The Montblanc on the dial is small enough for me, so I'm fairly happy with that. No major complaints on that one. But in terms of dial design, the design, the fonts and material used, the ink color used, I wonder if it will age well. Will it still look good 20 years from now? Or does it look modern today, only to look dated tomorrow?
The case is much too thick, we're in full agreement there.
The movement is better than one can expect in this price point. It is an off the shelf movement, but I would actually consider it a very integrated movement rather than a layer cake movement. But yes, a more noble movement would be better. Keep in mind, the Patek Philippe World Time is not an integrated movement and is very much a modular/layer cake movement. But despite this Patek Philippe's movement is still thinner.
The comparison in my mind between a Patek Philippe 5110/5130 is still going on. A 5110J, 5110P, 5130R, or a 5130P are still pieces I would like to own. And you know I love the micro-rotored 240 caliber too... And you're right, the rose gold for rose gold is only 3x the price, and even less if one considers a gently and carefully used version.
The Montblanc is a true bargain. It's not perfect, but only true PuristS whom understand movement finishing and architecture, will recognize the difference between this watch and one of its more expensive cousins from Vacheron Constantin or Patek Philippe. I recognize these differences, yet I'm still intrigued by this Montblanc Heritage Orbis Terrarum. It's just that good.
