This sale is for a Onsa Airvac 6000 Compressor Automatic Watch  .
Brand new old stock from early 1970s . Swiss made with 21 jewel Tissot Cal 2481 movement .
 
Compressor watches are very collectable . Designed using a particular style case that makes them more water proof the deeper they go due to pressure on the back cover . I can't guarantee this is waterproof though due to age . Please check the following link .
