movement date symbol means this is either 1925 or 1934 I've gone for the latter but it's a guess, case serial number begins with a 9 so don't know if it's a replacement movement. I don't like adding a pic ang saying please work it out for me but I'm lost with watches of this age so I'm leaving it to you guys sorry. Please note magic hour hand is BST ;)

Case Serial No.
