Rolex Ovettone – the legendary clocks of which the world forgot


Lange & Söhne Datograph Up / Down If you think about it, almost any hour of top brand with a history in the arsenal of products produced by it have a chronograph watch with manual winding, horizontal clutch and control via the column wheel.

Clock, the mechanism of which to be proud to show to friends and acquaintances, enjoy yourself.

After classical subtsiferblatami arrangement with two, one of which is a small seconds indicator, and the second – 30 minute chronograph counter (central hand acts as a stopwatch, a chronograph) traces its ancestry from the second half of the 19th century.

Indeed, it looks as models Vacheron Constantin Patrimony Traditionelle Chronograph, Breguet Classic Chronograph and Patek Philippe ref.

5070, based on the Lemania mechanisms.

Or Patek Philippe ref.

5170 with a new caliber CH 29-535 PS, inherited from the layout of the same Lemania.

And it is in such an attractive manner serve A.

Lange & Söhne Datograph watches, presented in 1999.


Lange and Sohne DATOGRAPH (Platinum / Black) Ref.

403,035 However, the layout of the dial supplemented double window “large” dates located at at “12 o’clock”.

This patented calendar mechanism consisting of 66 elements, first introduced in 1994, was jointly developed by Jaeger-LeCoultre specialists and is proud Saxon manufactory – one of the ten most iconic innovation which found a place in groove A.

Lange & Söhne.

the layout of the dial Moreover, L951.

1 caliber has two more proprietary “lotions” – Flyback return function and chronograph minute counter, which is done by the indication “jump” of the minute hand through the corresponding measurement interval.

Flaybek chronograph allows one to carry out pressing restart mechanism directly during the current measurement, in actually performing an instant three operations: stop, reset and started.

This feature was especially popular at the dawn of the 20th century during the time of rapid development of aviation, then its popularity has fallen, but the engineers A.

Lange & Söhne was able to put it into its modern developments.

As to the “jumping” minute counter chronograph, this feature took place back in the pocket watches.

The current interpretation of it not only improves the visualization of the reference readings, but also demonstrates the high level of the German school hours.

In addition, the change of the minute is accompanied by very pleasant to the ear-click .



It should be noted that the model proposed in the housing Datograph 39 mm and a thickness of 12.

8 mm is used as material 18 carat pink gold (in combination with a light dial) or platinum (dark light).

Nevertheless, even such wonderful watches as Datograph, sometimes need to be updated.

And just at the moment, a few weeks before the opening of the SIHH-2012, the company from Glashütte presents a new model – Datograph Up / Down.


Lange and Sohne Datograph AUF / AB As can be seen, changes in appearance are minimal.

The diameter of the platinum body is increased to 41 mm thickness is also increased to 13.

1 mm.

Furthermore, proportionally increased the size of the window and “big date”, by about 4%.

All the hour markers are made in the same style and have a rectangular shape.

The main innovation, through which the model and received a small supplement in the Up / Down title (Ab / Auf in the German version), has become a small disk power-reserve indicator is located at the position of “6 o’clock”.

As for the mechanical filling of the new model, it became L951.

6 caliber, also received a number of significant innovations.

Recall that similar mechanism L951.

1 it represents caliber with manual winding, platinum and bridges which are made of nickel silver, “German silver”, the physical properties of which are more stable in comparison with the usual brass.

caliber L951.

6 Specific words deserves oscillating system balance-spiral.

The balance varies with a frequency of 18,000 pc / h (3 Hz) and represents a new generation balances the variable moment of inertia (Gyromax type), which adjustment takes place by means of six adjustment eccentrics.

Traditionally, Lange balance bridge is supplemented control of the “swan neck”.

But the spiral of balance in this version has its own caliber, branded spiral Lange end turns Breguet replaced the spiral of widespread Nivarox.

The few factories can boast its own production of balance coils and extremely honored that A.

Lange & Söhne – one of them.

Here you can add, that all new gauges Saxon manufactory get a new spiral, in addition, it is used by other companies Richmont group, in particular, Jaeger-LeCoultre.

Another significant difference from the caliber L951.

6 L951.

1 became increased up to 60 hours of power reserve.

Additional 24 hours (at Datograph it was only 36 hours) provided a larger gain clockwork drum.

In this case, it is dictated by the values ​​of the power reserve, characteristic for modern watches with manual winding.

In conclusion, it should be noted the excellent quality of the traditional signs and finishing A.

Lange & Söhne mechanisms.

As branded items are: gold stones bezel, four of which are fixed by screws; polished plate on the escapement wheel stone; blued screws; hand-engraved balance bridge, as well as the already mentioned control of the “swan neck”.

Platinum decorated with pearl grinding Perlage, bridges and the surface is finished with striped glaskhyuttenskoy grinding.

You can not go past the immaculately processed chamfering and polishing quality of a number of components, in particular, the column-wheel.

Will there be a success updated Datograph? No doubt, because it was almost the same as he remembered the true connoisseurs of high watch mechanics for 12 years.

The only difference is that he has become a little bit more technically perfect – just enough to again be at the top among the good old chronograph with manual winding, with the usual classical column wheel.
