YQSDG 55mm DIY Tide Quartz Controlled Repair Wall Clock Movement Motor Mechanism Replacement 115mm Hands Fitting Motor Watch

This clock movement is aligned to the daily lunar cycle. As east coast US tides are synced to the lunar cycle, the clock can predict tides. If you do a bit of research, it’s best to set high tide on the day of a new moon. This minimizes weekly tide fluctuations.

I've had the same beautiful tide clock for over 25 years but the mechanism finally gave up. This new mechanisim fits perfectly

It works! Installation was pretty simple. Inexpensive.

L'aiguille n'entre pas dans l'arbre. Le trou de l'aiguille est de la même grosseur que l'arbre, impossible de poset l'aiguille. Décevant.

I bought a beautiful ceramic tide clock but unfortunately it had a 12 hour clock work in it making it useless as a tide clock, but I bought this tide clock for $7 something and it is keeping great time. After 4 days, it's spot on with the tides. My son wanted to keep the tide clock on his boat, so I bought another one and bought this 'tide' clock at the same time, replacing it immediately. Unfortunately, this one is just a regular 12 clock movement. It is out of sync with the tide in just a couple days. Now do I try to buy this tide clock again hoping I get a correct one? I don't know.
