Introducing: The Parmigiani Fleurier Tonda 1950 Tourbillon
The tourbillon is a somewhat questionable complication down right up ’til the present time, and for a few reasons. First and foremost, some quote specialists unquote don’t think of it as a complication by any means, however a directing gadget (it doesn’t show any information). Besides, there is some discussion about whether it really does what it should do (there is, obviously, no expansive agreement on the question).
The third protest is the most straightforward to comprehend: the tourbillon channels a lot of energy from the heart before it can reach the escapement and balance, and the escapement and equilibrium are on short proportions in any case. In a non-tourbillon watch, the fountainhead at last needs to convey barely sufficient energy to keep the equilibrium swaying at a sensible amplitude – yet in a tourbillon, it likewise needs to move the whole tourbillon pen and every one of its contents each and every time the escapement opens. This is a totally monstrous extra energy requirement, and there are two ways to overcome it. One is to siphon more energy into the framework with a more grounded fountainhead, yet this savage power approach implies more wear and greater precariousness all in all in the watch. The other approach is to make everything extremely precisely to diminish energy misfortunes because of grinding to a base, and to make everything as light as could be expected – particularly the confine and escapement. Consequently the investigation, in current tourbillon making, of additional light materials and amalgams in the confine (like titanium) and the overall rule that the enclosure ought to be pretty much as gossamer fine as possible.
Now envision you want to make an extra dainty tourbillon. Promptly, you have an issue in light of the fact that a level watch implies a level heart barrel, and a level origin, which implies much less torque. It additionally implies that there is no edge for blunder in development of the going train – which is a challenge enough in a non-tourbillon additional level watch. What’s more, now, imagine you want to make an additional level self-winding tourbillon – now you need to keep things level and sensibly compact but somehow discover space for the automatic winding rotor, and the automatic winding framework and you need to somehow have sufficient mass for the rotor for it to wind proficiently – all without making the watch unduly thick.
And that basically is why you see scarcely any super slight self-winding tourbillons. The absolute first, obviously, was made by Audemars Piguet right back in 1986, and their Caliber 2870 was just 5 mm thick in general. It had an uncommon sledge type winding framework with an iridium wavering weight and to keep things thin, it had an extremely unordinary architecture in which the rear of the case really worked as the top plate of the development. There was no arrangement for hand-winding (you needed to delicately shake it to wind the origin) and it had the absolute first titanium tourbillon confine at any point made, which was just 2.5 mm thick and 7.2 mm across.
It pushed the limits of then-current watchmaking so hard that it didn’t really work very well however in numerous regards it addresses the initial moves toward the advanced super slender automatic tourbillon – a tiny family that has, with the expansion of the Tonda 1950 Flying Tourbillon, just gotten altogether bigger.

The Tonda 1950 is the extent that we have had the option to decide, the most slender self-winding microrotor flying tourbillon in current creation; now, the world isn’t actually awash in competition for that particular title, however records are to a lesser degree a point here in essence than they are as a sign of what the watch achieves technically and stylishly. It isn’t that there are any really extreme arrangements in the Tonda 1950; what there are, are known arrangements that have been advanced and adjusted in a truly canny and elegant way. (By and large, the weight of a solitary raindrop). To keep things as level as could really be expected, the automatic winding framework depends on a microrotor, which is made of platinum to expand proficiency (and flawlessly and elegantly engraved for sure). What’s more, there are bunches of little touches that taken all together address a truly praiseworthy collection of art – perhaps the most prominent and recognizable is the blued steel seconds hand that is an indispensable piece of the carriage. And furthermore, in the help of keeping things as level as could be expected, it’s a flying tourbillon – the shortfall of an upper tourbillon connect allowing for the shaving off of extra microns.
One of the most pleasant parts of the watch, coincidentally, is its dial – our own has a dark jade dial and the lacelike white striations appear to be particularly fit to the production of a ultra meager flying tourbillon (it tends to be had with a mother of pearl, white jade, or “Chasm Blue” dial brightened with Geneva stripes too). The development, type PF517, comes in at 3.4 mm thick and conveys, in spite of the compromises characteristic in additional level watchmaking, an entire 42 hour least power hold; the whole watch is 8.65 mm thick.
Though it’s not the most slender tourbillon at any point made, it doesn’t actually should be, or to say that it is, to have the option to invest wholeheartedly in what it is: a very well executed and in its own quietly rich way, exceptionally fearless tourbillon wristwatch – an example of the victory of patience over garishness, value (MSRP about $130,000) notwithstanding.
