U-Boat watches are hard to mistake: large cases, the crown on the left and a lever that protects it. The lines look related and differ a good deal in size, movement and water resistance. This guide sorts them out.
An Italian design
U-Boat is an Italian brand founded in 2000 by Italo Fontana. Its signature is the crown on the left side of the case, protected by a lever that locks it.
The main lines
| Line | Sizes in our stock | Movement in our stock | Water resistance in our stock |
|---|---|---|---|
| Classico | Mostly 45 and 46 mm | Mostly automatic | 100 m on most; 300 m on some |
| Darkmoon | 40, 44 and 46.5 mm | Quartz | 50 m |
| Sommerso | 46 mm | Automatic | 300 m |
| U-65 | 44 mm | Quartz or automatic | 50 m |
Figures are those of the watches listed with us; always confirm them on the listing.
- The Classico is the original U-Boat design with the left-hand crown and lever.
- The Darkmoon is the quartz line, in steel or with a black coating.
- The Sommerso is the dive watch.
- The brand also makes the Capsule, with a rounded case, and the Chimera, with chronographs and three-hand models in bold finishes.
Quartz or automatic
This matters more with U-Boat than with most brands, because the look is so similar across lines. The Darkmoon is quartz; the Classico and Sommerso are mostly automatic; the U-65 comes both ways. The Movement row in the specifications tells you.
Size
U-Boat watches are large. Check the diameter in each listing against your wrist, and compare it with a watch you own. If you are unsure about size, read our guide to choosing your watch size.
PVD and bronze
PVD is a dark coating on steel. It is durable but can show wear on sharp edges over time. Some Classico models are made in bronze, which darkens naturally with wear, or in titanium.
Every watch we sell is checked by our specialist before it ships. We are an independent retailer, not an authorized dealer of the brand; the listing says what comes with each watch.
