Seamaster Aqua Terra 150M Co-Axial Master Chronometer 34

The Omega Seamaster Aqua Terra 150M in 34 mm offers the full technical pedigree of the Aqua Terra line in a more compact stainless steel case. Powered by the Calibre 8800, it carries Master Chronometer certification — the highest standard jointly defined by Omega and METAS — and pairs that precision with a distinctive blue wave-pattern dial. The 34 mm sizing makes it one of the more versatile expressions within the Seamaster family.

The Aqua Terra line has long served as Omega's bridge between the Seamaster's maritime heritage and everyday elegance, and the 34 mm case size reflects a sustained collector interest in mid-size and traditionally proportioned watches. Reference 220.10.34.20.03.001 entered production in 2022, bringing the Co-Axial Master Chronometer movement architecture — previously reserved for larger references — into this smaller format. The result is a watch that sits comfortably within the modern Aqua Terra family while appealing to collectors who prefer a restrained case diameter.
