Equipped with twin barrels like all mechanical movements by Technotime, this tourbillon provides an over 120-hour power reserve. This extremely flexible calibre is capable of housing other complications, including a power-reserve indication, retrograde date or any other specific modules developed by clients. This movement equipped with Technotime balance-springs may be personalised in accordance with customers’ wishes and boasts excellent chronometric performances that mean it may be configured to earn COSC certification. The Tourbillon TT791 combines performance with a degree of reliability tried and tested by the Chronométrie 2011 International Timing Competition, in which Technotime took third place with this daring calibre.
