··schizophrenic pizza orderer and watch collectorCame here looking to find a perfect screwdriver for my Speedy Hesalite but after reading the whole thread it seems like it doesn't exist. I wanted to add something here because I didn't see it on the thread.
Did you miss @Archer s post on the first page that tells you the perfect screwdriver
There is no Omega New speedmaster Bracelet screwdriver.
The bracelet screw is listed as - 124ST3307 | SCREW M1.40 ØH1.9 L1.8 STEEL
So head diameter (also the slot length) is 1.9 mm, so a 180 screwdriver will fit the length of the slot - screwdrivers tend to jump from 180 to 200. No matter what screwdriver you purchase, the thickness of the driver will most likely have to be fitted to the screw slot width. I am not familiar with what you have ordered, but you don't really want a hollow found blade for this as those require a closer fit. A wedge blade is appropriate for the screw, and you should file the driver so the blade almost touches the bottom of the slot, but not quite.
You may have to heat the screw - boiling water is not hot enough to break the bond of the Loctite used, so you may need a small torch - I have a small Mastercraft butane version at my bench for heating specific areas to break the Loctite.
Cheers, Al
