The stunning Double Tourbillon 30° from Greubel&Forsey
Thanks to the Greubel & Forsey AD in Paris, I had the opportunity to see and handle the Double Tourbillon 30°. Let's say it directly: it's a fantastic timepiece. The Double Tourbillon exists in two versions: vision (with a visible tourbillon through the o...
I prefer this one
I've never liked the openworked dial on the 30 degree one, I find it very ostentatious compared to the resdtrained, traditional frosted gold of the back. A...
The Invention Piece 1 is a masterpiece too.
I love the way the time display system is integrated into the movement. Fr.Xavier...
I completely agree . . . Invention Piece 1 is also among my favorite watches . . .
There is no denying that Greubel and Forsey and geniuses. Craig...
i love them all for their looks and technical detail
who cares if a tourbillon, double tourbillon or inclined tourbillon is superfluous for accuracy in a modern watch, they look superb and are very very clever. one question Xavier, are the seconds a dead second function? Graham
No. It's a "classic" second hand.
If you take the Double Tourbillon : you have the classic second hand (6 steps per second) + the indicator related to the Tourbillon. But your idea is very interesting ! Maybe a further development from Greubel & Forsey ? Fr.Xavier This message has been ed...
thanx xavier. i've enquired...
thanx xavier. i've enquired on the Journe forum about the technical difficulties, if there are any, of a dead second, but had no replies yet. logic would say its just a set of gears to drop the beat rate from balance to second hand, but i'm no technician....
Graham, here is a small graph.
Graham, Here is a small explanation from Journe's website: Hope it helps. Merry Xmas to you too ! Fr.Xavier...
thanx again xavier. i...
thanx again xavier. i think i understand it. not overly difficult or technical. either that or explained very simplistically :) makes me wonder why more people havent done it(other than a rolex in the 60's). i like the idea of a tick tick like my grand fa...
You can find dead seconds in several watches.
For example, you have a Chezard caliber which is a dead-second one. It was used by Panerai for its Radiomir Independant. Here is a pic from Haute Horlogerie.org : More recently, Harbring released a watch with a dead second. The caliber used was a Valgrang...
Here's also an explanation by Suitbert of the Chezard dead secs caliber from Panerai forum

For me too, The Invention1 is THE Masterpiece of G&B!
The 24second tourbillon are really interestiing too, as the "Secret" version of double tourbillon. For me, this watch (excluding of course Invetion cause she has no dial), have a problem with the dial, i can't imagine that this dial are of 300k€ watchs, i...
