Boutique watch brand Cecil Purnell, founded in 2006 and named for founder Jonathan Purnell’s watchmaker grandfather, bills itself as “the only haute horlogerie brand crafting exclusively tourbillons.” Its product line uses all in-house-developed tourbillon movements, many of which add additional complications such as big date indications and hour strikers. In 2014, Cecil Purnell launched several new movements, notably the one used in its new Twin Tourbillon CP-V15 watch. The two tourbillons in this timepiece, visible in the lower half of the sapphire-chromium dial with applied Roman numerals, are linked together by a differential in a system that is intended to ensure greater timekeeping precision. Both tourbillons in the double-barrel movement rotate clockwise at 3 Hz. The contemporary regulating system, with two gears and a spiral, ensures that the tourbillons cages regulate one another’s speed and work to increase the precision of the mechanism. The modern-yet-classical case, designed by renowned watch designer Stephane Lacroix, is available in white gold or rose gold.

I feel like a tourbillion discussion should include Thomas Prescher. His tripple tourbillon, and mechanical mystery are staggering.
Obviously would take the Greubel Forsey here, in my opinion the best finishing out there. Definitely up to par with, KV, P Dufour, and better than Patek any day…. They are the watches of all watches IMO. Their stealth tourb are amazing….
Love seeing what they come out with every year. Please, no more Big Bang Tourbillons, enough is enough, the Tag is sick too,
And Seagul just released a dual tourby for under 40 000 usd [and they already have single tourbies for under 1 000 usd.] and they perforn and outperform pieces costing 100 times as much.
out in Sept. 2013

The inner carriage is made by Titanium and the outer carriage is made by Aluminum, in order to reach a relatively low weight of the dual-axis tourbillon system.
Total components of the tourbillon system: 137
Silicon made escape wheel, in order to reach a better weight distribution. In addition to a free sprung system
6 microstella type weights on the balance wheel
hyper accurate
and about tens times less than a “swiss made” tourby.
swiss is in quotes for a reason
The commercially available version will be launched in late 2013, the presell price is 300,000 CNY (about 48,000 CHF
and it IS A REAL tourby unlike the panerai
the Panerai Tourbillon P.2005 is NOT rotating as we expect it doing it from a typical tourbillon, some colleagues and I simply called it the chicken grill when Panerai presented us the P.2005 in Florence some years ago. Even when the Panerai construction is meant to be a tourbillon one could discuss if this is really a tourbillon in spirit of Abraham Louis Breguet.
The TAG is sharp. I really like it. Not that I’d ever be able to afford iit.
