This is a very good example, which has had single family ownership and remains all original. It was purchased near RNAS Culdrose, a Royal Navy airbase on the Lizard in Cornwall.
 
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.
 
The Revue 57 was the second most available ATP issue watch. The dials are unsigned, unlike other ATP watches. It was a small case size at 33mm, coming with either a thick crown or a waisted crown. The case backs have a castellated design which is well constructed. The examples were mostly chrome plated cases, with full Stainless cases being less common. This is a full stainless example, with the left-hand lug stamped with an “S”.
 
A touch that makes the Revue 57 so appealing is the distinctive font of the Arabic numerals. They have a flat top 3, with tagged 1’s and are much more stylised overall. 
 
The Chrome examples tended to be earlier, whilst the Stainless examples had higher serial numbers such as this.
 
The watch is presented on a period Bonklip bracelet with the patent 349657, for 14mm lug width. This was placed on the watch by the previous original owner. The watch will have been supplied on an AF0210 Canvas strap originally.
 
This example is all original, with a handsome tropicalised patina to the dial. It also maintains its original movement spacer. A real collectors piece and a piece of military history.
