Hi Fabrizio, my reference number is 3511.50 with cal 1152. This is a Self-winding chronograph with hour, minute and small seconds hand, central chronograph hand, 12-hour and 30-minute totalizers, start/stop push button , return-to-zero push button. I was wondering where I can obtain the operating instruction for this. Thx.
