Talking about his work here, we have the Prestige HMS, one of the early calibers Romain created ( the first is the HM ). His caliber 2206 movement was thoroughly developed, designed, produced, assembled, and regulated by him. Showing the Vallée de Joux style finger bridges that have some of the hardest to do sharp-corner/angle anglage, the bercé anglage (rounded profile of the bevels) is one of the most complex techniques to master, too much it started losing the shape, too little it will not give a mirror finished, that's why Romain Gauthier can make only 40-50 watches per year, only a handful of people can complete such task.
