Unworn, Omega Seamaster Aqua Terra 150M, Ref# 220.15.30.20.56.001, box and papers.

The OMEGA Seamaster Aqua Terra 150M Ref. 220.15.30.20.56.001 is an elegant ladies' timepiece that perfectly blends refined luxury with OMEGA's latest achievements in Swiss mechanical watchmaking. Inspired by the brand's rich maritime heritage, this sophisticated 30 mm model is crafted from polished stainless steel and enhanced by a dazzling bezel set with 46 brilliant-cut diamonds, adding exceptional brilliance to its timeless design. The grey PVD-treated sun-brushed dial is finished with a glossy lacquer coating and features eleven diamond hour markers set in 18K white gold holders. Redesigned faceted 18K white gold hands, filled with white Super-LumiNova®, provide outstanding legibility while emitting a blue glow in low-light conditions. A circular date aperture at 6 o'clock maintains the dial's elegant symmetry, while the domed scratch-resistant sapphire crystal with anti-reflective treatment on both sides ensures remarkable clarity and durability. At the heart of the watch beats the OMEGA Co-Axial Master Chronometer Calibre 8750, a self-winding movement certified by METAS for exceptional precision, performance, and resistance to magnetic fields up to 15,000 gauss. Equipped with a Co-Axial escapement, silicon balance spring, and automatic winding in both directions, the movement delivers a reliable 48-hour power reserve. Through the sapphire exhibition caseback, the beautifully finished rhodium-plated movement with Geneva waves in arabesque can be admired. Completing the watch is an integrated stainless steel bracelet with polished and brushed links, secured by OMEGA's butterfly clasp with a patented comfort-adjustment system. Water-resistant to 150 meters.
