The Portugieser Yacht Club Chronograph was introduced in 2015. It features a case that is slightly smaller than the previous Yacht Club models, from 45.4 to 43.5 millimeters. It is powered by the IWC-manufactured 89361 calibre with 68 hour power reserve. It features a small seconds display at 6 o’clock. Reference IW3905-07 was added to the collection in 2018 as part of a new ‘Summer Editions’ collection. It features a blue dial with silver subdials and a blue rubber strap.
