Introducing The Montblanc Heritage Chronométrie Perpetual Calendar Sapphire

Recommended Posts



Creating affordable complications is nothing new for Montblanc. For the last few years now it's even been one of the watchmaker's signature moves. Today we're getting a refreshed take on a perpetual calendar first released in 2014 with the Heritage Chronométrie Perpetual Calendar Sapphire. This watch is a pretty straightforward 40mm stainless steel perpetual with an automatic movement, but with a twist: the dial is smoked sapphire so you get a good look at what's going on underneath. Stylistically it's a nice balance of traditional and modern, and the blue accents at a lot of richness to the dark sapphire. Importantly the price is still well under $14,000, making this one of the more affordable perpetuals on the market today.

Initial Thoughts
I've got to say, this is a really smart move from Montblanc and a thoughtful execution. One of the complaints often associated with perpetual calendars is that the actual QP works are what's called cadrature, which means they sit just under the dial far out of view of an open caseback. By using a sapphire dial, Montblanc is letting its customers get a good look at the complex mechanism at work. I'm also glad that the brand opted to go for a more restrained 40mm diameter, which at a sub-10mm thickness is extremely wearable for most people. I haven't see one in the metal yet, so I can't truly weigh in on how the watch looks and wears, but this one has a lot of potential based on this early look. Stay tuned for more, we'll be getting our hands on one of these shortly.
