YF Factory Chopard Happy Diamonds 36mm ETA 956.102
The YF Factory Chopard Happy Diamonds is a 36mm quartz watch distinguished by its signature seven freely moving diamonds, which move around the dial as the watch changes position on the wrist.
This YF configuration uses an ETA 956.102 quartz movement, a 36mm round case, a blue crystal-set crown at 3 o’clock, and an imported American alligator leather strap with a quick-release system.
The supplied specification also lists 50 meters of water resistance.
36mm Case
The watch uses a 36mm round case, providing enough space for the moving-diamond construction while maintaining relatively compact proportions.
The circular architecture is particularly important to the Happy Diamonds design because the seven mobile diamonds require a defined track around the dial in which they can move freely.
Seven Moving Diamonds
The defining feature of this model is its seven moving diamonds.
Rather than being fixed directly to the dial or bezel, the diamonds are individually contained within the watch’s display structure and can move as the wrist changes position.
This creates a continuously changing arrangement around the dial.
The mobile-diamond construction is therefore not simply a decorative pattern—the movement of the individual stones is a central part of the watch’s visual design.
Mother-of-Pearl Dial
The dial incorporates a mother-of-pearl appearance, producing natural variations in reflection depending on the viewing angle and surrounding light.
Rather than displaying one completely uniform tone, mother-of-pearl can present subtle changes in brightness and color.
Together with the seven moving diamonds, this creates a dial whose appearance changes noticeably as the watch moves under different lighting conditions.
ETA 956.102 Quartz Movement
One of the most important specifications of this YF version is the ETA 956.102 quartz movement.
Unlike an automatic mechanical movement, the ETA 956.102 uses quartz regulation and battery power.
For this reason, the movement does not require daily winding or energy generated through wrist movement.
The specific ETA 956.102 designation is also useful when comparing this YF configuration with other Happy Diamonds versions that may use different quartz movements.
Blue Crystal-Set Crown
The crown is positioned at 3 o’clock and incorporates a blue crystal-style insert.
The blue detail creates a visual contrast against the surrounding case and provides another recognizable exterior feature of this configuration.
Quick-Release Alligator Leather Strap
The watch is supplied with an imported American alligator leather strap.
A quick-release mechanism is incorporated into the strap attachment, allowing the strap to be removed without relying on a conventional external spring-bar tool for routine changes.
This is particularly useful when alternating between different strap configurations.
50-Meter Water Resistance
The supplied YF specification lists the watch with a 50-meter water-resistance rating.
Water resistance should nevertheless be treated as dependent on the actual sealing condition of the individual watch, including the crown, crystal, caseback, and gaskets.
For regular use, water resistance should be verified by pressure testing if exposure to water is expected.

Moving Diamond Architecture
The seven mobile diamonds are the most distinctive structural element of this model.
Each diamond can change position as the watch moves, meaning the visual arrangement around the dial is never completely static.
This produces a very different effect from watches where diamonds are permanently set into the bezel or hour markers.
Combined with the reflective dial surface, the moving stones create changing highlights depending on wrist position and lighting.
Quartz Movement vs. Automatic Movement
The ETA 956.102 quartz movement also separates this version from mechanical watches with a similar luxury-oriented exterior design.
A quartz movement regulates time electronically through a quartz oscillator rather than using a mechanical balance wheel and escapement.
This provides a different ownership and maintenance experience from an automatic mechanical watch.
There is no automatic rotor and no need to keep the watch moving to maintain its power reserve.
36mm Wearing Proportions
At 36mm, the case sits between very compact traditional women’s watch dimensions and larger contemporary designs.
The circular case also provides sufficient visual space for the seven mobile diamonds without requiring an oversized case.
Combined with the leather strap, the overall construction remains relatively streamlined around the wrist.
