Buckeridge 19'''


A pocket watch movement, probably from the mid 19th century and of English origin is the 19 ligne movement shown here, signed by its watchmaker “Buckeridge”, and also with the name “Chippenhalm Calne”, a long-established jeweller.

Except for the balance wheel bearing, this pillar movement is free from bearing rubies.

As escapement, a sharp tooth lever escapement is used, which is typical for England in the 19th century.

On this, the pallets are recessed into the lever and the teeth of the escape wheel are, as the name indicates, sharp.

The gear train construction is pretty odd: It starts with a massive mainspring barrel, whose ratchet is located on the dial side, and which is wound by a key. Following are a pure transmission wheel of the same size, the center minute wheel, third wheel, decentral seconds wheel and escape wheel.

The role of the massive transmission wheel is not fully clear, maybe it was used to protect the center minute wheel in case of a mainspring breakage, where the instant unloading would apply too much force onto the center minute wheel.

The balance wheel is beared in a cylinder, which is mounted into the gear train plate. The balance staff itself runs in two ruby bearings, both covered with a cap jewel.

A Breguet hairspring is used, which, in combination with a long regulator arm, should increase the precision.

On the dial side, you see the ratchet. The time is also set with a key; on the cannon pinion, you can see the square, onto which the key is put.
