I recently bit the bullet and purchased a Bergeon service kit, having previously damaged watches with cheap chinesium tools.

Yesterday I wanted to change the strap on my Oris, and to my annoyance an overtight screw on one of the lug bars wrecked the tip of one of the Bergeon screwdrivers!

Not since the days of xmas-cracker tools made from chewing-gum have I known a driver damaged by a screw, rather than the other way around - but then the thought struck me: is it deliberate? i.e. is it better to damage the driver than the screw, since a new tip is cheap, where damage to a decent watch most certainly isn't...

Anyone know if this is the case. Bergeon are characteristically unforthcoming.
