The face of that clock is confusing. It suggest that it's about 10 hours between high and low tide which, if the tide in Digby is not fundamentally different from anywhere else in the world, is plain wrong.

As a tidal clock it would need to make a full turn every 12h50m14s. So they probably took a stock clockwork with just an hour hand, and just slowed down the balance spring or pendulum by about 3.5% to achieve this.
