During its reign, the 3970 underwent three major transformations. The first generation were fitted with a snap solid back, the second with a sapphire crystal case back, named 3971. Patek Philippe finally created the third generation, 3970E, where étanche meant waterproof. The present example, 3970E, presented as a full set with original certificate, additional case back, setting pin and product literature, is among the later examples manufactured by Patek Philippe. The watch is fitted with a rare and attractive diamond-set black dial. The watch is in extremely well preserved condition with sharp hallmarks to the side of the lugs. The lugs themselves with very good proportions and very good fluting.
