Mkt33's post from 2014 highlights Montblanc's groundbreaking introduction of a mechanical perpetual calendar in stainless steel at an accessible price point. This article delves into the technical aspects of the MB caliber 29.15, developed with Dubois-Depraz, and offers an exclusive look at the module under the dial. It remains a relevant discussion for understanding Montblanc's strategy in making high complications more attainable for a broader audience.

Montblanc's debut of a mechanical perpetual calendar in stainless steel for under 13,000 USD  was a shocker at SIHH 2014.





Montblanc was able to bring  this type of "value" to the table was by working with Dubois-Depraz and creating the MB caliber 29.15.

The MB 29.15 is an unique movement developed and reserved for Montblanc's use exclusively.  If anyone doubts Dubois-Depraz's quality, then they should also start questioning the quality of the movements and components found in many Girard-Perregaux, Audemars Piguet, and Richard Mille watches.  Besides, every Heritage Perpetual Calendar watch will also undergo the Montblanc 500 hours quality test... very few perpetual calendar watches, currently marketed, are ever tested to this extreme.

We know the Perpetual calendar function is module build upon a Sellita base movement.  Honestly, imho, this is an advantage. Although I am sure many PuristS would have preferred an integrated Perpetual Calendar, for the collector who wears his/hers perpetual calendar infrequently, the ease of adjusting the calendar, the wide availability of servicing and parts replacement should be considered paramount.

Montblanc kindly supplied PuristSPro with pictures of Depraz Perpetual Calendar module under the dial.  This has not been shown anywhere else to my knowledge






Compare this with another version of a Depraz Perpetual Calendar module from the early 1990's. Notice some of the changes. Less springs, more levers and cams in the construction



Hope you enjoyed this inside look from Montblanc,

Mike

To say the least. Now, the question is to know who is targetted by this PC, colectors or more general buyers? I think it targets general buyers, not collectors. I mean a wider audience than collectors. Which is not negative " per se ". Montblanc offers a very afordable PC for those who dreamt about getting one, but couldn't afford it. Smart. Even if the JLC offer is close, in terms of price. Best, Nicolas

I think it can be a good way to introduce complication to a broader market at such a price point which in turn could create new interest in mechanical watches. Bravo to Montblanc Bill

I agree with Bill that it is indeed a good thing that Montblanc is bringing great value to the market, a very competitively priced mechanical perpetual calendar. Besides the accessible price point for such a high complication, your other post on the craftsmanship of the case, especially designed for the new Meisterstuck Heritage series also shows the value of craftsmanship Montblanc is demonstrating in their products. For many collectors who may already have Perpetual calendars, I do agree with

A really good value for a perpetual calendar. I haven't seen one in person yet, will need to stop by the local MB boutique to check it out. Thanks for sharing the pictures of the movement and the Depraz module under the dial. Regards, ED-209
