50th Anniversary ad





















Originally built by Gruen to commemorate their 50th Anniversary 1874-1924. This very special watch originally retailed for $500 way back in 1924!! (see the original 1924 ad above. These Solid Platinum first issue Gruen Pentagon 50th Anniversary watches are now retailing from $15,000-$20,000!!)



The Pentagon case design was Patented & Copyrighted by Gruen. Only 600 were made, (one for each month that the Gruen Company had been in existence) 



Very -Very few people could ever afford the 1924 $500 purchase price. However, due to the overwhelming desire to own one of these rare Pentagon Anniversary watches, a limited number were built in metals other than Platinum using the original patented and copyrighted case dyes.
