Pre-owned Omega Seamaster Diver 300M ref 131.12.41.21.06.001 (2021). The Constellation is defined by a few key elements: the “Griffes” or claws on the case, the integrated feel, and the Roman numeral bezel, and all of that is still front and center here. This version comes in a 41mm stainless steel case, giving it a much more contemporary presence compared to earlier models. The rhodium-grey dial has a subtle, silk-like texture that shifts depending on the light, paired with blackened hands and markers for a bit more contrast. The Roman numerals around the bezel add structure, while the date at 6 keeps the dial balanced. It’s paired here with a black rubber strap, which gives it a sportier aesthetic than the usual bracelet versions. Lastly, inside is the Master Chronometer caliber 8900 with strong accuracy, anti-magnetic resistance, and a solid 60-hour power reserve. Shop OMEGA Seamaster Collection
