Important tools in a watch maker’s tool box – screws and screwdrivers

For storing and retrieving the screw drivers easily, a Bergeon stand for Screw drivers can be used. A Bergeon Torsiometer is a device which is used to measure the tightening torque of a screw driver. The Torsiometers come in varying dimensions to measure screw drivers with different diameters. To hold the Torsiometer torque tool, the Bergeon Holder for Torsiometer is used. It has a non slip base and is made of anodized aluminium.

Grub screws come in diameters ranging from 1.8 mm to 3 mm, .50mm and .6 mm to 1.6 mm. The grub screw is essential to hold the screwdriver blade securely. When the blade has to be changed, these screws will be needed and it is always a good idea to have a few spare grub screws. They generally come in packs of 10 pieces. The grub screws can be used with Bergeon or AF Swiss screw drivers.

The Bergeon individual screw drivers come without spare blades and with a single size blade. The screw drivers are top quality, chrome plate and have coloured identifying rings about them to indicate the blade size. For example, a .5 mm blade has an orange coloured ring where as a .8 mm has a yellow ring. The Bergeon screwdrivers with spare blades come as a one size tool but with 4 spare blades in a plastic tube. They are also chromium plated top quality blades and have the same coloured rings for identification. The Bergeon Crosshead Screwdriver has a coloured hexagonal head. The handle is fluted.

A&F Swiss made Cross head screwdriver set has 4 pieces with diameters of 1.5, 2, 2.5 and 3 mm and is specifically meant for watch making. They are precise, strong and comfortable to use. The screwdrivers have a ball bearing swivelling head with tempered blades and chrome plated shafts. The A&F Screwdriver Set Carousel has 9 pieces in chrome plated brass. Each screwdriver head is colour coded and they rotate as they are mounted on ball bearings. It also comes with spare blades and fixing screws.

The Bergeon 5 piece Box screwdriver Set has 5 screwdrivers in a cardboard box and each screwdriver has one spare blade supplied. The 9 piece wooden box Bergeon screwdriver set has spare blades packed into plastic tubes; the blades are chromium plated and the screwdriver sizes range from .5 mm to 2.5 mm. The Bergeon Screwdriver set on non slip rotating stand has 9 screw drivers mounted on a stable stand. Each hole is coloured. There are 9 spare blades provided with this set. The Bergeon anti magnetic screwdriver set has anti magnetic properties and has 5 screwdrivers in it from .5 mm to 1.2 mm. There are 5 spare blades, one for each screwdriver.
