Moeris ATP watches are the most encountered of the lot, but that isn’t to say that they aren’t also popular choices. They are the largest of all the ATP watches at 33mm and they have an impressively bold dial, with thicker radium markers than others. This example has the correct case back, with a serial number in the 6xxxx range. 
 
ATP watches:
ATP stands for ‘Army Trade Pattern,’ which set the rules of design to create these watches for British armed force. They were introduced in 1939 and saw significant use in the field, whereas the more desirable WWW watches only played a part towards the tail end of the war. The ATP watches proved so popular that they remained in service until 1957, often with new engravings to the rear for their new purposes.
 
In total, 17 Swiss manufacturers provided ATP watches for the British, all with subtle differences, but broadly of the following specification. 
 
They needed to be roughly 30-34mm in size, with a white or silver dial and black numerals for legibility, and a sub-second register for precision. The cases had fixed bar lugs to ensure no spring bar failures. They featured reliable movements with 15 jewel movements or higher and were manual wound. To further aid legibility at night, the hands were to have luminous lume, along with the hour markers.
