ADMIRAL II Tide Clock / quartz / Arabic numerals

I bought the Wempe Tidenuhr from SVB some time ago. After only one year, the tide indicator was without function. Wempe has installed a new movement with warranty. It is a super spilleriges plastic drive. Without touching the clock was about 1.5 years again no function. The tide pointer hangs loose. Returned - Warranty expired. Repair on goodwill. The arrived again broken by the transport again. Once again sent in and repaired. After a short time without function. Pointer just lurches around and I've already treated the clock like a raw egg. You have to be afraid of every wave. Then I realized that the clock is not exactly accurate. For a clock over 500 euros. That borders on fraud for me and makes me really angry. The clock hangs in a 10 meter sailboat below deck.
