With the Omega Speedmaster 321 out, it is anyones guess who will come out on top Who knows? You decide!Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin vs. A. Lange S?hne Datograph Up/Down LumenWow, that is a cumbersome sub-heading. Perhaps I exaggerated the names of each watch to their full titles for comedic effect. But it does demonstrate the might of these horological heavyweights for our concluding quarter-final round. The heft of the model names correlates to each timepieces mass, as this round features the two of the few precious metal pieces that made it to the head-to-head stage. On the left, dressed in the finest garments, is the Vacheron Overseas QP in pink gold and alluring blue dial. In the right-hand corner is the Lange Datograph Lumen in illustrious platinum.Richemont Royal RumbleInterestingly, both quarter-finalists beat out the previous round contestants by taking 64% of the voting share apiece. The Overseas clipped the wings of the JLC Master Control chronograph with sector dial from Bens group. In the battle of luminescence, the Omega SpeedyTuesdays glow lost out to the translucent Lange Lumen in Berts picks. Now the showpieces of Richemonts most prestigious brands face each other for a place in the semi-finals. The Overseas is an ultra-thin self-winding perpetual calendar, whereas the Datograph is a manually-wound, ultra-thick chronograph, with an outsized date complication. Even so, the pricing is only separated by 7,200, with the Lange at 101,700 and the VC just under at 94,500.Ben Vacheron Constantin OverseasI am absolutely over the moon that the Overseas has made it this far in the 2021 March Mania competition. Not only was it my top seed from the preliminary twelve, but the Overseas was also easily the coolest watch I went hands-on with last year. The Caliber 1120 QPSQ/1 accounts for each months relevant days, without calendar adjustment, to the year 2100. This even includes the additional day in February during leap years. At that point, a slight correction is required, and the watch can continue for another century. The 22-karat gold rotor provides reassuring inertia. Sporting the Geneva Seal, this movement is confirmed as having been fabricated and assembled within the Canton of Geneva.Now with the tech talk out of the way, lets get to the real reason this valiant Vacheron has bested the onslaught to get to this stage. It. Is. Drop. Dead. Gorgeous. The third generation Overseas is already a knockout with a case shape thats finally found its form in its third generation. Combine the seamless integration of the case and bracelet in pink gold, and already the temperature rises. The final slam-dunk came in 2020 by incorporating the jaw-dropping deep blue lacquer dial from the time and date model. The balance is beautiful, with precise placement of sub-dial indications. Even the logo sits comfortably within the curvaceous notch of the moon-phase aperture. This Overseas oozes luxury without ostentation.Bert A. Lange S?hne Datograph LumenI guess we all saw this coming. Lets face it: there are 1 seeds and there are 1 seeds. If youre looking for the definition of dominant, look no further. The A. Lange S?hne Datograph Lumen steamrolled the competition to this point and looks likely to set-up a semi-final date with its catalog mate, the Lange Zeitwerk. Choosing between those two powerhouses would be a real tricky do, but the situation here is clear: the Datograph slays the Overseas and it isnt even close.Haute Horlogerie is a wonderous world, but it is, every so often, rightly accused of yawn-inducing stuffiness. Even the Overseas regal pairing of pink gold and blue cant elevate that snooze-fest to the levity expressed by this luminous Lange. Whoever decided the Lumen concept could be applied to A. Lange S?hne watches without completely undermining the brands integrity deserves a medal. Or maybe an honorary Geneva Seal? On paper, it sounds ridiculous. In practice, the Lumen is sublime.Fusing traditional horology and the brands aesthetic calling cards with a glowing phizog, even the blackest badger and friendliest friend of Max B1sser would be proud. And yet, perhaps through a mixture of high-quality execution and a ferocious force of will, Lange has done it. The result is so spectacular, Im anointing myself the favorite to take home this crown; just call me Bert Champ already. I expect Ill have to go through the Zeitwerk and perhaps the Czapek (if it can make it past the last Speedy standing), but I do not doubt this models potential for greatness.I was robbed in the Speedmaster World Cup semi-finals my pocket picked by that damn beagle that went on to split the vote against the ultimate champion, the Cal. 321.
