Just to add to the confusion
. I actually own one of the Swiss pentagons that was posted. It has an engraving I had not researched.
The UV number is 557,438 a bit higher than the original watch posted
I looked into the golf tournament..their website shows that the tournament started in 1925 and that J.L. Bumgardner won the tourney in 1927.
It very well could be his victory watch from 1927 but since the engraving only praises the man for sportsmanship you can't know 100%http://www.virginiasseniorsgolf.com/Tournaments/History.aspx
