The Omega Constellation Ladies (Ref. 1591.71.00) is a women’s automatic watch from the 2000s, positioned within the luxury Swiss watchmaking segment. It interprets the design language of the Constellation collection through distinctly feminine proportions and an elegant approach, appealing to those looking for a compact mechanical timepiece with an immediately recognizable personality.
Its defining characteristic is the integration of the white mother-of-pearl dial with the collection’s signature architecture, where a Roman numeral bezel, lateral claws, and bracelet form a visually cohesive whole. It is therefore not simply a small dress watch, but a model in which the collection’s design remains central even within a particularly compact format.
Design
The white Mother-of-Pearl dial is the main decorative element. Mother-of-pearl replaces the uniformity of a traditional white background with a light-sensitive surface, capable of revealing pearlescent reflections and subtle chromatic variations depending on the viewing angle. The effect remains refined because the composition avoids overly intrusive graphic elements.
The applied hour markers feature a distinctive pyramidal geometry, almost diamond-like in shape. Their angled surfaces catch the light and create small points of brilliance, adding depth without relying on decorative gemstones. The slender, linear central hands, meanwhile, maintain a discreet appearance and allow the mother-of-pearl to remain the visually dominant element.
A substantial part of the graphic information is transferred to the bezel. The dark Roman numerals mark the outer perimeter and create a strong contrast with the metal, freeing the dial from the need for a particularly prominent minute track. The four characteristic claws interrupt the continuity of the circumference and give the front of the watch a distinctive appearance immediately associated with the Constellation line.
The bracelet completes the design through broad horizontal links that extend directly from the lines of the watch. The continuity between the central body and the bracelet creates a more architectural appearance than that of a traditional elegant model with a separate strap, contributing decisively to its overall identity.
Case & Construction
The case is made of stainless steel and measures approximately 27.5 mm in diameter, with a thickness of around 8.8 mm and a lug-to-lug distance of approximately 31 mm. A conventional lug-width measurement does not apply because the attachment points are incorporated into the architecture of the integrated bracelet.
The bezel is fixed and incorporates the four lateral elements characteristic of the collection. This configuration creates a construction different from that of a traditional round case with projecting lugs, concentrating the structure around a compact central body.
The dial is protected by a sapphire crystal, while the caseback is made of steel. The stated water resistance is 30 meters, equivalent to 3 ATM, a rating consistent with predominantly everyday and formal use rather than aquatic activities.
On examples currently available on the pre-owned market, the original water-resistance rating does not guarantee their present condition. Gasket integrity and the result of a pressure test therefore become practical factors to verify before exposing the timepiece to water.
Movement
The engine is the Omega Caliber 2520, a Swiss Made automatic mechanical movement with a 42-hour power reserve. This is the component that gives the model its distinctly mechanical character within a category where, particularly in the compact feminine proportions typical of the period, quartz configurations were also widespread.
The choice of caliber therefore plays an important role in the identity of the watch: the design does not treat the mechanical movement as a merely secondary element, but integrates it into a construction that retains very compact dimensions.
For an example belonging to this generation, technical evaluation today depends primarily on the actual condition of the movement and its service history. A documented service and proper operation of the caliber have greater practical importance than attributing secondary specifications that have not been sufficiently verified for this particular configuration.
Functions & Complications
The functional equipment includes hours, minutes, and central seconds, while automatic winding maintains the available power during use. The only complication is the date display positioned at 3 o’clock.
The date window features a metal frame that clearly separates the numerical indication from the surrounding iridescent surface. Its peripheral position preserves the cleanliness of the central area and allows immediate reading without introducing additional scales or secondary displays.
The functional configuration therefore remains deliberately essential: there are no additional complications.
Performance
On the wrist, the timepiece maintains a deliberately restrained presence and follows the traditional concept of compact women’s watchmaking. The case sits close to the wrist, remains discreet beneath a cuff, and favors an elegant profile rather than a pronounced presence on the arm.
Its ergonomic behavior is influenced primarily by the first links, which extend outward before articulating around the wrist. This solution visually distributes the watch along the arm and prevents the central body from appearing isolated, creating a more continuous presence than that of a small model fitted with a conventional strap.
The integrated construction makes proper bracelet adjustment particularly important. On a pre-owned example, play between the links, smoothness of articulation, condition of the clasp, and availability of any additional links required for a proper fit therefore deserve close attention. In this case, the bracelet is not an easily interchangeable accessory, but a component that plays a decisive role in ergonomics.
Legibility favors daytime use and well-lit environments. The dial configuration is oriented toward elegance and does not make nighttime visibility a central part of the wearing experience.

This Omega Constellation Ladies consistently interprets the women’s watchmaking of its era without simply reducing the proportions of a men’s model. Its personality comes from a design conceived as a cohesive whole, in which every component contributes to a clearly defined collection identity.
Its limitations become most apparent when compared with contemporary expectations for everyday use. Its predominantly formal character reduces versatility compared with a modern everyday watch, while the age of available examples makes condition a decisive factor. The distinctive bracelet construction also requires attention when purchasing, as wear, adjustment, and completeness directly affect usability.
Value for money should therefore be assessed on the individual example rather than simply on the model’s average market price. Originality, overall condition, proper operation, and service history can justify significant differences between two apparently equivalent watches; an especially low price becomes less attractive when it anticipates major servicing or difficult-to-resolve issues.
The ideal buyer is someone looking for a women’s Swiss automatic watch from the 2000s with traditionally compact proportions and who places particular value on the design language of the Constellation family. If you prioritize greater water resistance, longer autonomy, or sporting versatility, more suitable modern alternatives are available.
The overall verdict is positive: the model retains a distinct identity and an appeal that extends beyond the prestige of the brand itself. Its value lies above all in being a genuinely feminine mechanical watch conceived around compact proportions and a clearly defined collection design, qualities that continue to distinguish it within the pre-owned market.
