The Aqua Terra 41 is Omega's workhorse sports-dress watch: polished enough for a suit, robust enough for everyday wear, and backed by the best antimagnetic movement the brand has ever put in a steel sports case. The 15,000-gauss resistance is not a marketing footnote; it solves a real problem for anyone who works near electronics or carries a phone all day. At used prices, you get a COSC-plus-certified Master Chronometer movement for less than most microbrands charge for an ETA.
Omega introduced the Aqua Terra line in 2002, and the 41mm case arrived as the size expanded through the mid-2000s. The reference 220.10.41.21.03.001 specifically marks the 2017 introduction of the Co-Axial Master Chronometer caliber 8900, which replaced the earlier 8500/8507 family and added METAS certification to the existing COSC rating. The teak vertical-stripe dial pattern is a design constant across generations, meant to evoke teak wood decking on a sailboat; the execution is subtle in person, less busy than photos suggest.
Omega has offered this case in blue, green, grey, silver, and black dials across the current generation, and both bracelet and rubber strap configurations ship from the factory at the same reference. A no-date sibling (220.10.41.21.01.001) exists for collectors who find the date wheel visually distracting at 3 o'clock.
The bracelet clasp on pre-2020 examples has a reputation for loosening over time; push the deployment open and closed several times and check that the butterfly mechanism seats firmly without play. Inspect the case middle for deep scratches around the lugs, where polishing wheels often dig in and round off the edges, which are difficult to restore properly. The 8900 movement has a transparent caseback, so tilt it in good light and look for rotor bearing wobble or debris on the dial side; the Master Chronometer certification means nothing if the movement has been opened and reassembled by an unqualified watchmaker.
Confirm the crown screws down smoothly without resistance, as cross-threading is common on examples that have been pressure-tested multiple times. Finally, ask for service history; the 8900 does not need frequent service, but a watch represented as unworn with 50,000+ power reserve cycles on the rotor is a red flag.
