Off the cuff I would suggest the Timex Expedition Tide
Bonanza 69 (Never heard of them) but they have one for $70
REI 169:
Or the Casio digitals

The 10 Best Tide Watches for Fishermen
For me, I have a Marathon TSAR that I set the pip to the next high or low tide (tides change from place to place)
Put any of these watches on a NATO strap with some good spring bars if you don't want to lose it. A NATO (or ZULU) strap runs through both springbars so that if one breaks you don't lose the whole watch
They also have a 17" commercial divers strap designed to go around wet/dry suits that you can cut down
Where I get my NATO straps:

What I want to do one of these days is take an ETA GMT movement and change the GMT gearing and make an automatic tide watch - someday
If anyone is interested I have a Luminox on a Commercial Orange dive strap I might let go for $100
