Just got the lowdown watch. Real nice. Bit pricey but whatever. I can get the tide prediction to match. I set it and its always an hour off in a days time. I had a vestal and i had a similar issue it seems like the analog watches kept tide bet
I have the lowdown... So, the tide meter goes off by an hour or does the actual time function not track time properly.... After switching from the Shark tidewatch to the Nixon, it took me a few days to even figure out all the button combinations and how to program the thing, but it's been a beast ever since. Had to return my first one after about 2 months of use because the seal was comprimized while surfing and any time I hit the light button, the watch would scramble and power off. Their office was like 2 blocks north of where I lived. I walked in and the game me a fresh one, But back to your question... Dunno. Never had that issue. The nearest tide areas for me are Savannah, which is like 20 miles south and Charleston, which is like 80 miles north, so I had to program the delay in it to get the exact tide to match my area.... Jersey is on there for sure though, I think north and south... Not sure about the hour thing, unless you did what I did and adjusted the location by telling it how far north or south you are... Maybe it is resetting to the original location if you did that.
I had the same problem. When configuring the time and date and whatnot, there is a setting after the 12h format option that say DST. That would be the "Daylight Savings Time" button. Mess with that setting and you should be good to go.
I got a shark classic tide watch that is awesome for the money... Never a problem and right on... My last tide watch would do the same thing- it ended up being something with the day night savings mode. Instead of changing the time manually every year- you would have to turn on And off the day light savings mode... Hope that helps!
I remember how big the manual for that watch is too. And it's printed so small. It folds out into like a 3'x3'ft sheet. It's in there somewhere on how to change the setting.
