Patek Philippe, Ref. 3970 and Ref. 3971
 
This reference is launched in 1986.
 
The production of this model began with the Cal. 27-70 Q bearing the serial number 875 000.
 
When Patek Philippe first launched this new series of watches, Ref. 3970 was the model bearing a metallic snap-on case-back, while Ref. 3971 was equipped with a screwed down sapphire case-back.
 
Very soon, the reference number of this model was standardised to Ref. 3970, sold either with one or two screwed down case-backs; one of these backs could be a screwed down metallic case-back, while the second, (non-compulsory), a screwed sapphire crystal case-back.
 
In consequence, very few watches bear Ref. 3971.
