The Omega Cosmic Ref. 2486 represents one of the brand’s most intriguing yet quietly underappreciated achievements of the mid-20th century. Featuring a full calendar complication, it once stood among the most sophisticated offerings in Omega’s lineup, reflecting the technical ambition of the era.

Calendar-equipped Cosmics often fly under the radar, frequently overshadowed by more complex perpetual calendar models. Yet their charm lies precisely in this balance of practicality, elegance, and mechanical interest. This particular example elevates the reference even further, distinguished by an exceptionally rare dial configuration with day and month displays rendered in Farsi (Persian)—a detail seldom encountered and highly desirable among seasoned collectors.

Compact in concept yet rich in character, this watch offers the appeal of a calendar complication without the ostentation often associated with larger, more imposing counterparts. A refined and culturally significant piece, it stands as a fascinating alternative to the more celebrated calendar watches of its time.

Farsi-dial Omega Cosmics are a recognized category among collectors, yet they were not bespoke commissions. Instead, they originated from a very limited production run intended for the Middle Eastern market. A closer look at the dial reveals an important distinction: rather than the Eastern Arabic numerals commonly seen today, the script is true Farsi, identifiable by the heart-shaped numeral five.

Most of these watches were originally delivered to Iran. It is widely believed that the majority were sold in Tehran, then a rapidly modernizing, oil-wealthy capital under the rule of Mohammad Reza Pahlavi.

The Omega Cosmic calendar was produced in five round-case references, offered in both 35mm (Refs. 2606, 2471, and 2473) and larger 37mm formats (Refs. 2485 and 2486). Farsi-signed dials are most frequently encountered in the 2606 and 2486 references. The present example features a “jumbo” 37.5mm pink gold-plated case—an era-specific detail that highlights Omega’s broad material offerings at the time, which ranged from stainless steel to gold-plated and solid gold constructions.

The pink gold-plated case is in lovely condition and features a snap-back case back, side correctors for the moon phase and calendar functions, elegant lugs, and a thin bezel, allowing the dial to appear even larger on the wrist. The black dial shows some honest age, yet remains highly attractive and sympathetic for a watch dating to the late 1940s. It features the aforementioned Farsi numerals, with matching Farsi calendar displays visible through the dial apertures. Additional details include leaf-shaped hands, a blued hand for the date indication, a small running seconds at six o’clock, and a beautifully rendered moonphase in the same area.

We have paired this Omega with a fine Bulang & Sons leather strap.

The watch is powered by the manually wound Cal. 381, based on a Lemania ébauche, and has been fully serviced by our watchmaker.
