CBD Factory Rolex Day-Date 40mm Weighted 210g 3255
The CBD Factory Rolex Day-Date 40mm is a weighted 40mm configuration with an overall supplied weight of approximately 210g, a 25-link bracelet, and a 3255 automatic mechanical movement configuration.
One of the main characteristics of this CBD version is its weighted construction. According to the supplied factory specification, CBD uses what it describes as an “Oyster alloy” for its weighted components rather than relying solely on conventional tungsten-based weighting methods.
A free-sprung movement version is also available as a separate configuration. Because the free-sprung option is more expensive, customers interested in this version should contact customer service before ordering to confirm current pricing and availability.
40mm Day-Date Case
The CBD version uses a 40mm Day-Date case.
For this configuration, one of the most important specifications is not simply the external case diameter but the overall mass of the complete watch.
The supplied weight is approximately:
210g
This gives the CBD version a substantially weighted construction and provides a measurable specification when comparing it with other Day-Date versions.
Approximately 210g Total Weight
The CBD Factory Day-Date 40mm has a supplied total weight of approximately 210 grams.
Weight is particularly relevant when comparing different Day-Date configurations because watches with similar external dimensions can feel very different depending on the materials and internal construction used.
However, the number on the scale does not tell the entire story.
The distribution of mass between the case, caseback, bracelet links, and clasp can significantly influence wrist balance.
Two watches with similar total weights may therefore feel different when worn if their additional mass is concentrated in different areas.
CBD “Oyster Alloy” Weighted Construction
CBD describes the material used for this weighted version as Oyster alloy.
This should be treated as a CBD Factory-specific material designation.
Without an independent metallurgical analysis or detailed material-composition report, the exact percentages and constituent metals of this alloy cannot be independently confirmed.
For this reason, the most technically accurate description is:
CBD-designated Oyster alloy weighted construction.
This also avoids confusing CBD’s material terminology with Rolex’s own Oystersteel specification.
Why Material Density Matters
A weighted watch needs to increase mass without dramatically changing the external dimensions of the case and bracelet.
Material density therefore plays an important role.
When two components have similar volume, the component made from the higher-density material can have greater mass.
This is one reason different manufacturers use specialized alloys, high-density components, or modified internal structures when developing weighted watch versions.
For the wearer, however, total mass and mass distribution should be considered together.
Weighted Construction vs. Conventional Steel Construction
A conventional steel watch of similar dimensions generally has a different mass profile from a specially weighted configuration.
The CBD version is designed specifically around increased overall weight.
The approximately 210g total weight therefore provides a useful objective reference when comparing this version with lighter configurations.
Rather than describing the watch simply as “heavier,” recording the actual supplied weight makes future comparisons between different factories and versions more meaningful.
About Tungsten and Other High-Density Materials
Weighted watches can be manufactured using a variety of high-density materials and alloys.
These may include tungsten-containing alloys and other specialized metal combinations.
The performance of a finished component cannot be determined simply from whether it contains tungsten, nickel, copper, iron, silver, or another individual element.
Factors including:
* Alloy composition
* Manufacturing method
* Component structure
* Surface treatment
* Corrosion resistance
* Material quality
* Quality control
all influence the performance of the finished component.
For this reason, broad claims that one individual metal automatically makes a weighted component unsafe, unstable, or prone to failure are not technically sufficient for evaluating a finished watch.
25-Link Bracelet
The CBD Day-Date 40mm is supplied with a 25-link bracelet.
Bracelet construction is particularly important on a weighted watch because the bracelet contributes significantly to both overall mass and wrist balance.
A well-distributed increase in mass can feel different from a construction where most of the additional weight is concentrated inside the watch head.
For this reason, the 25-link bracelet specification and approximately 210g total weight should be considered together when evaluating the physical characteristics of this CBD configuration.
3255 Automatic Mechanical Movement
The standard CBD configuration uses a 3255 automatic mechanical movement.
