Introducing: The A. Lange & S?hne Lange 1 In White Gold
In addition to the Lange 1 Tourbillon Perpetual Calendar, A. Lange & Söhne has decided to add a white-gold 38.5 mm version of the Lange 1 to the collection. The Lange 1 is already available in pink gold, yellow gold, and platinum. 1 OF 2 The new Lange 1 was released at SIHH in 2015, and was one of our favorite releases from last year. It was completely rebuilt with two changes to the dial: a thinner bezel and a slightly less pronounced “A” on the dial signature. They also added a new caliber movement, the L.121.1 manual winding movement with a 72-hour power reserve. The watch you see here is still the same with the exception of the white gold and added lume to the hands, which will surely be a big hit. 2 OF 2 Check back here for pricing and more photos, and for more information on A.

Is the ROO Diver more durable than a 15300?
Hi All,I've had a 15300 for around a year now and have had a lot of issues with the durability of the watch. I love the look of it, and am thinking about trading up to a ROO Diver, but are there extra measures to make sure it is durable in place? I know it has the same movement as the 15300/400 series.Or should I not expect any Royal Oak to be as durable as a Submariner?(Note, when I speak of durability I mean wearing it playing sports and having issues)Thanks!
