OMEGA 1959 / Constellation / Cal. 561

Introducing the 1959 Omega "Constellation".

The "Constellation" is Omega's flagship line, born in 1952, and is known as a chronometer series that constantly pursues the highest precision.

As its name, meaning "constellation," suggests, the star on the dial and the observatory medallion on the case back symbolize its status, and it has been highly regarded as Omega's representative dress watch since its birth.

■ Dial/Case Design

This Constellation features a dial that has aged to a soft ivory tone, showcasing the calm expression unique to a piece that has endured for many years.

The dial combines chamfered applied bar indexes with a three-dimensional Omega logo at 12 o'clock and sharp dauphine hands, exuding a strong sense of dignity within its simple composition.

The "Constellation" inscription in cursive and a star mark are placed at 6 o'clock.
It naturally creates the impression of high quality characteristic of this model, without relying on excessive ornamentation.

Furthermore, a charming feature of this particular piece is the presence of cross-hairs on the dial.
The delicate vertical and horizontal lines balance the entire dial and offer excellent legibility, making it easy to discern the relative positions of each index.
Constellation models with cross-hairs are limited in number, adding a subtle touch of individuality to this model.

The case features a clean round form as its base, with lugs that extend sharply to the tips, creating an impressive design.

The bezel is slender, making the dial look neat and giving the whole watch an elegant and refined impression.
The lines connecting the side of the case to the lugs are also smooth, emphasizing a smart silhouette.

The case back features the observatory medallion, a symbol of the Constellation.
Even unseen, the charm characteristic of this model is firmly present.

■Movement

The movement is the Cal.561, an automatic movement with 24 jewels.

The Cal.561 is one of Omega's automatic chronometer movements, developed for high precision at the time. It features 24 jewels, a frequency of 19,800 vibrations per hour, and stable winding efficiency through bidirectional winding.

It is a machine that supported the high precision and practicality suitable for the Constellation, and it is an indispensable existence when discussing the perfection of Omega's automatic movements. Within its understated exterior, Omega's reliable technical prowess of the era is firmly alive.

■Styling

Case size: 42.8mm (length), 36.3mm (width), 11mm (thickness), Weight: 71g.
