Eterna Caliber 3907M

Manually wound, column-wheel flyback chronograph of Eterna's modular Caliber 39 family, with a stacked register at 3 that counts both elapsed minutes and hours, running seconds at 9 and a date at 6 (Oak & Oscar, Worn & Wound). Worn & Wound (2017): 4 Hz, 60h power reserve, and Oak & Oscar's Jackson was the first watch to use a manually wound version of the 3916 (the 3916A is the automatic). Jewel count from Oak & Oscar's spec list. Eterna publishes no public data sheet for it, so diameter, height and hacking are not recorded. The 3907M is the same movement without the date.
