I have a question with this Armys , it is one of the few " Oyster " configuration en link 560 ( 19 mm ) 1168 (15mm ) . With eslabon solid and type " Oyster " , __Omega De Ville with the 930 caliber. Clock I have no doubt , I spend a review on Omega, but the Armys have some doubts , it will be an odd or an aftermarket OEM part . Excuse my bad English , translate use.
