Very rare and attractive steel Favre-Leuba Bathy ref. 160, manufactured in 1970’s.
In the late of 60’s, the great success of the Bivouac inspired Favre-Leuba to employ the principle of the aneroid barometer to pressure measurement underwater as well: In 1968, the brand introduced the Bathy, the world’s first mechanical wristwatch that displayed not only dive time, but also the current depth.
Two models were introduced, one measuring the depth in meters and the other in feet. The present specimen measured the depth in feet, up to 160 ft.
Dive time could be adjusted and monitored using the rotating bezel with 60-minute graduations and the minute hand. A diaphragm inside the case transmits the pressure changes underwater to the black hand of the depth gauge, which indicates depths up to 160 ft on the outer dial scale.
On ascent, a red scale on the dial supported the diver in keeping within the necessary decompression times. The numbers and hands of the Bathy had an extra-high luminosity, so that they were easy to read without error even in poor visibility conditions.
The present example stands out for its amazing appeal.
The dial has naturally aged in a wonderful multi-graduation of orange and yellow tones. It features the “Aqualung US Divers” symbol, a black decompression stages indicator hand and a large minutes hand with a subsidiary sector seconds.
The orange bi-directional rotating bezel enhances the charme of the whole time piece.
