The quick answer.
Thorn Watches T018 Titanium PT5000 Dive Watch (Black Bezel) is a 41.9 mm diver watch at $179. We recommend it for a buyer who wants a light, rugged, dark diver for the water and everyday wear.
Why it belongs on the shortlist.
At 77 g, the T018 wears much lighter than a steel watch of the same size. The black coating gives it a stealthy tool-watch look, and the FKM strap suits water use.
Our verdict: light and dark.
Lightweight titanium and a black finish make this the diver you forget you are wearing. With a PT5000 and 200 m at $179, it is the version we would suggest for hot weather and active use.
What you get.
THORN lists a screw-down crown and case back, a PT5000 high-frequency movement with automatic and manual winding and a rubber strap with a second vintage-style canvas strap. Our case materials guide explains titanium.
