Omega Seamaster Automatic Ref. 566.0033 - Circa 1970 | Calibre 684
Red minute markers line the white outer ring of this compact Seamaster. Raised metal indices, extending onto this ring, add depth to the dial with their polished edges and dark centers. Sized as a women’s watch, this Omega combines a detailed, sporty dial with a 24-jewel automatic movement.

The silver-toned center features a subtle radial texture that shifts in shade depending on the angle of the light. The white minute ring stands out distinctly from this surface, while the red markers remain eye-catching despite their small scale. A double index at the 12 o’clock position provides orientation, and the dark-colored hour and minute hands finished with light-colored tips harmonize with the metal indices. The raised frame around the date window at 3 o’clock further complements the dial’s layered construction.
With a movement serial number of 32,509,068, the watch dates to approximately 1970. The case design, characteristic of the era, is defined by expansive stainless steel surfaces surrounding the round dial. A brushed top section, a polished bezel, and beveled edges catch the light from various angles. The sharp geometry of the short lugs contrasts with the softer, flowing contours of the case. A slightly domed acrylic crystal enhances the watch’s vintage character, especially when viewed from the side.
Housed within the case is the 24-jewel Omega Calibre 684 automatic movement. Operating at 21,600 semi-oscillations per hour, this Swiss caliber offers a power reserve of approximately 45 hours, along with a central seconds hand and a date display. The movement which can be wound either by the motion of the wrist or manually via the crown dates from an era when Omega was developing compact automatic calibers. Upon opening the case back, one finds copper-toned bridges, ruby-colored jewel bearings, and a semi-circular rotor.
The outer side of the screw-down case back features the embossed Hippocampus (seahorse) emblem of the Omega Seamaster. The inner side bears the reference numbers 566.0033 and 566.0039. The "CB" stamp identifies the Swiss manufacturer La Centrale Boîtes, which produced cases for Omega.
The watch comes on a custom-made black calfskin strap. The strap’s subtle cross-hatch texture creates an appealing contrast with the brushed steel case, while its black hue highlights the dark details on the dial. Both the crown and the steel buckle feature the Omega emblem.
Final Thoughts
On this Seamaster, the eye is immediately drawn to the red minute markers and the raised, applied indices. Beneath the case back, the movement compactly engineered houses a rotor, a calendar mechanism, and jewel bearings. What makes this timepiece so compelling is that the richness of detail found on the dial continues within the movement itself.
