Omega Seamaster 300M Mid-Size Quartz 2561.80 - Joe Biden
US President Joe Biden wears a Omega Seamaster 300M 2561.80 Mid-Size Professional Diver Quartz watch.
The watch is the smaller version of the blue dial / blue bezel Seamaster 2541.80 Quartz watch which was the first Omega watch worn by James Bond (Pierce Brosnan) in the 1995 movie GoldenEye - read more on the Bond Lifestyle website).
The size of the 3 o'clock hour marker is one of the indicators that this is a Mid-Size (and not a full size) Omega Seamaster 300M Quartz. On the larger 2541.80, that marker is much wider than on the 2561.80 Mid-Size.
The 2561.80 Mid-Size watch has a Quartz precision movement 1538 with rhodium‑plated finish and end of battery life indicator (seconds hand will skip every 4 seconds to indicate an almost empty battery(.
The exact same model watch, also a Omega Seamaster 300M 2561.80 Mid-Size, is owned by Prince William, Duke of Cambridge.
Joe Biden owns several other interesting watches including an Omega Speedmaster (the moon watch, seen in many films), a Seiko 7T32-6M90 Chronograph and he has been spotted with a Tissot T-Touch (black dial), a watch sometimes seen in films. He also owns a Rolex Datejust, with steel case, blue dial, on a jubilee bracelet.
