IWC Schaffhausen Spitfire Perpetual Calendar Digital Date-Month (Ref. IW379107) Steel Version

First introduced in 2012 with an 18-carat red gold case, the Spitfire Perpetual Calendar Digital Date-Month (Ref. IW379107) from IWC Schaffhausen is now also available in a stainless steel case. The Spitfire Perpetual Calendar Digital Date-Month combines tasteful design with the art of watchmaking at its finest. It is the only IWC Pilot’s Watch to show the date and month digitally in the form of four large numerals.

In visual terms, it goes perfectly with the instrument appearance and revives the tradition of the Pallweber system, now dating back well over 100 years. The sapphire-glass back invites you to take a look at the movement with its unusual rotor in the delicate shape of a Spitfire silhouette.
