The 2012 version has a longer power reserve, a bigger case and a very different dial. But the Datograph from 1999 remains my favorite, still. A better balanced dial, less empty, purer. And 39 mm works very well for me, as well. What about you? Best, Nicol...  

It just looks and feel better!

I like the II, IV, X on the original.. and the newer power reserve indicator breaks the dato triangle.. But the original is too TOP heavy..

This is also the same for their Datograph Perpetual, which otherwise will be my choice to compete with the 5270/5970s. Also I believe you need a deployant for this Dato or it will not wear well. The 1815 WG I have is already quite heavy so I can imagine w... 

That’s what pushed me to the Up/Down despite the larger size.

I like the smaller case. IMHO

Never ordinary, eh? Stunning.

It still remains one of my all time favorite watches. That this time around will not leave my collection.

vested interest lol.

I like the size, the balance of the dial , but the cupped caseback makes it uncomfortable to wear as a daily watch at least on my wrist . I tried it on deployant as well as pin buckle and I find the pin buckle more comfortable.... So in short the original...  

...  

No doubt

So I actually vote new. (of course the original will always be the original and that always has importance)

better proportion.

my favorite chronograph! Well balanced dial and perfect size for my small wrist. 405 sits on the wrist not so perfect... WBR Serge

The perfect size, the crowded yet extremely readable dial, it all works. Yes it’s a pity about the power reserve, but who would complain about having to wake up to winding this beauty every day 😀

I have tried on both. The original Dato was the first watch that changed my perception about everything related to watchmaking. It was/is a masterpiece and a classic. However... As an evolution rather than a revolution, I think Lange improved on the origi... 

how do the two compare? Cheers

From pictures and specs, I always preferred the original. After actually handling both and comparing side by side, I prefer the more modern dial and the better dimensions of the up/down.

I have quite a big wrist and the original Dt does not sit properly on it. Though, I like the original dial layout more. ...  

But to get the real feel i have to see them. Just to get the proportions. 39 mm is fine to me, that is a great pro of the 1999 model.

both are top cool pieces... when I have tried them I have liked the way the modern version sits on my wrist a marginally better. sits lower and less top heavy... pure aesthetics I favor the original... both are great however. Now if I had to choose and vo... 

Just because this post is gonna drive the price up for the Mark I and I want one 😂 jokes aside, I can’t find fault with the Mark II Datograph. They are both stunning in their own right. Original is favored because it is the one that started it all...and i... 

Mr. Blümlein was a true watch lover and understood how to make watches. He was a true business leader and not a press man. Unlike his successors... He just got everything right ... Lange 1, 1815, Datograph...

Original for me, roman numerals and a smaller dial just compose the watch better imo plus I genuinely dislike the case enlarging trend going on in the industry

I have the original and prefer it. I forgot it has Roman numerals. Never thought about it. I like the balance of the dial more and size.

Of course the original is a classic but mainly for the movement. For me it was too small, I don’t like Roman numerals on a chrono, Lange is known for the gothic numerals, and the power reserve was pretty short. When the Up/Dn came out in 2012 I knew it wo... 

As much as I love the original but I always believe in buying the best and most technically advanced version of something and let it age with you. Plus to me, having a a power reserve indicator is very important as I find it the most useful complication i... 

I much prefer, and own, the new version. The larger size suits me better for my wrist but I also find the power reserve both handy and visually appealing whilst I find the original dial to look a little too cluttered with the Roman numeral’s crammed into ... 

Despite generally preferring larger case sizes, I much prefer the dato in 39mm

I refer the larger case dial and longer power reserve. The addition of a power reserve indicator is also useful in a manual wound watch

Any watch over 40 (I believe) may have trouble looking dated over time. The sweet spot in size is 37-40 for any style watch in my opinion.

I like both but partial to my original. Dave ...

Power reserve, and I don’t like Roman numerals
