Twenty-8-Eight Tourbillon Prestige

The Twenty-8-Eight Tourbillon Prestige, which contains DeWitt's DW 8015 calibre, features a Tourbillon alongside the patented Automatic Sequential Winding (A.S.W.) which DeWitt first presented in 2010.

This mechanism, which is driven by a peripheral oscillating weight, ensures a constant flow of energy to the gear train thanks to the sequenced winding of the barrel. This allows the use of a manual-type barrel, and avoids the running errors that can occur when slip springs are used in a conventional automatic movement.
