PLEASE CHECK OUT MY OTHER LISTINGS FOR MANY SIMILAR WATCHES BEING LISTED.  During the week of April 29th, I will be listing about 30 quality watches, most of which are automatic chronographs (mostly ETA/Valjoux 7750 models) including brands such as Corum, Invicta (auto chronos and meteorite models), Aragon, Android, Philip Watch, Jacques Lemans, Ernst Benz, Georg Jensen, and Certina.

This listing is for an Ernst Benz GC40114 Chronoscope mens automatic chronograph.  Case reference 40100.   Blue dial.  Stainless steel case.  44 mm case width, 48 mm with the crown.  Large, heavy watch watch, but not a gigantic oversized timepiece.
Watch is powered by the ever popular and reliable Valjoux 7750 movement.
Working perfectly and keeping great time.  All chronograph functions work as they should.  Automatic winding working as it should.
The strap is a new stitched leather aftermarket replacement with the original Ernst Benz buckle. 
Excellent condition with just some very light "desk diving" scuffs, probably not even worth mentioning.
The watch has Super LumiNova lume on the hour markers and hour and minute hands.  I had the watch on a table in a moderately lit room today (not in direct sunlight), for a few hours today...then went into a pitch dark room and I can see the number markers and hands quite well and could read the time quite easily.  
No boxes or paperwork, just the watch.  
I believe this watch will qualify for ebay's third party authentication, in which case it will first be shipped to a third party authenticator designated by ebay.  There, it will be authenticated and shipped to you with some paperwork detailing the authentication.  This is at no cost to you.
