This is a Hamilton Mark XI watch made for the RAF. Black dial with Broad Arrow mark and T within a circle, denoting the use of Tritium (luminous) on the dial and hands. 36mm diameter. This is an early non-hack variant, anti-magnetic known as a British R.A.F. Hamilton “6B” or “The Hamilton Mark 11”. We have fully serviced and regulated the movement. The watch runs very well and keeps excellent time.
