Catalogue Note

The movement of this watch has an interesting, unusual and early application of a hairspring. One end of a straight 'spring' is attached to the balance itself, whilst the other is held between two curb pins mounted to the foot of the balance cock. The watch is regulated by altering the length of the straight spring in a similar manner to the so-called 'Barrow' regulator. Turning the worm (endless screw) which is mounted to the foot of the cock, causes a slide to move up or down the length of the spring thereby altering its length. The slide indicates to a scale engraved to the cock's foot, opposite the worm.
