kirkdj,
There was no specific model name from that decade in Piaget history. Descriptive words would have stated the gender, materials used viz. gold, diamonds (carat, cut, colour, clarity), metalwork pattern and watch size.
This item is currently valued as scrap material because without restoration, it is neither a complete watch nor jewelry.
The watch does not work.
The watch-glass is missing.
The dial is damaged.
The gem stones are loose and the settings damaged.
CONCERNS
One concern is your description as 14K gold because Piaget does not usually make 'high jewelry watch' with 14K gold.
Piaget is also known for the baton hour markings on their dials rather than dots.
See other examples of Piaget Secret Watches for finger and wrist but in 18K gold.....

MTF
