Though not a sector dial , very much like a sector dial there is a lot of play. First the gilt chapter ring , to truly see it in glory you must look at it in sunlight. Then there is a two tone black dial. The outer dial is glossy black , while the inner is matte. All while the outer dial hour numerals and hands are in radium that still shine for a second.  Very nice spade seconds hand and gilt 24 hour numerals. Oversize original crown.
 
	
34mm without crown.
 
	
All original dial and hands ,  some radium has cracked off the minutes hand.
 
	
Manual wound movement , keeping decent time.
 
	
On a new , French oily calf leather strap.
