1 bph movement

hi
i just wanted to know why no one makes 1bph automatic movements technically they should have better power reserve but less torque right?

yes

soryy i meant seconds oh damm🙁

Rolex used to make a 1bps mechanical watch called the TruBeat - it was just a regular movement with a dead-seconds mechanism added. Not very popular in the end, though. You can read more here: http://www.hodinkee.com/blog/2008/1...eat-another-lesson-in-successful-failure.html

As for a modern day one, I don't think it would work from a marketing point of view. One of the big selling points of a mechanical watch is that it sweeps instead of ticks - it's the big differential between an automatic and a quartz. It may help increase power reserve, but automatic winding modules are so efficient these days, I'm not sure it would be necessary. Nice idea, though 👍
