*CAL.79240 and CAL.79350 installed in the Portugieser chronograph are basically the same and are based on the ETA Valjoux 7750.
This seems to have changed around 2007.
The appearance of the movement is gold for CAL.79240 and silver for CAL.79350.
In addition from around 2019 it has been changed to an in-house movement with a reverse side.

*Complete service (overhaul) including polishing completed at Richemont Japan (IWC) in March 2023.
At that time the needle was replaced.
*Currently it is a clean used item with few small scratches.
The case is not thin or the edges are soft and it is in good condition considering it is a used 18K gold watch.
*There are no scratches on the sapphire glass windshield.
*The genuine leather belt shows some signs of use but there are no noticeable sweat stains.

*I think this chronograph has a beautiful color harmony between the dark gray dial and WG case.
Although it is a uniquely beautiful watch the time may be a little difficult to read.
