This is a great looking watch that improved with the addition of a modern rubber blue strap.  It matches the dark blue dial perfectly and compliments the Pepso bezel.  Pepsi bezels are becoming very popular and collectable.  This is a great example of a Pepsi with the oval oversized case and 24 hour inner markings.

The Green batons on Mortima watches are simple but effective and they make for a well designed dial.  The movement works well and runs on time.  In good condition with only slight wear on the back side from being on a wrist for 40 years.  Like most Divers watchs of this period it is Incabloc shockresistant and antimagentic.
