There are many Swiss made watches out there, and I've blogged quite a few. But there aren't many Swiss watches made this way!
The watch is called the Swiss Cheese watch. Normally, names like this mean they look like the name, but in this case, it is actually made from Swiss Cheese! More correctly, it is made from a cheese-like byproduct of milk called Casein. Casein is a protein found in the milk, and accounts for up to 80% of the protein content in cows milk. A 4000 liter batch of milk would produce 180 kg of butter and 200 kg of Casein. Some of the earliest developed plastics were made from Casein, and fibres made from this were a popular material in the 1930s. It is actually splash proof, but can't be submerged, and has a yellowy transparent appearance.
The Swiss Cheese watch is an exclusive model by RHW Eco-Time-Systems, and seems to have been developed in the late 80s or early 90s. As it's made from cheese, the tag line is "As long as there is milk, there will always be the Swiss Cheese Watch".
The watch itself is a 3-hand dial design, and has a Swiss quartz movement.
