Just Watch mother-of-pearl women's watch steel 23 mm

At 23 mm across, this Just Watch sits neatly on a slim wrist without swamping it. It is the sort of size you notice when it is missing from a drawer full of oversized fashion watches: small, round and easy to forget you are wearing until the light catches it.

That light is the whole point. The dial is mother-of-pearl, so its colour shifts as you move your arm, from soft cream to pale pink to a hint of grey depending on where you are standing. Arabic numerals keep things readable, which matters when the dial is this compact, and the hands are luminescent for glancing at the time in a dim room.

The case is metal in a silver tone, and it is matched by a stainless steel bracelet in the same finish. The links drape smoothly around the wrist rather than sitting stiffly, and the bracelet is 12 mm wide, a proportion that suits the small case. Total length is 20 cm, and a deployant clasp closes it with a single click.

Inside, a quartz movement does the work with an analogue display. It is the simple, steady kind: nothing to wind, and only the battery to replace now and then. A mineral glass protects the dial from everyday knocks.

Water resistance is rated at 5 ATM, so rain and splashes at the sink are no problem. Swimming is a different matter, so take it off before you dive in.

Dressed up or down, it works with a shirt at the office, a jumper at the weekend and a little black dress in the evening. If you like the pearly shimmer, have a look at the rest of our jewellery watches for women too.
