Lunar Tide Movement – High and Low Tide Indicator – Medium Shaft, 2-1/8” Case Size

Lunar Tide Movement – Medium Shaft, High and Low Tide Indicator

This Lunar Tide Movement is designed to track the rise and fall of tides based on the lunar day (24 hours and 50 minutes), providing accurate tidal readings. Unlike traditional clock movements, this tide movement does not tell time but instead uses a single hand to display high and low tide cycles. It’s an ideal addition to coastal and nautical-themed projects, bringing both functionality and charm to tide clocks.

**When choosing the proper batteries for your clock, please consider the following information: There are many brands of alkaline batteries available on the market today, but there are several brands out there that just don’t perform well in clocks. We recommend using Rayovac or Duracell brand. Other brands, such as Energizer, have extra plastic coating on the negative end of the battery, which can cause clocks to malfunction or not work properly at all. Alkaline batteries are the only type of battery that should be used in clocks. Lithium powered or re-chargeable batteries will cause your clock to malfunction, or not function at all. Lithium and rechargeable batteries are meant for “high-drain” devices, such as digital cameras, etc. Alkaline batteries are best used in “low-drain” devices, which includes clock movements.
