Lots of attention lately on the calibre 16.29 on the new 1858 chronograph tachymeter.
Let's not also forget its smaller brother the calibre 13.21 found on the Montblanc Villeret vintage Pulsograph, the Heritage Spirit Pulsograph.
Below are some pics of the calibre 13.21 on my Montblanc Villeret chronograph grand feu enamel.


And of course, the more recent star, the larger calibre 16.29
On the new Montblanc 1858 Chronograph Tachymeter

Picture by Constantin. Calibre 16.29 on his Montblanc Villeret Grande chronograph grand feu enamel.
Both are beautifully designed and finished chronograph movements. Not the most innovative chronographs but definitely the most traditional ones.
Which calibre do you prefer. Note the 13.21 is on watches 39.5 to 41mm whereas the 16.29 is on watches 43.5mm to 47mm.
Cheers
Robin
