No need for a watch for tides, I just check the time of the next tide before getting out of the van, and it is sufficient.
What I look for in watches:
- lisibility: old eyes pre-dawn means that I cannot read digital watches, so even less something with the ergonomics of an airplane cockpit!
- lisibility: white hands on a black background work best
- light
- thin
- plastic (so not to damage the board)
- no distractions, such as the indication of the day of the month, a hassle to maintain.
- battery easily replaceable (4 screws), with a standard-size joint
- and the crown away from the wrist, I hate it when the crown digs in the top of my hand.
The best I found is the Rip Curl Cambridge.
It even has inside a support for the mechanism to resist shocks (unlike the Nixon watches)

PS: for a long battery life, use the "Renata" Swiss batteries.
