Watchmaker profile

Luca Soprana

Luca Soprana led collaborative movement development at Ateliers 7h38 for projects including Jacob & Co.’s SF24 and Astronomia, and reworked the Derek Pratt wristwatch project. 1

Workshop-visit interview preserves team credit. The Pratt continuation involved earlier work by Stewart Lesemann and Ron DeCorte; Soprana describes a newly designed movement, not an untouched original Pratt construction.
