The idea: time at the collar
With a tuxedo or tailcoat, a wristwatch often feels out of place, and a bow tie is purely decorative. The Bow-Watch-Tie unites both: a genuine Swiss watch sits at the centre of the bow tie, held by a gold-plated mounting plate.
The most classic accessory of evening wear becomes a functional timepiece – discreet, elegant and unmistakable.
The inventors
The Bow-Watch-Tie was invented by Markus, David and Kyrollos Istafanous, the people behind the Zircon Swiss brand and Black Pearl Zircon SA in Biel/Bienne. Learn more about them on our team page.
