After the deconstruction, the only problem I found, is that the Centre Wheel shaft was broken at the Pinion end. So I will need to need a replacement or make a new one!

it does one thing, and one thing only, which is let you vibrate a balance spring. This tool is used to let a watchmaker determine the correct active length of a balance spring, once it's attached to a balance – in other words, make sure the active length of the balance spring is such that the balance is beating at exactly the correct frequency.
I thought I would post this excellent video by Breitling Watches on Remembrance Sunday
Lest we forget.
Breitling is proud to celebrate 100 years of the RAF as
Official Watch Partner to RAF100 – journey to discover our short film series,
directed by David James Gandy, depicting the past and present of the RAF, and
the heroism and gallantry of its members over generations.
Due to having to work on more wrist watches, and I like to remove the mainsprings from the barrel when servicing movement. I needed smaller diameter barrel mainspring winder set as my pocket watch mainspring winder is to large.
