KMII provides a quick review of the Montblanc Heritage Chronometrie ExoTourbillon Minute Chronograph, a complicated timepiece that combines a one-minute exo-tourbillon with a chronograph and date display. The author highlights the in-house MB R230 caliber and the captivating black aventurine dial. This article offers a detailed look at Montblanc's haute horlogerie offerings beyond the Villeret and 1858 lines.
The Rolex Bubble Back, reference 1858, represents an early example of Rolex's self-winding waterproof wristwatches. This reference is part of the broader Bubble Back family, characterized by its distinctive domed case back designed to accommodate the thicker automatic movement of the era. It showcases Rolex's foundational efforts in developing robust and reliable automatic timepieces for everyday wear, laying groundwork for future Oyster Perpetual models.
This particular reference features an 18k white gold case, measuring 38mm in diameter. It is fitted with a sapphire crystal, protecting a silver dial. The watch is powered by an automatic movement, specifically the Boucheron 1858 caliber, offering a power reserve of 42 hours. The fixed bezel and leather strap complete the watch's classic presentation.
For collectors, the reference 1858 holds interest as an early and relatively rare iteration within the Bubble Back series, especially in white gold. Its larger case size for the period also makes it appealing to modern tastes. The presence of a date complication adds to its functionality, distinguishing it from simpler time-only Bubble Back models and highlighting Rolex's early integration of practical features.
Nevertheless, I regret that all the sub dials are too concentrated and a too small ExoTourbillon for the case size of this timepiece in my opinion. It’s a little bit like if Montblanc didn’t know which element of its watch they wanted to highlight (Aventurine, Tourbillon, sub date dial...). This dial mainly lacks of “breathing” for me. A better layout and it would have been much much better in my opinion. My two cents. Best wishes Alkiro
The overall R200 architecture only allows for a certain layout, I guess. Do you prefer the overall balance of the TimeWalker ExoTourbillon Minute Chronograph, which uses the same movement? Thanks for your input, Alkiro!
And one easier to solve without a chronograph complication, as shown by the Slim...
Not just thorough, but you make interesting points when you compare the watch under the microscope with others from the same brand; or with similar complications.
I will try to make more in that case
KMII, Thanks for the review. When I saw the photo, my initial though was: "He should have wiped the dust off the glass," Then, I realised it was not dust on the glass but the cosmic highlights on aventurine dial. I like the Rieussec chronograph layout that works well for that model but adding a tourbillon is distracting. The good news is that the tourbillon does not affect the reading of the chronograph counters. Overall, with that Montblanc Star diamond and the cosmic dust, I think this is a "f
