Munro No. 11

The No. 11 is an interpretation of the classic astronomical regulator in mantle-scaled half seconds proportions. The mahogany and glass case has the classic break-arch door, and is positioned on a fitted block of tan marble to complement the case.

The narrow movement is positioned in front of the massive gridiron temperature compensating pendulum for a compact layout, with the weight drop positioned in the recess of lyre-shaped mounting bracket.

The movement and pendulum are close together in this extremely compact case, and the weight descends between them. Note how one side of the movement is free of mechanism to provide weight clearance, and the threaded turning pulley guides the weight forward as it drops to clear the movement at the top, and also the pendulum bob as it drops.

The pulley shroud holds the pulley partly inside the weight to preserve weight drop. Unlike the traditional screwed bracket arrangement, it has a pair of hooks which hold a crossbar cast into the body of the weight.
