IWC recently unveiled a new rattrapante chronograph, the Ingenieur Double Chronograph Titanium. Also called a split-seconds chronograph, a rattrapante utilizes an additional central seconds hand that allows the wearer to simultaneously measure two events.
The case of the new Ingenieur is made of titanium. Titanium is light, durable and will not cause any skin allergies. The case measures 45 mm in diameter and 16 mm in thick. Black DLC coated screws secure the bezel to the case. The pushers and crown are coated in vulcanized black rubber.
Inside, is a self-winding mechanical movement, calibre 79230, with 29 jewels and a 44-hour power reserve. Solid caseback. Double anti-reflective sapphire crystal. Water-resistance is 120 meters (393 ft). (Ref. IW37653765)
