IWC Ingenieur Perpetual Calendar 41 (Ref. IW344904)

A monolithic design, yet the lightest-ever Perpetual Calendar within the IWC collection. The new Ingenieur Perpetual Calendar 41 unites a signature IWC material – grade 5 titanium – with our most emblematic complication. The case, bezel, and bracelet links showcase a combination of sandblasting, polishing, and satin-finishing. The matte grey dial boasts the characteristic "Grid" structure, while the subdials displaying the calendar information are treated with a circular satin finish, adding visual depth. Ref.
