    Watchmakers screwdrivers come in sets of various different sizes. Choosing a suitable size for the screw you wish to loosen, or tighten, will reduce the risk of damaging the screw head or slot. You should choose a screwdriver with a blade width slightly smaller than the diameter of the screw head. If the blade is to large then you risk damaging, or scoring the material around the screw. If the blade is too small then the screwdriver may slip out of the slot and scratch the surrounding area. Also, if the blade is too small then you may not get enough torque to loosen or tighten the screw properly.

    • To summarise, with level 2 of this course we have introduced a guideline procedure for stripping a movement to pieces in such a way as to minimise risk of damage to the movement components by releasing all the power from the mainspring, removing the various sections of the movement including the balance and escapement, the motion work, the going barrel and train wheels and the keyless works. ...

    • Now that you have adjusted the rate of your watch movement, it is very important to put the watch through various stages of testing. ...

    • When timing a watch you would aim to test the rate in several different positions. As an example, if a watch movement is moved from a dial-up or dial-down position to a pendant, or crown, down position then you may expect a small drop in amplitude from the oscillator due to a greater amount of resistance the balance staff pivots receive from turning on their side faces as opposed from turning on the pivot tips. ...

    • As the balance oscillates, it interacts with the pallet fork twice. These are called vibrations, or beats. Effectively it is the ‘tictoc’ sound you hear with any mechanical watch movement. ...

    • This rate is governed by the balance assembly and in particular, the diameter and weight of the balance wheel, and the strength and length of the balance spring. When fine tuning the rate of a watch movement we can make adjustments to either of those two components. ...
