Calibre Valgranges A07.161

Based on the legendary Valjoux calibre, the new Valgranges calibre meets the growing demand for watches in large diameters. The A07.161 version with date features a noble and useful complication, the power-reserve indicator; the ballbearing disconnecting-gear system relieves tension on the buffer indicator when the spring is fully wound.
