Movement and Mechanics

The timepiece is powered by the Omega Calibre 861 movement, which the source notes was introduced in late 1968. This manual-wind caliber utilizes a cam-actuated system for chronograph operations and is designed for high-vibration environments. The movement components, including the plates, feature a copper-toned finish. The movement is presented in a cleaned condition within the stainless steel case. The calibre 861 replaced the earlier 321 movement, intended to offer increased durability and a higher beat rate for the chronograph function while maintaining the manual-wind operation ritual.

Case Back and Provenance

The stainless steel case back features an embossed Hippocampus emblem. The metal surface is engraved with the text "F.H.P. JUNE 1970," which serves as a chronological record of the watch's initial presentation. The auction description maintains that the case remains in an unpolished condition, with the geometric lines of the lugs and case body appearing sharp.

Dial and Bezel Configuration

The watch is fitted with a stepped dial, a design feature where the outer minute track resides on a lower plane than the central dial surface. This configuration creates a three-dimensional appearance that the vendor reports was discontinued shortly after this reference production run. The hour markers retain their original tritium luminous material, which has aged to a custard-toned patina. The bezel insert is identified as an original Dot Over Ninety (DON) example. While the auction description reports that many such inserts were replaced during historical maintenance, this specific piece remains with the watch. It shows minor paint loss on the outer edge, positioned between the five and six o'clock markers, described by the vendor as a minor wear mark.
