Who should buy which.

The T008 38mm Titanium 50 Fathoms 3H PT5000 Dive Watch: A buyer who wants a small, light, vintage-style diver for everyday wear and swimming. Choose a larger diver with a ceramic bezel if you want modern readability, or a flatter watch if you wear slim cuffs.

The T018 Titanium PT5000 Dive Watch (Black Bezel): A buyer who wants a light, rugged, dark diver for the water and everyday wear. Choose a smaller diver if you have a small wrist, or an uncoated titanium or steel model if you do not want a coating that can wear.

Before you order.

THORN lists 13 mm thickness including the crystal (10 mm without), and it does not state an ISO dive certification or a power reserve. The bezel markings are a vintage layout, so check legibility if you time dives.

At 41.9 mm wide and 50.5 mm lug-to-lug it is a large watch, and a coating can wear with use. THORN lists a 2-year warranty on this product.
