Review: Montblanc 1858 Tachymeter Chronograph Steel with blue dial – Part Two

 

Last week, we saw quite a few PuristS share live pictures of the Montblanc 1858 Tachymeter Chronograph on our Montblanc forum, including a new owner, M4, who just received his watch! I know that very soon another Purist will be receiving his, and I very much look forward to his incoming post. Never before has a Montblanc watch become a community watch on this forum - but now the 1858 Tachymeter Chronograph in steel or red gold is becoming our first Montblanc community watch here!


In part two of my review of this watch, I will be focusing on the Montblanc Villeret monopusher chronograph calibre 16.29, as well as some features of the 1858 Tachymeter Chronograph steel version (the red gold version has mostly the same features except the case material and the dial and lume colors).

We have seen many pictures of the blue dial on the 1858 Tachymeter steel edition — how it plays with light, the subtle sunburst effect, and more recently, the lume of the hour markers and cathedral hands. The last came via a picture shared by fellow Purist Alex 007.

The entire 1858 collection pays tribute to the year the Minerva manufacture started operations. What is the best way to achieve this? It’s to have the most beautiful, traditionally-crafted Minerva monopusher chronograph calibre available power this watch!

The calibre 16.29 is THE REASON why I purchased this watch.

The Montblanc Villeret calibre MB M16.29 is inspired by the original caliber 17.29 made by Minerva for wristwatches & pocket watches since the 1930s. The illustration below shows a comparison between the vintage and modern calibres.






Of course, the Minerva in the old days was not a haute horology brand and hence the finishing of the calibre was industrial. The traditional horizontal disc clutch architecture of the chronograph movement, the large V-bridge and slow oscillating balance wheel are still very appealing to me, even with an industrial level of finishing. With the calibre 16.2, we have the same traditional architecture but with much more attention given to the finishing of the movement including high-end techniques such as Côtes de Genève” patterning and sublime bevelling, use of gold chatons, rhodium-plated german silver chronograph bridges, the highly-finished Minerva arrow (which many of us adore), etc.


I will share some more macro shots from my watch here.



I love column wheels and here is a highly polished one on the calibre 16.29. The column wheel on this calibre will be even more attractive if it were larger, as it looks quite small proportionately to the super-large balance wheel and V-bridge.





One of my favourite features of high end watches is a large and slow oscillating balance wheel. This calibre 16.29’s balance wheel, crafted in-house at the Montblanc Villeret manufacture, with in-house manufactured hairspring (counted and regulated by hand), is my favorite in my collection.

And here is a picture with the technical specifications of the modern calibre 16.29.





Do you think the calibre 16.29 is a worthy successor? Personally, I definitely think so.

I had shared this video before of the oscillating balance wheel. Here is a recap:






On the dial, we all appreciate the beauty of the blue sunburst dial on our recent posts here on PuristSPro’s Montblanc forum. It was good that Alex 007 revealed the power of its luminous detailing, a feature I didn’t appreciate until his sharing. There is another feature we seldom discuss, i.e. the Tachymeter function.



The tachymeter scale on the outer periphery of the dial facilitates the computing of speed. Multiplying the value shown on the tachymeter scale via the second hand by the measured distance results in the correct speed. For example, if 1 kilometer is travelled in 30 seconds, multiplying the corresponding tachymeter value of 120 by the distance of 1 km equals a speed of 120 km/h. This works for miles too, for those few who still use that archaic unit (which was more popular in 1858).


Ok, I know most of us won’t be using the Tachymeter but to me, it is another of those old school charms we have in chronographs which I find fascinating especially as this is my first watch with a tachymeter scale.


Finally, I would like to share one more feature of this watch, which may not be important to everyone but it is to me. All Montblanc 1858 Tachymeter Chronographs will go through Montblanc’s 500 hour laboratory test and each watch will have its individual certificate.


Here is mine.


Here is a video on Montblanc’s Youtube channel on their 500 hour test.



Maybe I am a geek but I really appreciate my watch having gone through such a rigour and awarded a certificate to prove it. A fine detail and luxury if you ask me.

Hope you have enjoyed this two part post on the 1858 Tachymeter Chronograph.

To conclude, here are two pictures from the manufacture, on the hand finishing and assembly of the calibre 16.29.
