Super nice trio but...
Technically, Spring Drive is not quartz and does not use a battery.
AI says: Seiko Spring Drive is not the same as a traditional quartz movement; it is a hybrid technology that combines a mechanical mainspring with a quartz crystal for precision regulation. A
standard quartz watch uses a battery to power a circuit that sends a
pulse to a stepper motor, while a Spring Drive uses a wound mainspring
as its power source and an electromagnetic brake, regulated by a quartz
oscillator, to control the speed of its continuously sweeping hand.

Nice collection!

I don’t have a UFA but the rest haven’t been bad luck, unless you count all the battery changes over the years… I’m very happy to see love for these unappreciated but technically superb watches. Not counting Spring Drives; there have been too many 🙁 Insid...

Of course I took pictures showing my watch, what I couldn't capture was how hard it was to read with slim hands on black dial and glossy crystal. Another one I sold without replacing it with a more legible model... like this! ...
