The Insider - AUF/AB



A. Lange & Söhne Update the DATOGRAPH

written by A.Morgan - 19th Dec 2011

I don’t know what a proprietary oscillation system is, but I do know that I want one.

What I can tell you is that it’s one of the many new or updated features on the A. Lange & Söhne DATOGRAPH AUF/AB (yes, it’s supposed to be written in capitals), and regardless of whether or not it’s something that I’m even going to notice, I still love it. It just sounds so dastardly and so cunning that it ignites that little bit of Blowfeld we all have inside of us, inspiring dreams of world domination, silver lamé suits and fluffy white cats…

Truth is that it is merely a system for fine-tuning the movement to yet ever-greater accuracy, but an even more useful addition is the increased power reserve to a whopping 60 hours that has somehow been crammed into the 41mm case. This is where the AUF/AB bit comes in – literally translated as ‘FROM/TO,’ or ‘UP/DOWN,’ or ‘ON/OFF,’ it can be found on the power reserve indicator that has been added to the dial to help keep track of the three-days plus worth of power from the manual wind movement.

Oh, and the movement – it’s never a surprise (but always a pleasure) to see a beautiful, elegant, breath-taking movement inside an A. Lange & Söhne, and this one is no exception. The calibre L951.6 (complete with larger mainspring barrel for the additional twenty-four hours of power reserve) is one of the most impressively decorated chronograph movements ever to have existed, and is also blessed with a flyback function (allowing the user to stop, reset and start the chrono in one button push) and a clear sapphire caseback through which to coo at it from.

Dressed in its platinum case, the DATOGRAPH AUF/AB is perhaps the most complete chronograph watch available for sale today, so if you can find the not unreasonable amount of cash required to buy one, do it – after all, everybody, and I mean everybody, needs a proprietary oscillation system in their life…

Think of a digital watch and you think of that great little Casio you had as a child with the backlit display and more alarms than you knew what to do with. At that age, the watch you craved wasn’t a Patek Philippe minute repeater... more
