All Original down to the acyrlic crystal. The original GP bracelet made by J.B Champion has more heft to it than my previous 1016 Explorers. 


Has a rare spanish day of the week wheel and date. The blue dial is in all original condition and is made by Signer during the same time they produced newmans.


Signed crown , brushed case finishing parts in tact , never been polished , earliest High Frequency Gyromatics with the 17 jewel movement and nice rhodium plating with burst angulage and perliage around the balance.


The bracelet springs are still strong hence the bracelet is suprisingly not too loose.


With outer race track minutes , blue dial , and original bracelet this is straight from the vintage nautilus era of the 70's but probably little cooler.
