This is a Vintage Iaxa Chronograph from the 1970's with the famous Valjoux 7733 movement.  It's gold plated and the case is stylistically like the Patek Nautilas.  The deep blue dial is still colourful and has gold batons around the edge.  Fully working Chronograph and Tachy dial on the outer edge of the dial means it's a fully functioning sports watch that looks stunning in gold.

The case looks amazing and is gold plated.

The blue mesh steel strap was added to set off the blue dial.  It also looks great with a black Nato strap.

Very rare watch and very collectable. Runs well with an automatic movement that delivers a long running time.
