Omega Seamaster Aqua Terra
Reference 231.10.39.21.06.001 · 2023
Up for sale is my Omega Seamaster Aqua Terra ref. 231.10.39.21.06.001, featuring the highly desirable gray teak dial and the first-generation in-house Co-Axial Caliber 8500. This reference represents one of the best Aqua Terra generations ever produced. The 38.5mm case offers near-perfect proportions, wearing comfortably on a wide range of wrist sizes while maintaining the versatility that made the Aqua Terra such a popular everyday luxury watch. The vertically brushed gray teak dial is inspired by the wooden decks of luxury sailboats and changes beautifully under different lighting conditions, ranging from warm gray to rich charcoal tones. Powering the watch is Omega's in-house Co-Axial Caliber 8500, featuring a twin-barrel architecture, free-sprung balance, and Omega's signature arabesque Geneva waves visible through the sapphire display caseback. The movement offers a 60-hour power reserve and remains one of Omega's most respected modern calibers. The watch is in excellent overall condition and was serviced on June 2026. The case retains strong lines with only light signs of careful wear. Bracelet Size: Sized for an 18.5 cm (approx. 7.25 inches) wrist. Please note: No extra links are included. The watch comes with its original presentation box and papers. Please note that while the box is structurally sound, the exterior red faux-leather coating is flaking and peeling, which is very common for Omega boxes from this era. The watch itself is unaffected.
