Sinn 240 St GZ

Anyone who is at home on the world’s seas - either as a skilled sailor or a keen water sports enthusiast - knows how important it is to keep an eye on the weather. The tides are often just as important because they go a long way towards determining how things pan out. Whichever port you’re heading for, it is crucial to take a close look at the local tide table to work out the current tidal range. It is just as essential to keep checking your watch - especially if it features an interior tide bezel like the 240 St GZ.

The rotating tide bezel can be used to read the relative water level of a location in terms of current tide, i.e. the time until the next high tide. All you need to know is the time of the last high tide and correlate this with the triangular mark ‘HW 1’ on the rotating bezel. This can be taken for example from a tide table or tide calendar. The hour hand can then be used to read off the current water level on the rotating tide bezel of the 240 St GZ. You can also read off the expected relative water levels for any given time up until the time of the next high tide, which is then shown at the position ‘HW 2’.
