Worn
Forty millimetres, nine point six tall.
The case sits low because the calibre is thin, and it is thin because the house makes one calibre and has had the years to take material out of it. The lugs turn down early, so the strap leaves the case close to the wrist.
On a navy cuff the Fathom is the darkest thing in the room until the light finds the dial, and then it is the brightest.
The blue
Deep water, brushed.
The blue is not a paint. It is a galvanic layer over brass, brushed from the centre outward in one pass, then lacquered clear. Under a lamp the brushing throws a single spoke of light that turns with the wrist; in shade the dial goes to the colour of water at forty metres. The house wears this one.
Model view
