Citizen Promaster Diver BN0150-28E review

What it is

The Promaster Diver is Citizen's long-running quartz dive series. This BN0150 reference is the Eco-Drive solar version with a unidirectional rotating bezel, a clear dial and a large case. It sits below Citizen's automatic and Aqualand models and offers the most dive capability for the money in the Citizen line.

Citizen has built dive watches since the 1970s, and the Promaster name carries a tool-watch reputation that goes beyond the price. This one is often chosen as a first serious diver.

The movement

It uses Citizen's Eco-Drive technology: light charges a rechargeable cell through the dial, and a full charge runs the watch for months without any light. Because it is quartz, accuracy is better than any mechanical watch, typically within a few seconds a month. The cell lasts many years, so servicing is minimal compared with an automatic. It is a set-and-forget design for anyone who dislikes winding or battery changes.

Citizen's own figures give months of running from a full charge. If the watch is left in a drawer for a long time, put it in daylight to recover rather than assuming it has failed.

On the wrist

The case is 44 mm across and the watch is chunky, designed to be read underwater. It is substantial on a small wrist but comfortable on larger ones. Check the strap type on the listing, as the Promaster range includes both polyurethane straps and steel bracelets, and a diver's strap or bracelet will include some extension for use over a wetsuit.

Rubbery straps are comfortable in water, but they can pick up lint and can perish after some years. A steel bracelet adds weight but is easy to rinse.

Water and everyday wear

With a 200 m rating and ISO 6425 diver standard, it is rated for scuba and proper water use, not just swimming. The crystal is mineral, which is strong for everyday use but scratches more easily than sapphire. The dial has generous lume on the hands and markers for low-light reading. The bezel ratchets one way, which is a safety feature for timing dives.

The screw-down crown should be fully tightened before swimming, and a rubber seal needs routine checking by a watchmaker every few years.

Against the alternatives

The Orient Kamasu RA-AA0002L19B is an automatic diver with a sapphire crystal for similar outlay. The Casio MDV-107-1A1VEF is a cheaper quartz diver that is less refined. The Seiko Prospex SPB299J is a mechanical dive watch at a higher level. Within Citizen's own range, the Citizen Promaster Diver NY0040-09W is the automatic version.

Who it's for, and who should skip it

It suits people who want a dive-capable watch that needs no winding or battery changes, whether they dive or simply like the look. Skip it if you want a sapphire crystal, a smaller case, or a mechanical movement to enjoy.
