures approximately 39.8mm × 47.5mm with a thickness of 9.08mm.
Beyond the dimensions, several details are worth looking at more closely: the 316L stainless-steel case, blue hands, faceted blue crown insert, fluororubber strap and the SmartLink / QuickSwitch-style strap-changing system.
Together, these features make this version quite different in character from a conventional Santos fitted only with a steel bracelet.
39.8mm × 47.5mm Case
The supplied dimensions are:
Width: 39.8mm
Length: 47.5mm
Thickness: 9.08mm
With the Santos, width alone does not fully describe how the watch will sit on the wrist.
The case has a relatively square profile with extended lugs and an integrated transition into the strap, so the 47.5mm overall length and 9.08mm thickness are also useful measurements when considering wrist fit.
The relatively slim profile is particularly relevant because excessive thickness can noticeably change the proportions of this case design.
316L Stainless-Steel Case
The case is specified as 316L stainless steel.
The Santos design combines broad flat surfaces with defined edges, making surface finishing especially visible under direct lighting.
Useful areas to examine include the bezel, case sides, lug transitions and the areas surrounding the exposed screws.
Rather than judging the case from a single front photograph, angled images are useful for showing how the different surfaces and edges interact.
Santos Dial Design
The dial retains the familiar Santos layout with large Roman numerals and a relatively open central area.
Because the design is visually simple, small alignment differences can become more noticeable.
Useful details include:
- Roman numeral printing
- Minute track
- Hand alignment
- Dial centering
- Hand clearance
- Overall printing consistency
A straight-on photograph is particularly useful for checking symmetry and alignment.
Blue Hands
The supplied version uses heat-blue-style hands.
Blue hands are one of the most recognizable visual elements of the Santos design, particularly against a lighter dial.
The color can change noticeably depending on the angle of the light. Under some conditions the hands may appear bright blue, while from another angle they can look considerably darker.
For this reason, several lighting angles provide a more useful impression than judging the color from one photograph.
Crystal and Anti-Reflective Treatment
The supplied information describes the crystal as having an anti-reflective surface treatment intended to reduce glare and visible fingerprints.
Rather than treating those claims as absolute, the crystal can be evaluated practically under direct and angled lighting.
Reflection, clarity and any visible coating characteristics are easier to assess this way.
Blue Crown Detail
The crown incorporates a faceted blue stone-style insert, another characteristic visual element of the Santos design.
Because the crown sits prominently against the polished steel case, its shape, positioning and color are relatively easy to notice.
The crown should also be tested functionally.
Manual winding, time setting and the transition between the available crown positions should operate normally without unusual resistance.
Fluororubber Strap
This THB configuration is supplied with a fluororubber strap.
Compared with a steel bracelet, rubber changes both the visual character and wrist feel of the Santos.
The strap should remain flexible while sitting naturally against the case and wrist.
Useful areas to inspect include the strap edges, surface texture, attachment points and the transition between the strap and case.
Correct sizing is also important because a rubber strap can affect how securely the relatively broad Santos case remains centered on the wrist.
QuickSwitch-Style Strap System
One of the more practical features of this version is its QuickSwitch-style quick-release system.
The idea is straightforward: compatible straps can be removed and installed without using a conventional spring-bar tool.
For someone who alternates between steel and rubber configurations, this can make strap changes considerably easier.
The important point is not simply whether the mechanism releases.
After reinstalling the strap, both sides should lock securely into the case without excessive play.
The strap should then be gently checked to confirm that the locking mechanism has fully engaged before the watch is worn.
SmartLink-Style System
The supplied information also references a SmartLink-style adjustment system associated with the bracelet configuration.
SmartLink and QuickSwitch serve different purposes.
QuickSwitch relates to removing and replacing the complete strap or bracelet.
SmartLink relates to bracelet-link adjustment.
Keeping these two mechanisms separate makes the configuration easier to understand.
9015 Automatic Movement
Inside this THB Santos is a 9015 automatic mechanical movement.
The 9015 provides automatic winding together with the normal time-setting functions required by this configuration.
Rather than focusing only on the movement name, an individual movement is better evaluated through actual operation and timegrapher testing.
Useful measurements include:
Daily Rate → Amplitude → Beat Error → Beat Rate
Manual winding, automatic winding and crown operation can then be tested separately.
Movement Architecture and Exterior Accuracy Are Separate
The use of a 9015 movement should also be understood separately from the exterior construction of the watch.
Case dimensions, dial appearance and strap mechanisms describe the exterior configuration, while the 9015 identifies the underlying movement platform.
This distinction is particularly useful when comparing a super clone watch, because similar-looking versions may use different internal movement architectures.
For actual movement measurements, case dimensions and functional testing from an individual example, see our THB Factory Cartier Santos QC test.
Details Worth Checking
For an individual THB Santos, the supplied 39.8mm width and 9.08mm thickness are useful measurements to verify first.
The dial can then be checked for Roman numeral printing, hand alignment and the appearance of the blue hands under different lighting angles.
The rubber strap should fit naturally against the case.
More importantly, the QuickSwitch-style mechanism should be released and reinstalled to confirm that both sides lock correctly.
The crown can then be tested for winding and time setting.
Finally, the 9015 movement can be measured for daily rate, amplitude, beat error and beat rate to provide an actual record of its running condition.

- Can the rubber strap be removed without tools?
The supplied configuration uses a QuickSwitch-style system designed to allow compatible straps to be removed and installed without a conventional spring-bar tool.
- What is the difference between QuickSwitch and SmartLink?
QuickSwitch is used to change the complete strap or bracelet, while SmartLink is associated with adjusting bracelet links.
- Can THB straps and components be guaranteed to interchange with genuine Cartier parts?
The supplied material makes interchangeability claims, but this should be confirmed through actual fitting before being treated as guaranteed compatibility. Small manufacturing tolerances can affect whether individual components fit correctly.
- What should be checked on an individual THB Santos?
Useful checks include actual dimensions, movement rate, amplitude, beat error, beat rate, dial and hand alignment, crown operation, rubber-strap fit and QuickSwitch-style locking security.
