What distinguishes it
Look beyond the reference.
Quartz regulation and a stepping motor replace the balance-and-escapement timebase. This is a useful baseline when comparing mechanical complexity with everyday convenience.
For the enthusiast
The cited Ronda sheet specifies battery 371 and a height of 3.25 mm over the battery, versus 3.00 mm for the movement. Nominal battery life is not a winding reserve. Document dated 2013; verify the exact supplied version.
