The screw-down case back was a new approach at the time, which has now become the standard. Longines first used it for its chronographs, then for its three-hand watches.\u003c\/p\u003e\n\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #ddd; padding: 10px 0;\"\u003e\n\u003csummary style=\"cursor: pointer; font-weight: 600;\"\u003eThe 12.68Z calibre in brief\u003c\/summary\u003e\n\u003cp\u003eIt is a Longines manual-winding calibre, with 17 jewels and shock protection.
