The Citizen CA4420-21X is a generously sized watch built around a stainless steel case and a green dial. It measures 43 mm across.
Case and Wrist Presence
Case diameter is 43 mm, worked in stainless steel. The surface treatment is polished. At 43 mm it lands in the range most men’s wrists take comfortably, and it will sit under a cuff.
Reading the Dial
The dial is green. Chronograph registers are recessed into the dial, which adds depth to the face without crowding the hour track.
Movement and Functions
A light-powered movement drives the watch.
- Chronograph – stopwatch timing from the dial
- Water resistance – 10 ATM (100 metres)
- Mineral crystal – protecting the dial
Strap, Clasp and Fit
The strap is leather. Leather softens and takes the shape of the wrist over the first few weeks, and it is the easiest material to replace later if you want a different look.
Water Resistance and Everyday Durability
The watch is rated to 10 ATM, or 100 metres of static pressure. In practical terms that covers rain, hand washing, showering and recreational swimming. It is not a dive watch, so leave it behind for scuba diving and keep it away from high-pressure water jets. Make sure the crown is fully seated before any contact with water.
A mineral crystal protects the dial – harder than acrylic and more shatter-resistant than sapphire, which is a sensible trade-off on a case this size.
Who This Watch Suits
- An everyday wrist size that still reads as a proper men’s watch
- Building a green-led accessory wardrobe
- Anyone who will actually use a stopwatch – or simply wants the busier dial that comes with one
- Smart-casual dressing, where a bracelet would read too heavy
- Daily wear that includes rain, washing up and the occasional swim
- Gift buyers looking for something recognisable, boxed and properly warranted
Styling Notes
Green has moved from novelty to staple. It works against brown leather, cream and navy, and reads as a considered choice rather than a safe one. The leather strap pulls the whole watch towards smart-casual – it will look right with a jacket and wrong with a wetsuit.
Care and Maintenance
A watch at this level rewards very little maintenance, but the little it asks for makes the difference between one that still looks sharp in five years and one that does not. Rinse the case in fresh water after a swim, especially in the sea, and dry it before it goes back on. Leather and water are a poor combination: a soaked strap stiffens and cracks as it dries. Let it breathe between wears and it will last years rather than months.
Keep it clear of perfume and solvents, off the speaker on your desk, and out of direct sun when you take it off.
About the Brand and Ownership
Citizen watches sit in the sweet spot between fashion and function: recognisable design, real build quality, and a price that does not ask you to think of the watch as an investment. Basic care goes a long way – keep it clear of solvents and perfume, rinse the strap if it has been in salt water, and store it somewhere dry.
The Short Version
What you are getting is an everyday size that still has presence, a chronograph dial with enough going on to hold your eye. A leather strap that softens the whole thing rounds it out. It is not trying to be a heirloom piece and it does not price itself like one. It is a well-made, recognisable watch that does the job every day and looks considered doing it.
