The previous owner purchased this watch in 2008 and had it overhauled with Omega's complete service in November 2020. At that time, missing bracelet links were also added. It was used with care, but there are minor scratches. Case diameter: 36mm (excluding the crown). It's a design that's not too large and won't get old. This is the first series of the Aqua Terra. Discontinued and rare. Selling due to a replacement purchase. Please check the serial number in the images. If you wish, I can include the service receipt, but personal information will be redacted. The outer box and storage case show signs of aging. Due to the high value of this item, returns are not accepted, considering the risk of substitution. Thank you for your understanding.
