Omega Seamaster Aqua Terra 150m Co-axial Master Chronometer 220.13.41.21.01.001

The Omega Seamaster Aqua Terra 150m Co‑Axial Master Chronometer ref. 220.13.41.21.01.001 is a true do‑it‑all modern Omega—mixing maritime Seamaster heritage with dress‑leaning elegance thanks to its black teak‑pattern dial and alligator leather strap. This pre‑owned example comes as a complete set with inner/outer box, operating instructions, and full card suite, giving collectors a well‑equipped, current‑generation Master Chronometer in a highly versatile configuration.


Condition: Pre‑owned; please review photos for specific signs of wear.
Set & Documentation: Watch with original Omega inner and outer box, operating instructions booklet, and red warranty / pictogram / Master Chronometer cards.


The watch features a 41 mm stainless steel case with a symmetrical profile, sapphire crystal front and back, 150 m water resistance, and a thickness of around 13.2 mm, making it slim enough for cuffs yet robust for light sport and travel. Its sun‑brushed black dial carries the horizontal “teak” pattern inspired by yacht decks, applied arrowhead indexes, date window at 6 o’clock, and luminous hands/markers for excellent legibility day or night.


Powering the watch is Omega’s in‑house calibre 8900, a METAS‑certified Master Chronometer movement with Co‑Axial escapement, 60‑hour power reserve, time‑zone jumping hour hand, and resistance to magnetic fields over 15,000 gauss—all visible through the sapphire caseback with Geneva waves in arabesque. It is paired with a black alligator leather strap and steel folding clasp, giving the watch a refined, slightly dressy character that still feels at home in the Seamaster line.
