Pre-owned Omega Seamaster Aqua Terra 150M ref 220.10.41.21.01.001.  Omega rang in the collection’s 15th anniversary in 2017 with a design rehaul that included swapping the original vertical teak concept dial with a horizontal motif.  Additionally, the date moved from 3 o’clock to 6 o’clock.  These changes make it easy to spot a modern Omega, as seen on the Aqua Terra for sale here.  This model is a stainless steel watch in 41mm.  The case is rated waterproof up to 150 meters and wears on a matching three-link bracelet with polished and brushed links.  The watch also features striking rhodium-plated hands filled with Super-LumiNova and the caliber 8900 self-winding mechanical movement with a Co-Axial escapement and a 60-hour power reserve.
