The perpetual calendar chronograph wristwatch, reference 3970, was released from 1986 to 2006. It was cased in platinum, white gold, pink gold and yellow gold. There are three series in which reference 3970 was produced: the first series featured a snap back case. The second series featured a solid case back, and was produced concurrently with reference 3971 with a snap sapphire case back. The third series, like this example, was accompanied with “E” for “étanche” or waterproof. 3970 Was the first reference to use a lemania 2310 based movement, not a Valjoux movement. The present watch is in good overall condition, with a crisp hallmark under the lugs and a Patek Philippe extract of archives newly issued.
