Konstantin Chaykin Breaks the Record for World's Thinnest Mechanical Watch

For many years, the world’s leading watchmaking companies have been competing to produce the thinnest mechanical watches. Prestigious brands such as Piaget, Bulgari, and Richard Mille have been at the forefront of this race, with Bulgari securing a prominent position, dominating various categories. Recently, Bulgari made headlines by reintroducing its ultra-thin minute repeater during the first day of the Geneva Watch Days. Piaget previously held the title for the thinnest tourbillon watch at the Watches and Wonders event.

However, a new contender has emerged from Eastern Europe. Russian watchmaker Konstantin Chaykin unveiled a prototype that puts him at the forefront of the ultra-thin watch category.
