I was mostly looking at the amplitude, which I recall was around 280 with the lift angle set to 52 degrees (a good assumption until we know better). Given the case construction and the use of those five lobed RM screws, it will be a pain in the ass to regulate these watches once they are in your possession. Not the regulation itself of course, that's trivial given the standard balance design, but getting into the watch to access the two levers will be a pain for most watchmakers unless they have tools for those pesky RM screws.
