Favre-Leuba Bathy V2
[ via Favre-Leuba ]
Here is the official release from the re-launched Favre-Leuba.
More than 40 years after its revolutionary impact on the world of diver's watches, the legendary Bathy is making a major comeback in an automatic version! Its innovative depth gauge works on a beryllium copper membrane which contracts under the pressure of the water entering the double back. The deviation is less than 0.18%! Such precision - pushed to its limits in the most extreme conditions - is one of the hallmarks of Favre-Leuba, a company that has been making watches for almost 300 years.