The movement is configured for the Day-Date layout and provides automatic winding during normal wrist movement.
For technical accuracy, the supplied information does not establish that this is a genuine Rolex-manufactured Calibre 3255.
It should therefore be treated as a 3255 movement configuration rather than described as an original Rolex manufacture movement.
Free-Sprung Movement Version
CBD also offers a free-sprung movement version as a separate configuration.
A free-sprung balance architecture differs from a conventional regulated balance because rate adjustment is handled through the balance system rather than a traditional regulator arrangement.
For customers specifically looking for the free-sprung configuration, it is important to confirm the movement version before ordering.
The free-sprung version is more expensive than the standard configuration, and pricing may vary depending on current supply.
For this reason:
Please contact customer service for current free-sprung movement pricing and availability before ordering.
Standard vs. Free-Sprung Configuration
The standard 3255 configuration and the optional free-sprung configuration should not be treated as identical versions.
The difference is specifically related to the movement architecture.
Customers whose priority is the free-sprung balance system should confirm that option when placing the order rather than assuming every CBD Day-Date 40mm uses the same movement configuration.
This also helps prevent confusion when comparing different listings or batches of the same model.

Weight Distribution and Wrist Balance
The 210g measurement is useful because it provides an objective reference, but total weight alone should not be used to judge the complete wearing experience.
Weight distribution also matters.
Additional mass may be distributed through several areas:
Case → Caseback → Bracelet → Clasp
If the majority of the additional weight is concentrated in the watch head, the watch can feel more top-heavy.
If the mass is distributed more evenly through the case and bracelet, the balance on the wrist can feel different even when the total measured weight is similar.
This is why both actual weight and construction method are useful when comparing weighted Day-Date versions.
CBD Version Characteristics
The main supplied specifications that distinguish this CBD configuration are:
40mm Day-Date case
Approximately 210g total weight
CBD-designated Oyster alloy weighted construction
25-link bracelet
3255 automatic movement configuration
Optional free-sprung movement version
These specifications provide clearer comparison points than subjective descriptions such as “best version” or “closest to original.”
Choosing Between the Standard and Free-Sprung Version
For customers mainly interested in the appearance, weight, and general Day-Date configuration, the standard 3255 version provides the basic CBD specification described on this page.
For customers specifically looking for a free-sprung balance architecture, the separate free-sprung version should be confirmed before ordering.
Because the free-sprung movement carries a higher price, customers should contact customer service to check the current price and availability before selecting this configuration.
Wearing and Care
At approximately 210g, this is a relatively heavy mechanical watch.
The additional mass may be noticeable during extended wear, particularly for users accustomed to lighter stainless-steel watches.
The crown and calendar functions should always be operated gently. If unusual resistance is encountered, do not force the mechanism.
Strong impacts and powerful magnetic fields should also be avoided.
Actual water resistance should be confirmed through pressure testing before intentional water exposure.

What movement does the CBD version use?
The standard version uses a 3255 automatic mechanical movement configuration.
Is a free-sprung movement available?
Yes. A free-sprung version is available as a separate option.
Is the free-sprung version the same price?
No. The free-sprung configuration is more expensive, so customers should contact customer service for current pricing and availability before ordering.
How many links does the bracelet have?
The supplied CBD configuration uses a 25-link bracelet.
Is 210g the only factor that determines wrist feel?
No. Although 210g provides an objective total-weight reference, the distribution of that weight between the case, bracelet, and clasp also influences balance and wrist feel.
Does the CBD version use conventional tungsten weighting?
The supplied CBD specification describes this version as using its Oyster alloy weighted construction rather than identifying it as a conventional tungsten-weighted configuration.
Are tungsten-containing materials necessarily unstable?
No. The performance of a finished component depends on its exact alloy composition, manufacturing process, structure, finishing, and quality control. The presence of tungsten alone does not determine whether a component is stable or unstable.
