IWC worked to keep momentum through the quartz era. Though they produced some models with quartz movements, they kept their focus on the brand's watchmaking traditions. The brand introduced the classic Portofino collection in 1984, adding a quintessential dress watch to their offerings. During this decade, they also began experimenting with new materials. IWC created the first watch case constructed from titanium in 1980. Six years later, they employed a scratch-resistant and virtually unbreakable ceramic called zirconium oxide as a new case material.
In 1993, IWC celebrated its monumental 125th anniversary. To commemorate the occasion, the brand debuted the most complicated mechanical wristwatch to date as well as a special edition of the popular Portuguese. They produced the II Destriero Scafusia in a limited edition of just 125 pieces. The model boasted an impressive set of complications, including a tourbillon, split-seconds, minute repeater, and perpetual calendar. A year later, they extended their legendary Mark collection with the Pilot's Watch Mark XII.
At the turn of the century, IWC became part of the illustrious Richemont Group. With a new network and set of resources, IWC was able to revisit the production of past collections and continue to expand on their current offerings. By 2002, the brand had revived the beloved Big Pilot's watch at the annual SIHH exhibition. In 2004, they relaunched the Aquatimer collection, and in 2005, the Ingeniuer made a comeback. Then, in 2007, IWC secured a meaningful partnership with the advanced fighter weapons school, Top Gun. For the first time, the prestigious organization allowed the "Top Gun" name to be associated with a watch brand, and the IWC Top Gun was born.
2008 marked the 140th anniversary of IWC. This time, the brand launched an exclusive IWC Vintage Collection to honor the milestone. Then in 2015, the brand celebrated the 75th anniversary of the Portuguese with an all-new variation of the model. The models housed IWC's newly designed 52000-calibre and boast annual calendar and digital calendar complications.
Today, IWC continues to embody its founder's spirit of innovation. In 2018, they unveiled a state-of-the-art online customization tool for the Ingenieur Chronograph. The launch marked the brand's first foray into built-to-order watches.
