🔎 CASE NOTES

The Aqua Terra has always occupied the middle ground between Omega's professional sports watches and its more formal offerings, but the Small Seconds version adds considerably more visual character to that formula. Reference 220.10.41.21.02.004 pairs a silvery-grey horizontally "teaked" dial with blue hands and hour markers, while relocating the running seconds to a subdial at 6 o'clock.

That subdial is particularly well executed. Omega integrates the date display directly into the small-seconds register, preserving the symmetry of the dial while giving the watch a complication rarely seen within the standard Aqua Terra family. Depending on the light, the dial can move from nearly white to distinctly silver-grey, with the blue furniture providing the contrast.

Inside is Omega's Co-Axial Master Chronometer Calibre 8916, a METAS-certified automatic movement offering approximately 60 hours of power reserve and Omega's formidable resistance to magnetic fields reaching 15,000 gauss.

Case #608 dates from 2025, remains within Omega's five-year factory warranty period, and is presented in very good pre-owned condition with box, papers, and cards. The bracelet is currently sized for approximately a 7.25-inch wrist.

Omega confirms the 41mm case, Calibre 8916, sapphire crystal and 150m water resistance for this exact reference.

Condition Notes: Very good pre-owned condition with signs of previous ownership consistent with careful use.

🔵 THE SMALL-SECONDS DIAL

This is where the reference separates itself from the conventional Aqua Terra.

Moving the seconds hand away from the center creates an entirely different visual rhythm, while the integrated date at six keeps the dial balanced. The blue hands and indices against the silver-grey teak surface add considerably more color than the specification sheet suggests—the dial can appear almost white under artificial lighting before revealing its silver tones in natural light.

It's unmistakably an Aqua Terra, but not one you're likely to mistake for the standard center-seconds model.

⚙️ MASTER CHRONOMETER ENGINEERING

The Calibre 8916 gives the watch serious technical credentials underneath its relatively restrained exterior. It is a Co-Axial Master Chronometer movement with approximately 60 hours of power reserve, displayed through the sapphire exhibition caseback.

Combined with 150 meters of water resistance, the Aqua Terra remains one of Omega's most versatile propositions: refined enough for formal wear but engineered with specifications that allow it to function as a genuine everyday sports watch.

🌟 COLLECTOR PROVENANCE

The Small Seconds occupies a less commonly encountered branch of the Aqua Terra family. The unusual dial architecture, blue accents and Calibre 8916 give it a distinct identity without abandoning the fundamental design that makes the Aqua Terra so versatile.

This particular example adds two significant advantages: 2025 dating and remaining Omega factory warranty. Combined with its complete BPC presentation and very good condition, Case #608 offers much of the appeal of a current example without starting again at retail.
