when i think of jewelers regulators the first things i think of are porcelain dial, sweep second hand, and (more typically) a 13lb ginormous brass pendulum.
posted his waltham, above... but in another thread andy dervin just clarified while waltham made a medium-sized movement with sweep second hand, it was typically in 40" or so cases... and that they did not make a seconds beating movement with a sweep second hand.
i love jewelers regulators and was starting to google to research more about history, desirability (apparently waltham didn't think there was a demand for sweep second hands), etc.
so: what defines a jewelers regulator? is a sweep second hand a definer? would it be more accurate to call steve's a precision regulator than a jewelers regulator?
here are mine:
- waterbury no. 8 w/ deadbeat movement
- french pinwheel in somewhat unique case with beveled and cut glass in door
- gilbert #20 movement, newer/custom case, dial and pendulum
- french pinwheel in ridiculously heavy case (with a brass plaque that says "johnson pneumatic tower clock, erected by johnson heat regulating co., st. louis')
- older pinwheel, no case, made up pendulum, pewter hands (liked the look)
