Introducing the world's first concave crystal watch. Marriage of wine, time, and ergonomics. Made in Princeton, USA. We are pleased to announce the arrival of Sablier Watches. Best known for one of its distinct design characteristics, the patented concave sapphire crystal, the Sablier timepiece is unique and elegant, both functional and sophisticated. The Sablier watch dial was designed to make for easy reading with the hour hand wider than the minute hand and the index hollowed out in the location of 6, 9 and 12 hours. This combination of beauty and function in design are true ingenuity and the hallmark of all Sablier watches.
