Luminox XB.3741. watch 45 mm 300 m

45 mm carbon compound case

The Luminox XB.3741 is a men's survival chronograph built around a 45 mm black carbon compound case. A Swiss-made quartz movement powers the chronograph, date display and integrated compass. Night-vision tubes on the hands and markers provide constant low-light legibility. Scratch-resistant sapphire crystal protects the black dial.

Suited for outdoor and maritime use

This watch serves users who need 300 m water resistance and a uni-directional rotating bezel for timed activities. The adjustable silicone strap fits a wide range of wrist sizes straight from the box. Buyers who want mechanical movement or smartwatch connectivity should look at something else.

300 m water resistance decides fit

The 300 m rating is the single specification that determines whether this model matches the intended environment. It covers professional diving and heavy surface-sport exposure. If the activity stays well below that depth, a lower-rated watch may be lighter and less costly.
