The Longines Heritage Diver chronograph, a 43mm reissue of 1970s dive watches, uses calibre L651.3 to show hours, minutes, seconds, with a 60-second counter at 3, a 30-minute counter at 9, and a date at 6 on a black satin dial. A bidirectional inner flange, turned by the crown at 10 o'clock, is graded from 60 to 0 to track remaining underwater time, including decompression. It is offered on a black rubber strap.
