Technicals & product development
Optimized seconds-hand steps
We have enhanced our second wheel, intermediate wheel and rotor components to bring even greater precision to each seconds-hand steps.
The improvements relate to the 8¾''' to 11½''' size RONDA powertech 500 series, though not all these products will be modified at the same time. The enhanced components are already being used in the following calibers:
– 11 ½ ''' 512, 513/S, 515/S, 515.24D, 515.24H, 517, 519
The multifunctionals will follow from January 2016:
– 10 ½ ''' 502, 503/S, 505/S, 505.24D, 505.24H, 507, 509
Remaining modells will follow in the second semester 2016:
– 8 ¾''' 582, 583, 585
What is important here in terms of watch repairs?
In both the enhanced and the previous version of these movements, the second wheel, intermediate wheel and rotor form a single unit. So when replacing individual components here, please note that the two different versions should not be combined. A production code will be marked on the main plate indicating the version used.
You will find full information in the corresponding Technical Instructions which will be continually revised.
