Patek Philippe launched the 3970 and 3971 in 1986. Both references were essentially the same, however reference 3970 was fitted with a solid snap on back, whereas reference 3971 was fitted with a glazed screw back. Patek Philippe ended production of reference 3971 in 1990 and merged both references 3970 & 3971 together with the new reference 3970 offering a solid and additional sapphire crystal display back.
