The RSW LA122 Open Heart (Ref. RSWLA122-GL-12) is a Swiss Made women’s automatic watch that has been part of the brand’s contemporary production since the 2020s. Positioned within the accessible segment of Swiss mechanical watchmaking, it interprets the dress watch through a more decorative language, in which formal elegance and visible mechanics carry equal weight.
The model’s personality comes from the combination of a green dial, gold tones, diamonds, and an open-heart aperture. It is aimed primarily at those looking for a distinctive women’s automatic watch capable of revealing part of its mechanical operation without adopting the fully openworked architecture typical of a skeleton watch.
Design
The green dial forms the visual center of the composition. Its dark tone creates a strong contrast with the gold-colored elements and allows the applied indications to stand out clearly, while maintaining a less conventional character than the colors traditionally associated with a dress watch.
The large Arabic numerals at 3, 6, and 9 o’clock establish three main reference points, complemented by slender baton hour markers and a peripheral minute track. This arrangement leaves the upper portion of the dial free for the element that most strongly defines the model, preventing the visible mechanics from disrupting the overall balance.
The gold-colored hands adopt an angular, dauphine-inspired profile. The hour and minute hands have enough visual presence to stand apart from the background, while the central seconds hand introduces a slimmer and more dynamic element.
At 12 o’clock, the circular aperture effectively takes the place of the fourth cardinal reference and reveals the balance wheel and part of the regulating organ. The integration remains relatively restrained: the dial surface continues to dominate, while the visible mechanics create depth without turning the entire architecture into a skeletonized design.
The bezel adds a jewelry-inspired element through small diamonds individually set around its perimeter. The spaced arrangement leaves the gold-colored surface visible between each stone, creating distinct points of light rather than the continuous effect of a pavé setting.
The green genuine leather strap directly echoes the color of the dial and completes the overall chromatic continuity. This choice avoids a sharp contrast between the case and strap while reinforcing the green-and-gold identity that characterizes this configuration.
Case & Construction
The case is made from stainless steel with a gold-tone PVD coating and adopts a cushion-square shape with strongly rounded corners. It measures 34 × 34 mm, reaches approximately 37 mm diagonally, and has a thickness of 10 mm. The lug width is 15 mm, while the stated lug-to-lug measurement is 34 mm.
The construction avoids protective guards around the crown, which is positioned conventionally at 3 o’clock. This configuration is consistent with the watch’s elegant purpose, with none of the external elements typically associated with cases designed for professional or sporting use.
The upper surface is protected by a sapphire crystal. Water resistance is rated to 50 meters, equivalent to 5 ATM, a specification intended for the normal accidental exposure encountered in everyday use rather than deliberate aquatic activity.
Movement
The movement is the RSW Caliber RW24-S, a Swiss Made automatic mechanical caliber. The power reserve is stated at approximately 40–42 hours, a traditional figure that makes the movement better suited to frequent wrist rotation than to use interrupted by extended periods of inactivity.
The mechanical configuration remains deliberately simple and does not introduce additional functional complications. This essential approach is consistent with a model in which the caliber primarily serves as the mechanical foundation for timekeeping and for the kinetic component associated with the open-heart design.
Additional specifications such as frequency, jewel count, manual winding, and hacking seconds are not sufficiently documented. It is therefore preferable not to attribute these characteristics to the RW24-S as confirmed specifications in the absence of conclusive technical documentation.
Functions & Complications
The functions comprise hours, minutes, and central seconds. There is no date, calendar, or supplementary indication, so everyday interaction remains straightforward and the reading of the time is not divided among secondary displays.
The open heart represents the defining feature of this configuration, but it is not a mechanical complication in the strict sense because it does not add a new function to the caliber. Instead, it is a display solution that allows part of the regulating organ to be observed directly while the movement is running.
Performance
On the wrist, the case sits compactly and concentrates its presence around the central area. The cushion-square shape occupies visual space differently from a circular case, but the rounded corners soften its geometry and maintain a balanced profile.
The short lugs limit longitudinal extension and help the watch conform to smaller wrists without creating pronounced overhang at the extremities. The frontal geometry nevertheless retains a recognizable presence, making the watch appear more substantial than a simple reading of its proportions might suggest.
The relatively narrow strap maintains a coherent visual relationship with the case and naturally complements its scale. The butterfly deployant clasp distributes the opening across both sides and reduces the repeated bending of the leather normally associated with using a traditional pin buckle.
The profile remains suitable for wear beneath a cuff without creating excessive vertical bulk. Wrist presence therefore comes primarily from the shape and strong chromatic identity, while the overall architecture retains a discreet ergonomic character.

The RSW LA122 Open Heart occupies a specific niche among women’s automatic dress watches: it favors simple mechanics within a design in which visual expression plays a central role. It seeks neither the neutrality of a traditional elegant timepiece nor the dramatic complexity of a fully skeletonized watch.
One of its main strengths is its design coherence. The decorative elements do not appear independent from one another but instead work together to define a distinctive interpretation of the contemporary dress watch. The visible mechanics also introduce a dynamic element to an approach that would otherwise be predominantly aesthetic.
Its main limitation is precisely its reduced stylistic versatility. The strong character makes the model less adaptable than a more restrained dress watch, while its essential functional specification offers little incentive if you are looking for greater horological complexity. Its autonomy also belongs to a more traditional generation of automatic calibers and does not represent a competitive advantage over contemporary long-power-reserve solutions.
The price-to-quality ratio should therefore be considered in terms of the overall proposition rather than the mechanics alone. The Swiss construction, decorative approach, and distinctive integration of visible mechanics are the elements on which the product’s value is centered; if you prioritize caliber performance and functional richness instead, you will find more suitable alternatives.
The verdict is that of a dress watch with a clearly defined and deliberately selective personality. It works best if you are looking for an elegant yet unconventional women’s automatic watch in which the mechanics contribute to the visual experience without dominating the design. Its strength lies not in universality, but in the coherence with which it develops a distinctive decorative identity.
