Product Description

The Story

The Omega Seamaster Aqua Terra 150M Annual Calendar is a rare and discontinued masterpiece that perfectly balances technical sophistication with maritime elegance. Featuring the iconic black "Teak Concept" dial—inspired by the wooden decks of luxury sailboats—this 38.5mm reference offers a more refined and versatile silhouette than its larger counterparts. As a discontinued model, it has become a highly sought-after piece for collectors who appreciate Omega's ability to blend a sports-watch DNA with high-complication watchmaking.

The Craft

At the heart of this timepiece is the Omega Co-Axial Calibre 8601, a self-winding movement featuring an Annual Calendar complication that automatically recognizes months with 30 and 31 days, requiring adjustment only once a year (at the end of February). Visible through the sapphire exhibition caseback, the movement boasts Omega’s signature luxury finish and a 55-hour power reserve. With its 150 meters of water resistance and classic month-date display at 3 o'clock, it is as practical as it is prestigious.

Condition & Set

This 2020 example is presented in Excellent condition, showing only light, honest signs of wear consistent with careful occasional use. It is offered as a Complete Full Set, including the original Omega inner and outer presentation boxes, the 2020 dated warranty card, and all instructional manuals. For the discerning collector seeking a "discontinued" classic with one of the most useful complications in horology, this Aqua Terra represents an exceptional opportunity.
