Some practical findings for me personally based on this balance power table: - I always suspected that Bulgari thin movements were not designed to deliver great rate results, and the table proves this; - I always suspected that the Breguet's 10-Hz caliber...
What kind of errors and to which ratios are you referring? A remontoire’s only function is to ensure that the strength of the impulse to the balance is consistent throughout the power reserve.
That’s the idea behind the remontoire in the Lange 31 and RL Terraluna. But keep in mind that while the remontoire will keep impulse (and therefore amplitude and balance power) stable throughout the power reserve, it doesn’t necessarily mean those values ...
