CITIZEN BM7624-82A Eco-Drive Two-Tone 38mm Men's Watch

The CITIZEN BM7624-82A is a light-powered Eco-Drive men's watch from the Eco-Drive Axiom collection, built around a 38mm stainless steel case with two-tone silver and rose gold plating. It suits men who want one metal-bracelet watch for work and weekends, and who would rather not think about battery changes.

Inside, the H504 calibre drives a 1/1-second chronograph that counts to 60 minutes, a 24-hour sub-dial and a date window at 4 o'clock. Mineral glass protects the white dial, and the case carries a 100-metre (10 bar) water resistance rating, which covers pool laps and snorkelling. A full charge keeps the watch running for up to five months in the dark, while a fold-over clasp with push button secures the two-tone bracelet.

Key features and benefits of the Citizen BM7624-82A Eco-Drive men's watch

• Eco-Drive light-powered movement: Daylight or a desk lamp feeds the rechargeable cell that runs the watch. You never need to buy or fit a button battery, so the watch stays ready without power service stops.
• H504 calibre timing functions: The movement adds a 1/1-second chronograph good for 60 minutes, a 24-hour display and a date window at 4 o'clock. Those extras cover timing a meeting, a lap or a cooking step without reaching for a phone.
• 38mm stainless steel case: The case measures 38mm across, pairing silver-toned stainless steel with rose gold plating for warmth and contrast. That diameter sits comfortably on most men's wrists and slips under a shirt cuff.
• White dial: The white background gives high contrast for the hands and markers, so the time reads at a glance. It also gives the watch a crisp face that works with a dark suit or casual clothes.
• Two-tone stainless steel bracelet: The bracelet repeats the case finish, so the watch reads as a single piece on the wrist. Solid links can be removed by a jeweller to shorten the band and set a precise fit.
• Mineral glass: Hardened mineral crystal resists everyday scuffs better than acrylic and keeps the dial clear. The chronograph sub-dials stay readable without a haze of fine scratches.
• 100-metre water resistance (10 bar): The rating covers swimming, snorkelling and showering. It is not intended for scuba diving or high-impact water sports, where pressure goes beyond the stated limit.
• Fold-over clasp with push button: A single press opens the clasp, which folds over the bracelet rather than flexing the links. That keeps the band locked during activity and reduces wear at the fastening.
• Five-month power reserve: A fully charged cell runs the movement for up to five months with no light at all. Store the watch in a drawer for weeks and it will still show the correct time when you pick it up.
• Insufficient charge warning: The second hand switches to two-second jumps when power runs low. That gives clear notice to place the dial in bright light before the watch stops.
• Overcharge prevention: The charging circuit stops feeding the cell once it is full. Leaving the watch on a sunny windowsill will not shorten the life of the cell.

Who the Citizen BM7624-82A men's watch is for

The BM7624-82A suits a man who wants one watch to cover the office, the weekend and a swim without thinking about batteries. Two-tone steel and a white dial lean smart-casual, so the watch works with a suit, chinos or a polo shirt. The chronograph and 24-hour display help anyone who times things through the day, and the 100-metre rating means you can keep it on in the pool.

• Office and business-casual wear, where a metal bracelet matches the dress code.
• Swimming, snorkelling and beach days, within the 100-metre rating.
• Travel, since the five-month reserve survives weeks packed in a suitcase.
• Timing cooking, workouts or meetings with the 60-minute chronograph.
• Buyers who want a watch that never needs a battery change.

Less suitable if: you prefer a light watch on the wrist, because the solid stainless steel bracelet carries noticeable weight.

Using and caring for the Citizen BM7624-82A

The BM7624-82A charges from light, so give it a few hours near a window or under a lamp each week rather than leaving it in a dark drawer for long stretches. Fresh water is the simplest cleaner: rinse the bracelet after saltwater or chlorine, then dry it with a soft towel. Keep the mineral glass wiped with a microfibre cloth, and let a jeweller shorten the bracelet rather than bending links yourself.

• Rest the watch where daylight reaches the dial, even indoors, to keep the reserve topped up.
• Rinse with fresh water and dry fully after swimming, especially in salt or chlorinated water.
• Wipe the case and bracelet with a damp cloth, then buff dry to keep the two-tone plating bright.
• Ask a watch shop to remove bracelet links for a secure fit; the clasp push button handles small adjustments.
• Treat two-second jumps of the second hand as a prompt to charge in bright light for several hours.

How to choose a men's watch

Four points decide most men's watch purchases: power source, case size, water resistance and bracelet type. The Citizen BM7624-82A answers them with an Eco-Drive light-powered movement that avoids battery changes, a 38mm case that fits most wrists and cuffs, a 100-metre (10 bar) rating for swimming, and a solid stainless steel two-tone bracelet that wears dressier than leather or rubber. If you want a very light watch, look at a smaller case or a strap model instead.

Frequently asked questions

What materials make up the Citizen BM7624-82A?

The case and bracelet are stainless steel, finished in two-tone silver and rose gold plating, with a white dial under mineral glass. The plating gives the metal a warmer look than plain steel.

Is a 38mm case a good fit for most men?

Yes, 38mm is a middle-of-the-road size that sits comfortably on most wrists and fits under a shirt cuff. The solid steel bracelet adds some weight, which you will notice if you usually wear a lighter watch.

Can you swim in this watch?

Yes, the 100-metre (10 bar) rating covers swimming and snorkelling. It is not rated for scuba diving or high-impact water sports.

Does the watch need a battery?

No. The Eco-Drive movement turns light into energy and stores it in a rechargeable cell, so there is no button battery to replace.

What does the chronograph measure?

The stopwatch counts in 1/1-second steps up to 60 minutes. A 24-hour sub-dial and a date window at 4 o'clock sit alongside it on the dial.

How long does the Citizen BM7624-82A run without light?

A fully charged cell keeps it going for up to five months in total darkness. That reserve is why the watch survives weeks in a drawer or travel bag.

What comes in the box?

You receive the watch with its two-tone bracelet already fitted, the fold-over clasp with push button, and the manufacturer's documentation. No extra straps or tools are listed.

How do you look after the two-tone finish?

Rinse off sweat and salt, then dry the bracelet with a soft cloth to keep the plating looking even. As with any plated surface, heavy daily contact will eventually show wear.
