Geneva based Swiss luxury watch manufacture DeWitt unveils the Academia Grand Tourbillon watch, a limited edition of 99 pieces, entirely conceived and assembled at the DeWitt Manufacture by its own master watchmakers.
This new Academia creation houses the calibre DW 8030, developed from the DW 8028 movement, the Manufacture's first 100% in-house manually-wound tourbillon movement, first presented in 2010. Built out of 327 component parts, this calibre is structured along traditional lines and incorporates numerous tried and tested technical features: 18,000 vph, a 65-hour power reserve, a Swiss lever escapement and a Straumann balance-spring with Phillips curve sequenced at 2.5 Hz.
Dressed in a circular 46 mm rose gold case and adorned with the famous imperial columns, the Academia Grand Tourbillon watch is one of DeWitt's most emblematic timepieces.
On the reverse side of the watch the sapphire case back reveals a day and night indicator, which takes on a blue colour tone to indicate night-time and a white colour tone to indicate day-time hours.
