Barrel Opener and Closer

by Jordan Ficklin

Tags: ,

Barrel Closer There are many ways to open and close barrels. These two ways are the ones I use. On the left is my standard barrel closer. For those of you who don’t know the barrel is the first wheel (gear) in the gear train and it houses the mainspring. It needs to be opened when serviced so it can be cleaned and a new mainspring inserted. The barrel is placed on the bottom portion with the lid on top and then the barrel closer lid is placed on top. It is important because it applies even pressure to the barrel lid and keeps it from deforming. The surface is concave which is used when the barrel lid needs to be domed slightly to close up the endshake. Most barrels can be opened by pushing down on the barrel drum and letting the arbor push off the lid but with some small barrels this can be tricky. The tool on the right is Rolex specific barrel opener for ladies calibers. it works like a charm, you place the barrel inside and push down on the tool and the lid pops off.

I made the barrel closer as a micromechanics project while in watchmaking school. It is a great simple tool. They can also be purchased from material parts houses.
