Seiko Silver Dial "Lordmatic" 5606-70 Gentleman's Automatic Winding Watch

From the serial number on the case back we can accurately date this watch to being made in May 1968.  
This Lord Matic has a unibloc, one piece case that means the movement has to be removed from the front.  This not only improves water resistance, but also stops anyone not experienced with tampering with the movement – you need the knowledge to remove the movement with this design.  This is the more popular Day/Date version of the 56 movements, and the quick set date is working correctly.  The silver dial , and hands are perfect.  The bracelet is comfortable on my 7.5" wrist.  The bracelet has been cleaned 
 The entire watch is in pristine condition, working perfectly.
