A watch strong and practical

It corresponds to what I expected. Solid I used to go surfing in me I display tides per 2h programmed on the nearest port. With an indication of low coefficient medium or high. It is therefore no solar battery change with tightness again. I hope to keep it long. I did not give it 5 stars because the look is not great it is light but a bit bulky compared to the display. But hey I quibble.
