The Logic 2 is the updated version of our classic Logic watch. The Logic 2 now features a Swiss movement, known for its accuracy and quality. It is still one of world’s thinnest 100M-rated watches but now without the screw-down crown. The Logic 2 is able to achieve the 100M-depth rating due to a unique triple o-ring seal design. The Logic 2 also features a date magnifier for increased legibility. The Logic 2 is perfect for those who like a simple, slim, professional watch. The 36mm mid sized case fits men and women alike, all with the Momentum offset crown position for maximum comfort.
