CASIO Watch Lineage Tough Solar Radio Watch Titanium MULTIBAND6 LCW-M100TD-1A3JF Men's Watch
This watch is always on time because it synchronizes with atomic radios globally.
The battery never runs out because the watch face is a solar cell.
You don't have to take off the watch because it is water resistant to 5 bars/50 bars.
It looks like an "adult" watch though it has standard digital features:
Date, world time, stopwatch, countdown, and alarms.
The titanium makes this watch almost indestructible.
The sapphire glass only had a minor scratch when a person fell pinning my wrist to a rock face.
Everything still worked, but I replaced the glass anyway.
Not bad for 4 years.
