Montblanc

So close, so different at the same time. 44 mm polished case, without beveled lugs, on your left / 40 mm brushed case, beveled and thinner lugs on your right. Both mono pusher Chronographs, but one is located in the crown, while the other is at 2 o clock....  

I would have to see it in the flesh. Your pictures make it look almost vintage. Very cool.

. . . less compact? I thought it was more, Nicolas. Confused, Art

Maybe I'm just spoiled by the dial of the blue version, which is near perfect. M4

heard from a VERY SERIOUS COLLECTOR that the earlier versions have better finishing... these would be dated in the very early blue dials... why? Once MB saw the popularity (let's face it--they never had a hit on their hands) they increased the production ... 

For a Mulltibrand-collector one is enough. I love more the green one. Best Walter

The 13.21 is the one inside the 44mm version right? The movement is more compact and yet the case size is bigger?

Okay now that makes sense. Thanks nico!

My bad for the assumptions!

Mainly because of the size. As we already have discussed it would be nice to see it with the pusher in the crown like it's big brother. Vte

I like the size and case of the 1858 Monopusher better but prefer the dial colour of the 1858 Tachymeter. As to movements, both are finished to the same level, so... So are you tempted to get the other one, too?

btw This 44 mm blue monster is saying hi! ...  

Enamel like Robin’s is certainly the way to go!

But I would pick the 40mm green version. Dave

but I have decided they are a bit too big for me. Size is the primary driver.

The monopusher on the crown does it and that blue gives you that sensational feeling ) If I would have the option and the money I’d go for the blue 44mm
