Along with an eye-catching look, the new Sinn 240 St GZ comes with a function that any individual who interacts with the ocean – either as a skilled sailor or a water sports enthusiast – will like: a rotating tide bezel that can be utilized to peruse the relative water level of a location as far as momentum tide, i.e. the time until the following high tide.
Its utilization is really simple: you just need to know the time of the last high tide – taking it for instance from a tide table or tide schedule – and connect this with the triangular imprint ‘HW 1’ on the internal rotating bezel (HW stand for Hochwasser, high tide in German). The hour hand would then be able to be utilized to peruse off the normal relative water levels for some random time until the time of the following high tide, which is then shown at the position ‘HW 2’. NW indicates the low tide (Niedrigwasser in German).
The light blue rim of the rotating bezel shows the relative water level of a tide and indicates the most important water levels. The corresponding time can be perused with sufficient exactness on the fine-minutes dial. Each stroke on the fine-minutes dial is equivalent to three minutes. Obviously, the tide bezel must be readjusted for each tide.
Water resistant to 100 meters/330 feet, the 43 mm x 11 mm case is created from stainless steel with a dab blasted finish. Because of the anti-reflective treatment on the two sides of the sapphire crystal, the dull blue dial featuring indices and hands covered with luminescent tone is completely legible in any light condition.
The watch is powered by a self-winding Sellita SW 220-1 beating at 28,800 vibrations each hour and offering 38 hours of power hold. The development is stun resistant and anti-magnetic as defined by the DIN 8308 and DIN 8309 standards.
The price of the Sinn 240 St GZ is Euro 1,490 with cowhide strap or Euro 1,660 with the steel wristband. sinn.de
