The Swiss based Bergeon, are the makers of some of the finest watchmakers' tools. The ergonomic stainless steel screwdriver series come in all sizes. They are extremely well machined and finished and as the name suggests, they are extremely comfortable to use. The difference between the ergonomic set and the standard set is the colour coded swivel heads. The size of the heads make them more visible and gives you better grip, thus easier to handle. The hexagonal head comes in self-lubricating, synthetic POM (Derlin) material, which adds to the ergonomics of these.
