Stunning J. W. Benson London One Button Chronograph Oversize 37mm Watch

Stunning circa 1915-1920 J. W. Benson, London man's oversized one button chronograph wristwatch in excellent condition. It should be noted that this is an original wristwatch, and NOT a pocket watch that has been later converted. The .900 silver wire lug case shows light signs of use, excellent condition overall. Excellent original porcelain dial with lume that has achieved a nice orange patina to the hands and markers (some lume missing in hands as shown). Excellent crystal and crown. Inside, the hand winding movement is running strong and keeping excellent time although service history is unknown.  All chronograph functions work as intended.  Fitted to a gently used leather strap with steel buckle. Case measures 37mm wide with 13mm lugs. Authenticity unconditionally guaranteed.
