What are these?

The wrist watch mimics the altimeters worn by skydivers. They need to know how high they are and when it is time to open their parachutes. They should have an open parachute overhead by the time they enter the red zone (below 2,500 feet above ground level).

The various bronze and gold wings with diamonds were issued by the United States Parachute Association to recognize how many thousand jumps he made.

The "PIA" pin stands for "Parachute Industry Association" which is dominated by the companies that manufacture parachutes. Every second year (e.g. February/March 2025) they host a big Symposium that attracts hundreds of professional parachute riggers and instructors to a week-long conference in a resort city like Reno.

That white parachute with a black kite-shape hanging below it was issued by a USSR sport parachute club recognizing "X" number of jumps.
