Citizen Promaster Automatic Diver Titanium NB6021-17E

Product Information
About this watch
Men's dive watch with an automatic movement instead of a battery. Black runs through the entire watch – dial, bezel and strap – with a silver-coloured frame as the only contrast. It is built for water first and office week second, and belongs to those who prefer to wear a watch with real diving functionality rather than a sporty replica of the same look.
Materials & fit
The case measures 41 mm in diameter, is rounded in shape and made of titanium with a silver-coloured finish. On top is a rotatable dive bezel with a fluted, silver-coloured edge and a lume-marked triangle at twelve o'clock. The dial is beneath sapphire glass, and the crown is fluted at three o'clock. The strap is silicone with a checkered surface, 20 mm wide, and fastens with a buckle.
Highlights
- Automatic movement – the watch is wound by the motion of the wrist instead of running on battery.
- 20 ATM, 200 meters, and the marking DIVER'S 200m printed on the dial: the level is sufficient for diving, not just swimming.
- Luminous hands and indices keep readability intact in the dark.
- Date window at three o'clock, with a white background that lifts the number out of the black dial.
Good to know
- What does the bezel do? Rotate it so that the zero mark meets the minute hand when you start – the 60-minute scale will then show how many minutes have passed.
- Does it need to be wound? An automatic movement lives on motion. If the watch is left unused for a while, it will stop, and then the time and date are reset before it is put on again.
- Can the strap be changed? The silicone strap is a universal strap in standard width, so it can be replaced with any strap of the same dimensions.
- After a swim in the sea, a rinse in fresh water is sufficient – salt that dries in tends to get into the grooves of the bezel and the pattern of the strap.
