Housed in a round 39mm stainless steel case with a brushed and polished finish, this Omega Aqua Terra Annual Calendar measures 14.7mm in thickness and features a fixed bezel, a screw-in crown, and a transparent case back that offers a view of the automatic movement within. The silver dial presents the annual calendar complication clearly, while an anti-reflective scratch-resistant sapphire crystal ensures an unobstructed read in virtually any light.
Water resistance is rated to 150 metres / 500 feet, supported by the screw-in crown for a reliable seal. The watch is secured to the wrist by a stainless steel bracelet fastened with a push-button folding clasp, keeping the case material consistent throughout.
Reference 231.10.39.22.02.001 is driven by an automatic movement, making it a compelling choice for those seeking a calendar function that requires only a single correction per year — at the turn of every month with fewer than 31 days.
