Since its debut in 2013 the award-winning Logical One was an immediate success and surprise, a beautiful creation from Romain Gauthier with the main feature that is the ruby-link chain complication which helps to maintain a constant force for almost two days!
The round case of 43mm is available in white gold, titanium, rose gold or platinum. An off-centered dial indicates the hours & minutes on a stunning oven-fired enamel dial – the small seconds counter is integrated to the main dial and gives an elegant extension and finish of the dial • the incredible caliber is visible from both sides and through the sapphire case-back you can also have a look at the power-reserve indicator of 46-hours And in a world-first, the movement is wound via an ingenious, ergonomic pusher⠀⠀⠀⠀⠀⠀⠀⠀
*The present watch is a limited edition of 5 pieces in black ADLC titanium but the crown and pusher are in white gold.
