I found this gem in Switzerland... maybe this is the first time it has been out of the country? It is a Rodana Landeron 48 based chronograph.
Rodana is a Swiss encaser founded in the 1930s. At one point they changed their name to Rodania 'due to legal reasons' according to one web entry. The company still exists and still has an active market in Canada and western Europe.
This is a chronograph which the seller claimed was from the 1940s. There is no way to confirm the date. Landeron 48s were made from 1937 to 1970. The dial, while in fairly good shape, looks old enough. But the back may have been replaced. If it hasn't been replaced, the watch has lead a fairly quiet life. The lack of shock protection does lend credence to a 1940s date for the watch as a whole.
I loved it's look and the price was an amazing steal... well less than 200 euros. So I had to get it. It works. I haven't timed it yet but it looks good so far.
We'll see if it looks like it needs service after I get it on the timing machine. I hope not as no one will COA an old chronograph for the same price as a 17 jeweled winder! And my watchmaker says parts will be "difficult". Service will double it's price...
