About watch movements The Luminor Marina (PAM00113) is equipped with the OP XI movement based on the ETA 6497. This movement was a masterpiece adopted by Unitas, which was later absorbed by ETA. When Panerai made its official global debut in 1997, this ETA 6497 (or 6498) based movement was chosen as the flagship movement. Watch enthusiasts affectionately refer to it as "unitas." In the past, Panerai utilized this movement in their models. Given Panerai's current transition to in-house movements, models like the one featuring the OP XI movement based on ETA 6497 are considered valuable among collectors.
