Here we have a very unusual 1970s Chrono Marine Tide Watch with a 37.5mm plastic case, the slim profile leads to a lug-to-lug length of 45mm and a case thickness of 14mm ensuring a comfortable fit on your wrist. To access the movement you unscrew the bezel and go in through the front. On the right side a large crown. To set the watch you pull out the crown and using the local tide tables for that day you set the large hand at the exact time to either High Tide or Low Tide, the watch will now show daily under normal tidal conditions the average condition of the tides for that coastal area. A polished bezel holds a domed crystal above a blue dial with red accents. On the right side, it shows how many hours to Low tide, and on the left side, it shows the number of hours to high tide, The blue goes from a dark blue indicating high tide and a lighter blue for low tide, which is a quick and easy way of knowing what the tides are doing at that time without having to check the tide tables. The hour hand has a white arrow point complemented by a tapered red second hand. At 12 o’clock we have the Chronomarine motif and at 6 o’clock “Tide watch” 17 Jewels. On the reverse, the case back has instructions on how to remove the movement. Inside a Manually Wound 17 Jewel Swiss movement. The watch comes fitted on an 18mm grey strap.
A watch for determining the tide, who doesn't need one of these in their collection?! But seriously, how amazing, when watches were true tools designed with a purpose and use, now you'd obviously use an app or track a website for exact tides, but there's something romantic about owning something that has one simple purpose...
