This is our smallest pendulum movement and has been "standard" in the market for years. You can choose from 4 shaft lengths and 3 sizes of pendulum bobs. All pendulums consist of a 16" adjustable pendulum with your choice of 3 pendulum bob sizes. You can easily trim the pendulum rod to any length under 16".

​

These movements will operate a second hand, but second hands are considered optional. All models have a 5/16" shaft diameter so a 3/8" mounting hole is the correct size to drill in your case.
