This Longineaster Retrograde Moon Phase is another development based on Longines‘ proprietary calibre L707, which is based on the ETA A07 from the Valgrange line. The quadruple retrograde module is exclusive to Longines, and this version now featureoon phase and day/night indication besides full calendar and independent time zone. The watch is available either in 41 mm or 44 mm of diameter.
ETA Valgrange line is based on the Valjoux 7750 chronograph: the chronographic functions have been left out and the plate has been enlarged from 13¼ French lines to 16½, in order to adapt to bigger case sizes. Winding in one direction, the calibre Longines 707 features the Incablock shock protection and the eccentric fine-tuning screw of the 7750. Running frequency is 28,800 A/h (4 Hz), power reserve is 46 hours, and the thickness of the movement has been increased to 10 mm to accommodate Longines’ proprietary module.
