The Beautiful Watch opinion
WOW!!! This military, British Navy, single-pusher chronograph from the '40s has a sublime patina!!!
This chronos were ordered by the Royal Navy in the 1940's until the late 1960's (with a few different iterations).
The "Broad Arrow" indicates that it was indeed a Royal Navy watch, and more specifically belonged to the "Hydrographice Service", which was in charge of mapping harbours and waterways from the 1940's, and the number 9 indicates it's a chromometer, hence the HS9.
This one was reissued for NATO as the HS9 at the back is double crossed, and the NATO storage number engraved above (0552/924-3305). This indicates the watch was made between 1945 and 1950, though more likely towards the end of the 1940's as earlier versions were not signed on the dial. This one was actually relumed in the 60's as testifies added the circled T (for Tritium). However, this only indicates the watch was in service for quite some time, as per regulations on radioactivity in the 1960's meant dials had to be relumed to meet those new requirements.
Inside is the superb manual winding Lemania 15CHT, that still runs like a charm today.
In short, this is an exceptional watch with a great history, stunning, with an indestructible movement, a piece to have in one's collection, undeniably!
