Quick TakeThe 240 St GZ is not simply a time-telling device; it's an ocean-goer's companion. The bead-blasted stainless-steel case, housing the automatic SW 220-1 movement, speaks of steadfast dependability. The deep blue dial mirrors the mysterious sea, highlighted by bright, luminescent markers to guide you, whether tracking passing hours or tides. The internal tide bezel transforms the watch from just an accessory into an instrument, especially useful when you're aware of how tidal flows affect plans. This watch is more than a time-keeper. It provides the user with a feeling of being an explorer charting courses. With a robust 43mm case and anti-magnetic properties, it's prepared for almost anything. It is truly an adventure on your wrist. The date and day functions complete what is needed from a utility perspective.

DescriptionThe Sinn 240 St GZ, reference 240.011, is built around a bead-blasted stainless steel case, measuring 43mm in diameter and 11mm in thickness. The band lug width accommodates a 22mm strap or bracelet. Component integration adheres to the D3-System for the crown, enhancing overall structural resilience. The case back is screw-fastened, ensuring the integrity of the internal mechanisms. Total weight, excluding any strap, is documented at 85 grams. Protection of the dial is accomplished via a sapphire crystal, which has received anti-reflective treatment on both the interior and exterior surfaces. This crystal selection guarantees optimum clarity and scratch resistance under varied environmental conditions.

The dial is a distinctive dark blue. Applied indices, as well as the hour and minute hands, are coated with a luminescent material to permit legibility in low-light scenarios. Further enhancing the low light capability are the marks on the interior rotating tide bezel that are also coated with luminescent colour. Functionality extends beyond standard timekeeping; the watch incorporates a day and date display, positioned traditionally, and the critical interior tide bezel. The operation of the tide bezel involves aligning the "HW 1" marker with the known time of the last high tide. Subsequent water levels, leading up to the next high tide ("HW 2" marker), can then be inferred using the hour hand in conjunction with the bezel's markings. The watch movement is a mechanical SW 220-1, incorporating a self-winding mechanism. This movement operates at 28,800 semi-oscillations per hour and integrates 26 bearing jewels to minimize friction. The movement allows for a hacking seconds function (hand adjustment with seconds stop function) and has been determined to be anti-magnetic, fulfilling the specifications defined in DIN 8309. Water and pressure resistance are certified to 10 bar, as specified by standard DIN 8310. Additionally, the design is resilient against low-pressure environments.
