Mid size version of the electric blue 2055.80 SMP, known as the 2053.80. You will see many more serch hits for 2255.80 and 2253.80 but yours has the Bond bracelet so has a different number to the latter 2 I mention which have the Speedy type bracelet. If you get it serviced at Omega, they will replace the second hand with a new one with a bright red tip and also republish the case as part of a full service.
